    • Introduction

      Pancreatitis-associated protein (PAP) is a secretory protein not normally expressed in healthy pancreas but highly induced during acute pancreatitis. While PAP has been shown to be anti-bacterial and antiapoptotic in vitro, its definitive biological function in vivo is not clear. Using antisepse oligonucleotides, inhibition of PAP expression significantly worsened pancreatitis in a rat model. During pancreatitis, PAP released by the pancreas could mediate lung inflammation through induction of hepatic TNF- alpha expression and subsequent increase in circulating TNF-alpha.
      PAP is activated in primary liver cancers. In normal liver, the protein is undetectable in normal mature hepatocytes and found only in some ductular cells, representing potential hepatic progenitor cells. PAP can be considered hepatic cytokine that combines mitogenic and anti-apoptotic functions regarding hepatocytes, and consequently acts as a growth factor in vivo to enhance liver regeneration. In pancreatic cancor, PAP was overexpressed in 79% (30 of 38) of pancreatic ductal adenocarcinoma, 19% (7 of 36) of chronic pancreatitis, and 29% (2 of 7) of mucinous cystadenoma. PAP was found in malignant ductular structures in pancreatic carcinomas as well as in benign proliferating ductules and acinar cells in chronic pancreatitis. Elevation of PAP in patients with pancreatic cancer is not merely explainable by concomitant pancreatitis, but seems to be due to increased PAP production by the cancer cells and is also correlated to tumour load as expressed by the UICC stages.
      Epithelial expression of PAP was induced under intestinal mucosal inflammation initiated by exposure to commensal bacteria or DSS as well as inflamed IBD colon. Increased serum level of PAP diagnosed ileal location in active Crohn disease with a sensitivity of 60%, a specificity of 94%, a positive predictive value of 84% and a negative predictive value of 81%. Elevated serum PAP (> 50 ng/mL) is significantly associated with disease activity and ileal location of Crohn disease.

    • Introduction

      Platelet factor-4 is a 70-amino acid protein that is released from the alpha-granules of activated platelets. Its major physiologic role appears to be neutralization of molecules on the endothelial surface of blood vessels, thereby inhibiting local antithrombin III activity and promoting coagulation. As a strong chemoattractant for neutrophils and fibroblasts, PF4 probably has a role in inflammation and wound repair. Oncostatin-A is a member of the CXC chemokine family. Furthermore it is used as an inhibitor in the angiogenesis during tumor therapy.

    • Introduction

      The Trefoil Factor peptides (TFF1, TFF2 and TFF3) are stable secretory proteins expressed in the gastrointestinal tract (gastric mucosa), and are involved in intestinal mucosal defense and repair. TFF1 is an essential protein for normal differentiation of the antral and pyloric gastric mucosa and functions as a gastric-specific tumor suppressor gene. TFF1 is a stabilizer of the mucous gel overlying the gastrointestinal mucosa that provides a physical barrier against various noxious agents. TFF1 protects the mucosa from isults, stabilizes the mucus layer, & affects healing of the epithelium. TFF1 is commonly expressed in tumors. TFF1 is related with the cell membrane of MCF-7 cells. High levels of TFF1 and TFF2 are found in serum from inflammatory bowel disease.

    • Introduction

      Fibroblast Growth Factors (FGFs) comprise a family of at least eighteen structurally realted proteins that are involved in a multitude of physiological and pathological cellular processes, including cell growth, differentation, angiogenesis, wound healing and tumorgenesis. The biological activities of the FGFs are mediated by a family if type I transmembrane tyrosine kinases which undergo dimerization and autophosphorylation after ligand binding. Four distinct genes encoding closely related FGF receptors, FGFR-1to -4 are known. Multiple forms of FGFR-1 to -3 are generated by alternative splicing of the mRNAs. A frequent splicing event involving FGFR-1 and -2 results in receptors containing all three Ig domains, referred to as the alpha isoform, or only IgII and IgIII, referred to as the ? isoform. Only the alpha isoform has been identified for FGFR-3 and FGFR-4. Additional splicing events for FGFR-1 to -3, involving the C-terminal half of the IgIII domain encoded by two mutually exclusive alternative exons, generate FGF receptors with alternative IgIII domains (IIIb and IIIc). A IIIa isoform which is a secreted FGF binding protein containing only the N-terminal half of the IgIII domain plus some intron sequences has also been reported for FGFR-1. Mutations in FGFR-1 to -3 have been found in patients with birth defects involving craniosynostosis.

This gene has been localized to a cluster of related genes at chromosome region 5q31, which is known to be associated with interstitial deletions in the 5q- syndrome and acute myelogenous leukemia. Other genes in the cluster include those encoding interleukins 4, 5, and 13.
      GM-CSF stimulates the growth and differentiation of hematopoietic precursor cells from various lineages, including granulocytes, macrophages, eosinophils and erythrocytes.

    • Amino Acid Sequence

      The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Pro-Ala-Arg-Ser.

    • Background

      Recombinant Granulocyte-Macrophage Colony-Stimulating Factor (GMCSF) is a protein that plays a crucial role in the production and differentiation of white blood cells, including granulocytes and macrophages. It is a potent stimulator of hematopoietic stem cells, which are responsible for the production of all blood cells in the body. Recombinant GMCSF is a synthetic version of the protein that is produced using recombinant DNA technology.

      Recombinant GMCSF has been extensively studied for its potential therapeutic applications in a variety of medical conditions, including cancer, autoimmune diseases, and infectious diseases. In cancer, GMCSF is used as an immunostimulatory agent to enhance the immune response against cancer cells. By stimulating the production and differentiation of white blood cells, GM-CSF can increase the number of immune cells that can recognize and attack cancer cells. This approach has been successfully used in the treatment of several types of cancer, including melanoma and leukemia.

      In autoimmune diseases, recombinant GMCSF has been investigated as a potential treatment for conditions such as rheumatoid arthritis and multiple sclerosis. These diseases are characterized by an overactive immune response that attacks healthy tissues in the body. By modulating the immune response, GMCSF may be able to reduce inflammation and prevent further damage to affected tissues.

      In infectious diseases, recombinant GMCSF has been studied as a potential treatment for conditions such as sepsis and HIV/AIDS. In sepsis, a severe bacterial infection, GMCSF may be able to stimulate the production of white blood cells and improve the immune response against the infection. In HIV/AIDS, GMCSF may be able to enhance the immune response against the virus and reduce the risk of opportunistic infections.

      Recombinant GMCSF is typically administered by injection, either directly into the affected tissue or into the bloodstream. It is generally well-tolerated, although some patients may experience side effects such as fever, fatigue, and muscle pain.

      In conclusion, recombinant GMCSF is a promising therapeutic agent with potential applications in a variety of medical conditions. Its ability to stimulate the production and differentiation of white blood cells makes it a valuable tool in the treatment of cancer, autoimmune diseases, and infectious diseases. Ongoing research is likely to uncover new uses for this protein and further refine its therapeutic potential.

    • Background

      IFN-gamma Human

      About IFN-gamma Human:

      IFN-gamma, often known as interferon gamma (and originally known as immune interferon), is a soluble, dimerized cytokine that is the only interferon in the type II class. Besides its primary function in preventing the spread of the vesicular stomatitis virus, interferon gamma release assays are extensively employed in the diagnosis of tuberculosis. IFN-gamma, encoded by the IFNG gene in humans, controls immunological responses by cell signaling, particularly through the JAK-STAT pathway. Subsequently, interferon gamma plays a crucial role in cancer immunotherapy by preventing tumor growth, managing immune defenses against pathogens and monitoring cells activity. In this article we will delve into the science behind IFN-gamma and explain its significance in biomedical research.



      Description:

      IFN-gamma Human Recombinant is a single non-glycosylated, polypeptide chain containing 144 amino acids and having a molecular mass of 17kDa that its original source is Escherichia Coli. This product appears as a sterile-filtered white lyophilized powder, ensuring purity and stability. Its formulation involves lyophilization from a filtered concentrated solution in PBS (pH 4.6). Its purity is determined both by analysis by RP-HPLC and SDS-PAGE and is therefore greater than 98%. In terms of stability, lyophilized IFN gamma is stable at room temperature for three weeks. However, it is preferable to store it desiccated below -18°C. In any case, you should prevent freeze thaw cycles. Additionally, reconstitution of IFN-gamma is recommended in sterile distilled water or 20mM AcOH, maintaining a concentration of at least 100µg/ml.

      Protein Function:

      Interferon gamma is a key player in immune control. It is a protein that plays a major role in complex cell signaling networks. The JAK-STAT pathway, which is essential for immunological regulation, is triggered by IFN-gamma through its interaction with the heterodimeric receptor. IFN-gamma's ability to regulate inflammation, apoptosis, cytokine signaling, and cell proliferation through protein mediated signaling skills is crucial for maintaining immune vigilance and response mechanisms. The incorporation of IFN-gamma into our product is validated by protein quantitation using two independent methods: UV spectroscopy and RP-HPLC.

      Applications and Usage:

      IFN-gamma Human is tailored for laboratory research, serving as a vital tool in elucidating immune mechanisms, exploring antiviral features, and unraveling tumor suppressor functions.

      Safety Information:

      IFN-gamma Human is only intended to be used in laboratory research, in line with safety protocols. It emphasizes adherence to ethical and regulatory norms and is not designed for use as household chemicals, pharmaceuticals, agricultural goods, or food additives.

    More Info

    • Introduction

      All three VEGF receptors belong to the class III subfamily of receptor tyrosine kinases (RTKs) characterised by the seven immunoglobulin-like loops in the extracellular domain. The expression of VEGFR-1 to -3 is almost exclusively restricted to hematopoietic precursor cells, vascular and lymphatic endothelial cells and to the monocyte/macrophage lineage. They play key roles in vasculogenesis, hematopoiesis, angiogenesis and lymphangiogenesis. The FLT-4 cDNA encodes a 1298 amino acid (aa) residue precursor protein with a 23 aa residue signal peptide. Mature VEGFR-3/FLT-4 is composed of a 751 aa residue extracellular domain, a 22 aa transmembrane domain and a 482 aa residue cytoplasmic domain. Both VEGF family members VEGF-C and VEGF-D have been shown to bind and activate VEGFR-3/FLT-4. The Flt-4 gene is widely expressed in the early embryo but becomes restricted to the lymphatic endothelial a latter stages of development. It is important for lymphangiogenesis.
