    More Info

    • Introduction

      Prefoldin subunit 2 (PFDN2) belongs to the prefoldin beta subunit family. The PFDN2 protein is one of 6 subunits of prefoldin, which is a molecular chaperone complex that binds and stabilizes newly synthesized polypeptides, thus allowing them to fold correctly. PFDN2 binds specifically to cytosolic chaperonin (c-CPN) and transfers target proteins to it. PFDN2 also binds to a nascent polypeptide chain and promotes folding in an setting in which there are many competing pathways for nonnative proteins.

    • Synonyms

      Prefoldin subunit 2, PFDN2, PFD2.

    • Physical Appearance

      Sterile Filtered colorless solution.

    • Stability

      Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.

    More Info

    • Introduction

      CES1 is a part of the alpha/beta fold hydrolase familyand participates in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. CES1hydrolyzes aromatic and aliphatic esters, although it has no catalytic activity toward amides or a fatty acyl-CoA ester. CES1hydrolyzes the methyl ester group of cocaine to form benzoylecgonine and catalyzes the transesterification of cocaine to form cocaethylene. CES1also plays a role in detoxification in the lung and protection of the central nervous system from ester or amide compounds.CES1 is found in most tissues, mainly in the liver.

    • Synonyms

      Liver carboxylesterase 1 isoform a, CES1, ACAT, CE-1, CEH, CES2, hCE-1, HMSE, HMSE1, PCE-1, REH, SES1, TGH, Acyl-coenzyme A:cholesterol acyltransferase, Brain carboxylesterase hBr1.

    • Introduction

      Chemokine (C-X-C motif) ligand 11 (CXCL11) is a small cytokine belonging to the CXC chemokine family that is also called Interferon-inducible T-cell alpha chemoattractant (I-TAC) and Interferon-gamma-inducible protein 9 (IP-9). It is highly expressed in peripheral blood leukocytes, pancreas and liver, with moderate levels in thymus, spleen and lung and low expression levels were in small intestine, placenta and prostate. Gene expression of CXCL11 is strongly induced by IFN-g and IFN-b, and weakly induced by IFN-a. This chemokine elicits its effects on its target cells by interacting with the cell surface chemokine receptor CXCR3, with a higher affinity than do the other ligands for this receptor, CXCL9 and CXCL10. CXCL11 is chemotactic for activated T cells. Its gene is located on human chromosome 4 along with many other members of the CXC chemokine family.

    More Info

    • Introduction

      L-Selectin belongs to a family of divalent cation-dependent carbohydrate-binding glycoproteins or adhesion molecules. The L-Selectin molecule is composed of various domains: one homologous to lectins, one to epidermal growth factor, and two to the consensus repeat units found in C3/C4 binding proteins.
      L-selectin is expressed constitutively on lymphocytes, monocytes and granulocytes and interacts specifically with carbohydrate groups on activated endothelial cells. L-Selectin may be shed by proteolytic cleavage and circulating levels in biological fluids may be used as an indicator of various pathological conditions. L-Selectin is cleaved by ADAM17.
      L-selectin works as a "homing receptor" for leukocytes to enter secondary lymphoid tissues via the high endothelial venules. Ligands present on endothelial cells will attach to leukocytes expressing L-selectin, which causes the leukocytes to become localized at that juncture. The receptor is also located on the cell surfaces of "naive" T cells, which have not yet encountered their particular antigen. This surface expression is lost following the cells activation.

    More Info

    • Introduction

      Ferritin is a fairly large, iron-storage heteropolymeric protein composed of 2 subunit types, light Ferritin & heavy Ferritin polypeptides, which is expressed in most kinds of cells and co-assemble in different proportion in a tissue-specific manner. Ferritin is composed of 24 self-assembled polypeptide subunits of the heavy and light ferritin chains and is characterized by the capacity to remove Fe from solution in the presence of oxygen.
      Ferritin light polypeptide protein is the main intracellular iron storage protein in prokaryotes and eukaryotes. Variation in ferritin subunit composition influence the rates of iron uptake and release in various tissues. A key function of ferritin is the storage of iron in a soluble and nontoxic state. Defects in this light chain ferritin gene are associated with several neurodegenerative diseases and hyper ferrit anemia-cataract syndrome.
      Ferritin stores iron in a soluble, nontoxic, readily accessible form. Ferritin is needed for iron homeostasis. Iron is taken up in the ferrous form and deposited as ferric hydroxides after it has been oxidized.

    • Background

      Desmin, an intermediate filament protein, plays a fundamental role in maintaining the structural integrity and function of muscle cells. While extensive research has been conducted on desmin in mammals, the study of desmin in chickens is an emerging area with considerable potential for advancing our understanding of muscle biology. Chickens are valuable model organisms for studying muscle development, growth, and regeneration due to their relatively simple muscular system and economic significance in poultry production. This research aims to provide a comprehensive exploration of desmin in chickens, shedding light on its functions and implications for muscle structure and function.

      The primary objective of this research is to elucidate the role of desmin in chicken muscle structure and development. In vitro and in vivo experiments, utilizing chicken cell cultures and embryonic models, will be conducted to investigate how desmin contributes to the organization of muscle fibers, sarcomere assembly, and myofibrillogenesis. Understanding these mechanisms is fundamental for deciphering the complexities of muscle development in chickens.

      The second objective is to assess the clinical and economic relevance of desmin in poultry production. Studies involving broiler chickens will be conducted to evaluate the impact of desmin mutations or variations on muscle growth, meat quality, and disease susceptibility. These investigations may provide valuable insights into potential strategies for enhancing poultry production efficiency and meat quality.

      The third objective is to explore the potential applications of desmin in biotechnology and tissue engineering. Research will investigate the use of desmin-expressing chicken cells as models for studying muscle-related diseases and for developing tissue engineering approaches for muscle repair and regeneration.

      By delving into the functions and roles of desmin in chickens, this research aims to expand our knowledge of muscle biology, its implications for poultry production, and its potential applications in biotechnology and regenerative medicine.

      Blood samples from tissue donors were tested and found to be negative for HBsAg, HIV-1 and HIV-2 antibodies and HCV.

    • Background

      Carcinoembryonic Antigen, commonly known as CEA, is a glycoprotein that was initially identified as a tumor marker. Over the years, research into CEA has unveiled its intricate involvement in various physiological processes, not only in cancer but also in the context of normal development and inflammatory conditions. This research aims to delve into the multifaceted roles of CEA, exploring its structural intricacies, regulatory mechanisms, and its implications in health, disease, and beyond.

      Structural Complexity of CEA:

      CEA, belonging to the immunoglobulin superfamily, is a complex glycoprotein featuring multiple structural domains. Its diverse forms and glycosylation patterns contribute to its functional versatility. CEA is primarily expressed in fetal tissues, but its presence is often detected in adults under pathological conditions, especially in various types of cancer.

      CEA in Cancer Biology:

      CEA was first recognized as a biomarker for colorectal cancer, but its overexpression is not limited to this context. Elevated CEA levels have been associated with several other malignancies, including breast, lung, and pancreatic cancers. CEA’s involvement in cancer biology ranges from promoting angiogenesis and metastasis to inhibiting immune responses, making it a critical player in tumor progression and evasion.

      Beyond Cancer: CEA in Development and Inflammation:

      While CEA’s role in cancer is prominent, recent studies have uncovered its participation in normal physiological processes. During embryonic development, CEA is involved in cell adhesion, contributing to tissue organization and morphogenesis. Additionally, CEA expression can be induced in inflammatory conditions, suggesting its involvement in immune responses and tissue repair mechanisms.

      CEA as a Diagnostic and Therapeutic Target:

      The diverse expression patterns of CEA in various diseases make it a valuable diagnostic tool. CEA assays are widely used for cancer screening, monitoring disease progression, and assessing treatment efficacy. Moreover, CEA’s presence on the surface of cancer cells has made it a target for immunotherapy, enabling the development of targeted therapies aimed at specifically eradicating CEA-positive tumor cells.

Syntaxin 4 is vital for normal regulation of glucose metabolism uptake in skeletal muscle and decline in STX4 protein levels lead to reduction of whole-body hormone-stimulated glucose metabolism. STX4 is expressed in neutrophils and neutrophil-differentiated HL-60 cells. The STX4 expression in neutrophils increases with differentiation.

    • Synonyms

      Syntaxin 4, syntaxin 4A (placental), STX4A, Renal carcinoma antigen NY-REN-31, p35-2.

    • Physical Appearance

      Sterile Filtered colorless solution.

    • Introduction

      CUB Domain Containing Protein 1, also known as CDCP1 is a transmembrane protein which contains three extracellular CUB domains. CDCP1 is implicated in cell adhesion and cell matrix association. In addition, CDCP1 takes part in the regulation of anchorage versus migration or proliferation versus differentiation through its phosphorylation. CDCP1 is also a novel marker for leukemia diagnosis as well as for immature hematopoietic stem cell subsets. Furthermore, the extracellular region of human CDCP1 shares amino acid identity sequence with the mouse CDCP1.
