      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.

    • Background

      Interferons, a family of signaling proteins, play a pivotal role in the immune system’s defense against viral infections and other threats. Among these, Interferon W1 (IFNW1), a member of the Type I interferon family, has emerged as a key player in orchestrating antiviral responses and modulating immune reactions. This research embarks on a detailed exploration of the IFNW1 protein, unveiling its structural intricacies, signaling pathways, and its broader implications in immune regulation and disease. By delving into IFNW1, scientists aim to comprehend the nuances of its functions, decipher its interactions within the complex interferon network, and explore its potential applications in therapeutic interventions and beyond.

      Structural Insights into IFNW1:

      IFNW1, like other Type I interferons, exhibits a unique tertiary structure that enables it to interact with specific cell surface receptors. This interaction triggers a cascade of events, leading to the activation of various antiviral genes and immune modulatory pathways. Understanding the structural basis of IFNW1 is crucial for elucidating its binding affinities, biological activities, and its significance in immune responses.

      Signaling Pathways and Antiviral Defense:

      IFNW1 engages with its cognate receptors, initiating Janus kinase (JAK)-Signal Transducer and Activator of Transcription (STAT) signaling pathways. This activation leads to the transcription of interferon-stimulated genes (ISGs) with potent antiviral properties. IFNW1’s ability to induce an antiviral state in infected and neighboring cells is fundamental for restricting viral replication and curtailing the spread of infections. Additionally, IFNW1 plays a role in modulating adaptive immune responses, contributing to the broader immune defense mechanisms.

      IFNW1 in Immunomodulation and Disease:

      Beyond its antiviral functions, IFNW1 is implicated in immunomodulation and disease pathogenesis. Dysregulation of IFNW1 signaling is associated with autoimmune disorders, including lupus and rheumatoid arthritis, highlighting its involvement in immune-related diseases. Moreover, IFNW1 is being explored in cancer immunotherapy, where its ability to modulate the tumor microenvironment and enhance immune surveillance presents opportunities for novel treatment strategies.

      Therapeutic Potential and Future Prospects:

      The unique properties of IFNW1, particularly its role in immune regulation and antiviral defense, position it as a potential therapeutic target. Research efforts are directed towards harnessing its immunomodulatory functions for developing therapies against infectious diseases, autoimmune disorders, and certain cancers. Additionally, understanding IFNW1’s interactions with other components of the immune system opens avenues for innovative approaches in personalized medicine and targeted immunotherapies.

      IFNW1 Protein, as an integral component of the interferon network, stands as a sentinel in the body’s defense against viral invasions and immune dysregulations. Its multifaceted roles in antiviral defense, immune modulation, and disease pathogenesis underscore its significance in biology and medicine. As researchers delve deeper into the intricacies of IFNW1, they pave the way for innovative therapies, immunomodulatory interventions, and a deeper understanding of immune responses. This research not only illuminates the pivotal role of IFNW1 but also holds the promise of transformative advancements in medicine, shaping the future of immunology and disease therapeutics.

    • Introduction

      Interferon Alpha And Beta Receptor, also known IFNAR1, belongs to the class II cytokine receptor family. IFNAR1 protein forms one of the two chains of a receptor for interferons alpha as well as beta. IFNAR1 binds and activates the receptor which stimulates Janus protein kinases, which in turn phosphorylate some proteins, including STAT1 & STAT2. Furthermore, IFNAR1 also functions as an antiviral factor.

    • Background

      IFN-alpha forms are produced by monocytes/macrophages, lymphoblastoid cells, fibroblasts, and a number of different cell types following induction by viruses, nucleic acids, glucocorticoid hormones, and low-molecular weight substances (n-butyrate, 5-bromodeoxy uridine). At least 23 different variants of IFN-alpha are known. The individual proteins have molecular masses between 19-26 kDa and consist of proteins with lengths of 156-166 and 172 amino acids. All IFN-alpha subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-alpha subtypes differ in their sequences at only one or two positions. Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxy-terminal end. Disulfide bonds are formed between cysteines at positions 1/98 and 29/138. The disulfide bond 29/138 is essential for biological activity while the 1/98 bond can be reduces without affecting biological activity. All IFN-alpha forms contain a potential glycosylation site but most subtypes are not glycosylated. In contrast to IFN-gamma IFN-alpha proteins are stable at pH2.

      There are at least 23 different IFN-alpha genes. They have a length of 1-2 kb and are clustered on human chromosome 9p22. It is not known whether all these genes are expressed following stimulation of the cells. In some cell systems expression of some subtypes (IFN-alpha-1, IFN-alpha-2, IFN-alpha-4) is stronger than those of others. IFN-alpha genes do not contain intron sequences found in many other eukaryotic genes (see also: gene expression). Based upon the structures two types of IFN-alpha genes, designated class 1 and II, are distinguished. They encode proteins of 156-166 and172 amino acids, respectively. Deletions covering 9p22 are observed frequently in cells of lymphoblastoid leukemias. It is not known to date whether this is of significance with respect to IFN expression.

      The gene encoding the IFN-alpha receptor maps to human chromosome 21q22.1. IFN-alpha and IFN-beta are thought to bind to the same IFN binding subunit which is expressed in 100-5000 copies in IFN-alpha sensitive and -resistant cells and is associated with other as yet unidentified proteins. The IFN-omega (Omega IFN) also binds to the IFN-alpha/IFN-beta receptor. Another receptor expressed on B-lymphocytes is identical with CD21. This receptor also binds Epstein-Barr virus through its gp350/220 coat protein.Signal transduction mechanisms elicited after binding of IFN-alpha to its receptors involves tyrosine phosphorylation (see also: PTK; protein tyrosine kinase) of various non-receptor tyrosine kinases belonging to the Janus kinases. Soluble forms of the IFN-alpha receptor, corresponding to truncated forms of the extracellular domain of the cell surface IFN-alpha receptor, have been found in human serum and in normal human urine.

      All known subtypes of IFN-alpha show the same antiviral antiparasitic, antiproliferative activities in suitable bioassays although they may differ in relative activities. Human IFN-alpha is also a potent antiviral substance in murine, porcine, and bovine cell systems. Human IFN-alpha is less active in rodent cells. Site-directed mutagenesis techniques have been used to create some variants of certain subtypes (IFN-alpha-2) that display approximately 100-fold enhanced antiviral activities in mouse cells.

      IFN A 2B HUMAN Protein has a total Mw of 19.4kDa.
