Recombinant Human IFN-α2b

General description

Interferon Gamma is a type II interferon that orchestrates cell-mediated immunity, macrophage activation, and antiviral responses. It is essential for Th1 polarization, M1 macrophage polarization, and tumor immunosurveillance. Recombinant Human IFN-γ Protein (Y01801) is expressed from E. coli cells. It contains AA Gln 24 - Gln 166 (Accession # P01579), and is widely used in advanced cell culture, immunology research, and cell therapy quality control.

Application

· Th1 Cell Polarization — Drives T-bet expression and IFN-γ production in activated CD4+ T cells.

· M1 Macrophage Activation — Induces classical activation with enhanced antigen presentation and microbicidal activity.

· Tumor Immunosurveillance Research — Models IFN-γ-mediated tumor rejection and immune checkpoint dynamics.

· Cell Therapy Potency Assays — Validates T cell functionality and serves in release criteria for therapeutic products.

· Serum-Free Culture Systems — Suitable for chemically defined and xeno-free cell culture media.

Backgroud

IFN-α2b is a member of the type I interferon family produced by plasmacytoid dendritic cells in response to viral nucleic acids. It signals through the IFNAR1/IFNAR2 receptor complex, activating JAK1/TYK2-dependent STAT1/STAT2 signaling and driving the expression of hundreds of interferon-stimulated genes with antiviral, antiproliferative, and immunomodulatory functions. IFN-α2b has been used clinically for decades to treat chronic hepatitis B and C, hairy cell leukemia, melanoma, and multiple sclerosis. In research, it is employed to establish antiviral states, study interferon signaling pathways, and model autoimmune and inflammatory conditions.

Q&A

Q1: What is IFN-α2b mainly used for?

IFN-α2b is primarily used for antiviral research, oncology studies, autoimmune disease modeling, and dendritic cell maturation.

Q2: Is this IFN-α2b suitable for serum-free culture systems?

Yes. EastMabBio recombinant IFN-α2b is compatible with serum-free, xeno-free, and chemically defined media systems.

Q3: How should recombinant IFN-α2b be stored?

Lyophilized protein should be stored at -20°C or below. After reconstitution, aliquot and avoid repeated freeze-thaw cycles.

Q4: What shipping conditions are used?

Products are shipped on dry ice with validated cold-chain packaging to maintain stability during international transportation.

Q5: Do you provide QC documents?

Yes. COA, MSDS, TSE-BSE statements, endotoxin reports, bioactivity data, and additional QC documentation are available upon request.
