Chicken IFN gamma (Yeast-derived Recombinant Protein)

Protein Background

Interferon-gamma (IFN-gamma) is a dimerized soluble cytokine that is the only member of the type II class of interferons. This interferon was originally called macrophage-activating factor, a term now used to describe a larger family of proteins to which IFN-gamma belongs. IFN-gamma, or type II interferon, is a cytokine that is critical for innate and adaptive immunity against viral and intracellular bacterial infections and for tumor control. Aberrant IFN-gamma expression is associated with a number of autoinflammatory and autoimmune diseases. The importance of IFN-gamma in the immune system stems in part from its ability to inhibit viral replication directly, but, most important, derives from its immunostimulatory and immunomodulatory effects. IFN-gamma is produced predominantly by natural killer (NK) and natural killer T (NKT) cells as part of the innate immune response, and by CD4 and CD8 cytotoxic T lymphocyte (CTL) effector T cells once antigen-specific immunity develops.

Recombinant Chicken IFN gamma Catalog Number CHKF0001 contains a single amino acid substitution compared to NCBI reference sequence NP_990480.1 (Thr at position 93 in place of Ile). This amino acid substitution was corrected to match the published sequence. The corrected recombinant protein is available (Catalog Number CHFI0001-5/CHFI0001-25/CHFI0001-100/CHFI0001-500) (Ile present at position 93).
