IFN Gamma / Interferon Gamma
IFN-gamma is an acid-labile interferon produced by CD4 and CD8 T lymphocytes as well as activated NK cells. IFN-gamma receptors are present in most immune cells, which respond to IFN-gamma signaling by increasing the surface expression of class I MHC proteins. This promotes the presentation of antigen to T-helper (CD4+) cells. IFN-gamma signaling in antigen-presenting cells and antigen-recognizing B and T lymphocytes regulates the antigen-specific phases of the immune response. Additionally, IFN-gamma stimulates a number of lymphoid cell functions including the anti-microbial and anti-tumor responses of macrophages, NK cells, and neutrophils. Human IFN-gamma species-specific and is biologically active only in human and primate cells. Recombinant murine IFN-gamma is a 15.6 kDa protein containing 134 amino acid residues.
Greater than 98% by SDS-PAGE and HPLC
Determined by its ability to inhibit the proliferation of murine WEHI-279 cells. The expected ED50 is <=0.2 ng/ml, corresponding to a specific activity of >=5 x 10^6 units/mg.
