||Recombinant murine IFN-γ is a 15.6 kDa protein containing 134 amino acid residues.
||IFN-γ is an acid-labile interferon produced by CD4 and CD8 T lymphocytes as well as activated NK cells. IFN-γ receptors are present in most immune cells, which respond to IFN-γ signaling by increasing the surface expression of class I MHC proteins. This promotes the presentation of antigen to T-helper (CD4+) cells. IFN-γ signaling in antigen-presenting cells and antigen-recognizing B and T lymphocytes regulates the antigen-specific phases of the immune response. Additionally, IFN-γ stimulates a number of lymphoid cell functions including the anti-microbial and anti-tumor responses of macrophages, NK cells, and neutrophils. Human IFN-γ species-specific and is biologically active only in human and primate cells.
||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.
