Murine IFN-gamma is a regulatory protein produced by activated NK cells and CD4+TCR alpha-beta+, CD8+TCR alpha-beta+, and TCR gamma-delta+ T cells. Biological activities of IFN-gamma include specific binding to a single class of high affinity receptors. Recombinant murine IFNg is a 15.6kD protein containing 134 amino acid residues.

Biological Activity:
Determined by its ability to inhibit the proliferation of mouse WEHI-279 cells. ED50 is 0.2ng/ml, corresponding to a specific activity of 5 x 10e6units/mg.
