IFN gamma is a potent multifunctional cytokine primarily produced by T cells and natural killer cells. IFN gamma exerts a variety of antiproliferative, immunoregulatory and pro-inflammatory biological activities in response to binding at specific cell surface receptors. RANDOX recombinant IFN gamma comprises a 143 amino acid fragment (24-166) corresponding to the mature soluble IFN gamma chain protein and is expressed in E. coli with an amino-terminal hexahistidine tag.
