Active Recombinant Human IFNG Protein (Gln24-Gln166), GMP Grade, Animal-Free

• Cat.No.: IFNG-30HG
• Product Overview: GMP recombinant human IFN-gamma protein (Gln24-Gln166) with an N-terminal Met was expressed in E. coli, produced in an Animal-Free laboratory and manufactured and tested under cGMP guidelines.

Specification

• Description: This gene encodes a soluble cytokine that is a member of the type II interferon class. The encoded protein is secreted by cells of both the innate and adaptive immune systems. The active protein is a homodimer that binds to the interferon gamma receptor which triggers a cellular response to viral and microbial infections. Mutations in this gene are associated with an increased susceptibility to viral, bacterial and parasitic infections and to several autoimmune diseases.
• Source: E. coli
• Species: Human
• Bio-activity: Measured in anti-viral assays using HeLa human cervical epithelial carcinoma cells infected with encephalomyocarditis (EMC) virus. The ED50 for this effect is 0.15-0.75 ng/mL.
  The specific activity of recombinant human IFN-gamma is >2.0 x 107 IU/mg, which is calibrated against the human IFN-gamma Standard.
