IFNG, also known as interferon gamma, is secreted by lymphocytes stimulated by mitogen and is involved in the differentiation, maturation, and proliferation of hematopoietic cells. Natural human interferon-gamma is composed of 143aa residues without cysteine residues and is glycosylated. Proteolytic processing produces C-terminal heterogeneity, with proteins ending alternatively at Gly-150, Met-157 or Gly-161. Source: Recombinant protein corresponding to aa24-161 of human IFNG, fused to His-tag at N-terminal expressed in E. coli. Molecular Weight: ~18.5kD Endotoxin: ~1EU/1ug of protein (LAL) Amino Acid Sequence: MGSSHHHHHH SSGLVPRGSH MQDPYVKEAE NLKKYFNAGH SDVADNGTLF LGILKNWKEE SDRKIMQSQI VSFYFKLFKN FKDDQSIQKS VETIKEDMNV KFFNSNKKKR DDFEKLTNYS VTDLNVQRKA IHELIQVMAE LSPAAKTGKR KRSQMLFRG Storage and Stability: May be stored at 4C for short-term only.
