Recombinant Rhesus IL-1α

Description :
FAQ COA 已发表文献 Interleukin-1 alpha (IL1a) is also known as IL-1A, IL1,and is a cytokine of the interleukin-1 family.Among various species, the amino acid sequence of mature IL-1 alpha is conserved 60% to 70% and human IL-1 has been found to be biologically active on murine cell lines.It possesses metabolic, physiological, haematopoietic activities, and plays one of the central roles in the regulation of the immune responses.IL-1is a major immunoregulatory/proinflammatory cytokine which also affects fibroblast proliferation and function and therefore it was of interest to investigate whether its constitutive expression influences the in vivo tumorigenic potential of transformed fibroblastoid cell lines Product Properties Synonyms BAF, IL-1F1, LAF, LEM, preinterleukin 1 alpha, pro-interleukin-1-alpha Accession P48089 GeneID 700193 Source E.coli-derived Rhesus Macaque IL-1, Ser113-Ala271.
