Recombinant Human IL-1RA

Product Details

Catalog Number: 200-01RA
Description:

Interleukin-1 receptor antagonist (IL-1RA) is a naturally-occurring, inflammatory-inhibitor protein.  It inhibits the activity of IL-1α and IL-1β by competitively blocking their binding to type I and type II receptors.  IL-1RA is produced by corneal epithelial cells, monocytes, neutrophils, macrophages, and fibroblasts.  Therapeutically, IL-1RA may help in the treatment of sepsis, cachexia, rheumatoid arthritis, chronic myelogenous leukemia, asthma, psoriasis, and inflammatory bowel disease.  Recombinant Human IL-1RA is a 17.2 kDa protein consisting of 153 amino acid residues.
