Recombinant Human IL-1ra/IL-1F3 Protein Summary
Product Specifications
Product Datasheets
Carrier Free
CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.
In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Scientific Data
Recombinant Human IL-1ra/IL-1F3 (Catalog # 280-RA) inhibits IL-1a-dependent cell proliferation of the D10.G4.1 mouse helper T cell line. The ED50 for this effect is 5-40 ng/mL in the presence of 50 pg/mL of Recombinant Human IL-1a/IL-1F1 (Catalog # 200-LA).
1 μg/lane of Recombinant Human IL-1ra/IL-1F3 was resolved with SDS-PAGE under reducing (R) conditions and visualized by silver staining, showing a single band at 20 kDa.
Reconstitution Calculator
Background: IL-1ra/IL-1F3
IL-1ra was originally isolated from the urine of patients with monocytic leukemia and has also been purified from adherent monocytes. The naturally occurring, fully glycosylated form has an apparent molecular weight of about 25,000 Daltons. The protein shows 26% amino acid homology to IL-1 beta and 19% homology to IL-1 alpha. It will compete with either factor for receptor binding, but does not interact with either one. Human IL-1ra will bind to both types of IL-1 receptor (I and II) on human cells, but reportedly will not block binding to the type II receptor on murine pre-B cell lines. The recombinant, non-glycosylated form of IL-1ra blocks binding of IL-1 to its receptor equally as well as the naturally-occurring, glycosylated form. The IL-1ra has been shown to block the inflammatory responses induced by IL-1 both in vitro and in vivo. Currently, pre-clinical and clinical studies are underway to test possible therapeutic applications for IL-1ra in the treatment of sepsis, rheumatoid arthritis and chronic myelogenous leukemia.
