Recombinant Human IL1B Protein (117-269aa), Tag Free

Product Description

Cat

IMP-9543

Official Symbol

IL1B

Product Overview

Recombinant human IL-1beta was expressed in E. coli and purified by using conventional chromatography techniques.

Description

Interleukin-1 (IL-1) has been considered a potentially important inflammatory mediator. It is composed of two distinct proteins, called as IL-1alpha and IL-1beta. IL-1beta is a proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells. Both IL-1alpha and IL1beta bind to the same receptor and they are structurally related polypeptides that share approximately 20% amino acid.
