Recombinant Rat IL22 Protein (Leu27-Val172)
Product Description
Cat
IMP-10553
Official Symbol
Il22
Product Overview
Recombinant Rat IL-22 protein (Leu27-Val172) with an N-terminal Met was expressed in E. coli.
Description
This gene is a member of the IL10 family of cytokines that mediate cellular inflammatory responses. The encoded protein functions in antimicrobial defense at mucosal surfaces and in tissue repair. This protein also has pro-inflammatory properties and plays a role in in the pathogenesis of several intestinal diseases. The encoded protein is a crucial cytokine that regulates host immunity in infectious diseases, including COVID-19 (disease caused by SARS-CoV-2).
