Recombinant Human IL21, StrepII-tagged

• Cat.No.: IL21-292H
• Product Overview: Purified, full-length human recombinant IL21 protein (amino acids 23-155, 133 a.a.) with StrepII tag, produced in human cells. Predicted molecular weight: 15.5 kDa. (Accession NP_001193935; UniProt Q9HBE4)

Specification

• Description: IL21 is a member of the common-gamma chain family of cytokines with immunoregulatory activity. The encoded protein plays a role in both the innate and adaptive immune responses by inducing the differentiation, proliferation and activity of multiple target cells including macrophages, natural killer cells, B cells and cytotoxic T cells. Dysregulation of this gene plays a role in multiple immune-mediated diseases including lupus, psoriasis and chronic inflammatory diseases.
