Introduction
XCL1 is a small cytokine belonging to the XC chemokine family that is also known as lymphotactin. It is located in high levels in spleen, thymus, intestine and peripheral blood leukocytes, and at lower levels in lung, prostate gland and ovary. Cellular sources for XCL1 include activated thymic and peripheral blood CD8+ T cells. This chemokine attracts T cells. In humans, XCL1 is closely related to another chemokine called XCL2, whose gene is found at the same locus on chromosome 1. XCL1 induces it chemotactic function by binding to a chemokine receptor called XCR1.
Description
XCL1 Human Recombinant produced in E.Coli is a single,non-glycosylated, polypeptide chain containing 114 amino acids (22-114 a.a.) and having a molecular mass of 12.5 kDa. The XCL1 is fused to a 20 amino acid His Tag at N-terminus and purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
