Human Lymphotactin (XCL1) Recombinant

Recombinant Lymphotactin is a disulfide-linked homodimeric protein consisting of 93 amino acid residues, and migrates as an approximately 10 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding human lymphotactin (XCL1) mature chain was expressed inE. coli.

Background

XCL1, also known as lymphotactin or ATAC, is the sole member of the C subgroup of chemokines, and is produced mainly by activated CD8 T cells (and to a lesser extent by NK and mast cells) . The chemotactic activity of XCL1 is restricted to lymphocytes and has no effect on monocytes.
