BCA1 Antibody / B cell-attracting chemokine 1 / CXCL13, 100 ug

C-X-C motif chemokine 13, also known as B lymphocyte chemoattractant (BLC), is a protein that in humans is encoded by the CXCL13 gene. CXCL13 is a small cytokine belonging to the CXC chemokine family. Its gene is mapped to human chromosome 4 in a cluster of other CXC chemokines. This protein contains 109 amino acids. It is expressed highly in the liver, spleen, lymph nodes and gut of humans. It induces chemotaxis of BLR1-expressing B cells.
