CXCL13, known as BCA-1 (B cell-attracting chemokine 1) or BLC (B-lymphocyte chemoattractant), is an efficacious attractant selective for B lymphocytes through binding to the BLR1/CXCR5 receptor[1]. CXCL13 is a homeostatic chemokine, and is constitutively secreted by stromal cells in B-cell areas of secondary lymphoid tissues (follicles), such as spleen, lymph nodes, tonsils, and Peyer's patches[2]. BCA-1/CXCL13 Protein, Mouse (HEK293, Fc) is produced in HEK293 cells with a N-Terminal Fc-tag. It consists of 88 amino acids (I22-A109) .
