BCA-1/CXCL13 Protein, Human is a recombinant, tag-free chemokine produced in Escherichia coli and supplied as a lyophilized material for in vitro research. CXCL13 selectively attracts B lymphocytes via the CXCR5 receptor and has validated biological activity in chemotaxis and cell proliferation assays, making it suitable for functional and signaling studies.
