Scientific Data

Western Blot Detection of Recombinant Human CXCL13/BLC/BCA-1 antibody by Western Blot. View Larger

Detection of Recombinant Human CXCL13/BLC/BCA‑1 by Western Blot. Western blot shows 100 ng of Recombinant Human CXCL13/BLC/BCA-1 (Catalog # 801-CX) and Recombinant Mouse CXCL13/BLC/BCA-1 (Catalog # 470-BC). PVDF Membrane was probed with 1 µg/mL of Mouse Anti-Human CXCL13/BLC/BCA-1 Monoclonal Antibody (Catalog # MAB801) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for CXCL13/BLC/BCA-1 at approximately 12 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.

Neutralization Chemotaxis Induced by CXCL13/BLC/BCA‑1 and Neutralization by Human CXCL13/BLC/BCA‑1 Antibody. View Larger

Chemotaxis Induced by CXCL13/BLC/BCA‑1 and Neutralization by Human CXCL13/BLC/BCA‑1 Antibody. Recombinant Human CXCL13/BLC/BCA-1 (Catalog # 801-CX) chemoattracts the BaF3 mouse pro-B cell line transfected with human CXCR5 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Mouse Anti-Human CXCL13/BLC/BCA-1 (0.05 µg/mL) is neutralized (green line) by increasing concentrations of Human CXCL13/BLC/BCA-1 Monoclonal Antibody (Catalog # MAB801). The ND50 is typically 0.3-0.9 µg/mL.

Background: CXCL13/BLC/BCA-1

CXCL13, also known as B-lymphocyte chemoattractant (BLC), is a CXC chemokine that is constitutively expressed in secondary lymphoid organs. BCA-1 cDNA encodes a protein of 109 amino acid residues with a leader sequence of 22 residues. Mature human BCA-1 shares 64% amino acid sequence similarity with the mouse protein and 23-34% amino acid sequence identity with other known CXC chemokines. Recombinant or chemically synthesized BCA-1 is a potent chemoattractant for B lymphocytes but not T lymphocytes, monocytes or neutrophils. BLR1, a G protein-coupled receptor originally isolated from Burkitt’s lymphoma cells, has now been shown to be the specific receptor for BCA-1. Among cells of the hematopoietic lineages, the expression of BLR1, now designated CXCR5, is restricted to B lymphocytes and a subpopulation of T helper memory cells. Mice lacking BLR1 have been shown to lack inguinal lymph nodes. These mice were also found to have impaired development of Peyer’s patches and defective formation of primary follicles and germinal centers in the spleen as a result of the inability of B lymphocytes to migrate into B cell areas.
