Anti-Human BCA-1 (Clone 53610)

Quality Tested by Leinco ELISA Sandwich: This antibody is useful as the capture antibody in a sandwich ELISA. The suggested coating concentration is 2-8 µg/ml. A suitable detection antibody is PN:B116 at a concentration of approximately 0.1-0.4 µg/ml. A suggested standard for this assay is PN:B111.
Western Blotting: To detect Human BCA-1 this monoclonal antibody can be used at a concentration of 0.1 µg/ml. This monoclonal antibody should be used in conjunction with compatible second-step reagents such as PN:M114 and a chromogenic substrate such as PN:T343. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used. A suitable Western blotting control is PN:B111.

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.

Neutralization: This antibody is useful for neutralization of Human BCA-1 bioactivity. The antibody dose required to neutralize 50% (ND₅₀) of the biological activity of Human BCA-1 (at 0.05 ng/ml) is 0.3 - 0.9 µg/ml.
CyTOF-ready:Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Mouse Anti-Human B Cell-Attracting Chemokine-1 (BCA-1) (Clone 53610) recognizes an epitope on Human BCA-1. This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

This monoclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco's phosphate buffered saline (1X PBS) pH 7.2 - 7.4 containing 5.0% w/v trehalose with no calcium, magnesium or preservatives present.
