Recombinant Mouse BCA-1/ BLC (CXCL13)

Product Synonym Names
BCA 1 Mouse; BCA-1/BLC Mouse Recombinant (CXCL13); C-X-C motif chemokine 13; B lymphocyte chemoattractant; CXC chemokine BLC; Small-inducible cytokine B13; Cxcl13; Blc; Scyb13
Product Synonym Gene Name
Research Use Only
For Research Use Only. Not for use in diagnostic procedures.
3D Structure
ModBase 3D Structure for O55038
E Coli
Greater than 97.0% as determined by SDS-PAGE.
The BCA1 protein was lyophilized from a 0.2?m filtered solution in Acetonitrile and TFA.
Sterile Filtered White lyophilized (freeze-dried) powder.
Biological Activity
The ED50, as measured by its ability to chemoattract human CXCR5-transfected mouse BaF3 cells, is less than 2 ug/ml.
It is recommended to reconstitute the lyophilized CXCL13 in sterile 18M Omega -cm H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.
Preparation and Storage
Lyophilized BCA1 although stable at room temperature for 3 weeks, should be stored desiccated below -18 degree C. Upon reconstitution BCA1 should be stored at 4 degree C between 2-7 days and for future use below -18 degree C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Other Notes
Small volumes of BCA1 recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
BCA1 recombinant protein
Introduction: BCA-1 is a CXC chemokine that is highly expressed in thesecondary lymphoid organs, such as follicles of the spleen, lymph nodes, and Peyer's patches. CXCL13 promotes the migration of B lymphocytes (compared to T cells and macrophages), by stimulating calcium influx into, and chemotaxis of, cells expressing Burkitt's lymphoma receptor 1 (BLR1). BCA1 therefore function in the homing of B lymphocytes to follicles. Human BCA-1 shares a 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 BCA1 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 BCA1. Among cells of the hematopoietic lineages, the expression of BLR-1, now designated CXCR-5, is restricted to B lymphocytes and a subpopulation of T helper memory cells.

Description: CXCL13 Mouse Recombinant (22-109) produced in E Coli is a single, non-glycosylated, polypeptide chain containing 88 amino acids and having a molecular mass of 10kDa.The BCA-1 is purified by proprietary chromatographic techniques.
