{"product_id":"abm223264","title":"Recombinant Human BCA-1\/CXCL13 protein","description":"\u003ch3\u003eBackground\u003c\/h3\u003e\u003cp\u003eC-X-C motif chemokine 13 encoded by the CXCL13 gene located on human chromosome 4 is constitutively expressed in secondary lymphoid organs. It is also known as B lymphocyte chemoattractant (BLC). As its name suggests, CXCL13 is selectively chemotactic for B cells belonging to both the B-1 and B-2 subsets, and elicits its effects by interacting with chemokine receptor CXCR5. It and its receptor CXCR5 control the organization of B cells within follicles of lymphoid tissues. Recombinant human CXCL13 is a single non-glycosylated polypeptide chain containing 87 amino acids and 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.\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003eExpression system\u003c\/dt\u003e\n\u003cdd\u003eEscherichia coli.\u003c\/dd\u003e\n\u003cdt\u003ePurity\u003c\/dt\u003e\n\u003cdd\u003e\u0026gt; 97 % by SDS-PAGE and HPLC analyses.\u003c\/dd\u003e\n\u003cdt\u003eMolecular weight\u003c\/dt\u003e\n\u003cdd\u003eApproximately 10.3 kDa, a single non-glycosylated polypeptide chain containing 87 amino acids.\u003c\/dd\u003e\n\u003cdt\u003eEndotoxin\u003c\/dt\u003e\n\u003cdd\u003eLess than 1 EU\/ug of rHuBCA-1\/CXCL13 as determined by LAL method.\u003c\/dd\u003e\n\u003cdt\u003eForm\u003c\/dt\u003e\n\u003cdd\u003eSterile Filtered White lyophilized (freeze-dried) powder.
