CXCL13-26649TH
Optional Service: Optional requirements on this protein
Product Overview :
Recombinant Human CXCL13 protein was expressed in Escherichia coli.
Description :
C-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 murine protein and 23–34 % amino acid sequence identity with other known CXC chemokines.
Source :
E.coli
Species :
Human
Form :
Lyophilized from a 0.2μm filtered concentrated solution in 20 mM PB, pH 7.4, 100 mM NaCl.
Bio-activity :
Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human B cells is in a concentration range of 1.0-10 ng/ml.
Molecular Mass :
Approximately 10.3 kDa, a single non-glycosylated polypeptide chain containing 87 amino acids.
Less than 1 EU/μg of rHuBCA-1/CXCL13 as determined by LAL method.
Purity :
>97% by SDS-PAGE and HPLC analysis.
Storage :
Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70 centigrade as supplied. 1 month, 2 to 8 centigrade under sterile conditions after reconstitution. 3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
Reconstitution :
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤-20 centigrade. Further dilutions should be made in appropriate buffered solutions.
