    Product Description

     

    The homeostatic chemokine CXCL13 (also called B cell-attracting chemokine 1 [BCA-1] or B-lymphocyte chemoattractant [BLC]) is constitutively expressed in secondary lymphoid tissue and initiates lymphoid neogenesis when expressed aberrantly. 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. CXCL13 is a homeostatic chemokine for lymphocyte homing and positioning within follicles of secondary lymphoid tissues, acting through its cognate receptor, CXCR5. Besides, CXCL13 is a potent chemokine, produced by mature and recently recruited macrophages to sites of inflammation, which has antimicrobial and anti-angiogenic properties.

    Physical Appearance

    Sterile Filtered White lyophilized (freeze-dried) powder.

    Purity

    > 97% by SDS-PAGE and HPLC analyses.

    Biological Activity

    The biological activity determined by a chemotaxis bioassay using human B cells is in a concentration range of 1.0-10 ng/mL. Fully biologically active when compared to standard.

    Endotoxin

    1.0 EU per 1μg of the protein by the LAL method.

    Formulation

    Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 100 mM NaCl.

    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℃. Further dilutions should be made in appropriate buffered solutions.


    Shipping and Storage

     

    The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.

    Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.

     

    Cautions


    Avoid repeated freeze-thaw cycles.

    For your safety and health, please wear lab coats and disposable gloves for operation.
