Function

Chemotactic for B-lymphocytes but not for T-lymphocytes, monocytes and neutrophils. Does not induce calcium release in B-lymphocytes. Binds to BLR1/CXCR5.

Biological Context

Subcellular Location: Secreted
Tissue Specificity: Highest levels in liver, followed by spleen, lymph node, appendix and stomach. Low levels in salivary gland, mammary gland and fetal spleen

Product Specifications

Recombinant Human C-X-C motif chemokine 13 protein (CXCL13) is a recombinant protein from Homo sapiens (Human), expressed in E.Coli, covering amino acids 23-109aa, with Tag-Free tag, molecular weight 10.3 kDa, purity >97% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.
