Predicted Molecular Mass:9.8 kDa Activity:Measured by its ability to chemoattract BaF3 mouse pro‑B cells transfected with human CXCR5.The ED₅₀ for this effect is typically 0.5-2µg/mL. Molecule Information: CXCL13/BLC/BCA-1 Aliases: BCA-1; BLC Entrez Gene IDs: 10563 (Human); 55985 (Mouse) Background: CXCL13/BLC/BCA-1 B cell-attracting chemokine 1(BCA-1), also known as B-lymphocyte chemoattractant (BLC), is a CXC chemokine that is constitutively expressed in secondary lymphoid organs. Mature human BCA-1 shares 64% amino acid sequence identity with the mouse protein.
