Room temperature in continental US; may vary elsewhere.


Human BCA-1/CXCL13 is identified as an efficacious and selective attractant for B lymphocytes, also acts as a B cell homing chemokine. Human BCA-1 competes with radiolabeled interferon gamma (IFN-γ) inducible protein 10 (IP-10) for binding to the human CXCR3 receptor. Furthermore, human BCA-1 is an efficacious attractant for human CXCR3 transfected cells; BCA-1-induced chemotaxis is inhibited by a monoclonal antibody against human CXCR3. Indeed, BCA-1 attenuates the calcium flux induced by IP-10. In addition, human BCA-1 is an agonist in stimulating GTPγS binding[1].
