Beschreibung

Biochem/physiol Actions

BCA-1 is a potent chemoattractant for B lymphocytes, but not T lymphocytes, monocytes, or neutrophils.

BCA-1 is a potent chemoattractant for B lymphocytes, but not T lymphocytes, monocytes, or neutrophils. Its specific receptor BLR1 is a G protein-coupled receptor originally isolated from Burkitt′s lymphoma cells. Among cells of the hematopoietic lineages, the expression of BRL1, now designated CXCR5, is restricted to B lymphocytes and a subpopulation of T helper memory cells.

Potent chemoattractant for B lymphocytes, but not T lymphocytes, monocytes, or neutrophils.

The biological activity of human BLC/BCA-1 is measured by its ability to chemoattract mouse BaF/3 cells transfected with human CXCR5.

Physical form

Lyophilized from a 0.2 μm filtered solution in 35% acetonitrile and 0.1% TFA containing 50 μg bovine serum albumin per 1 μg of cytokine.
