USAGE For Research Use Only! Not to be used in humans


Human Chemokine (C-X-C motif) ligand 14(hCXCL14),also known as breast and kidney-expressed chemokine (BRAK), MIP-2 gamma, kidney-expressed chemokine (KEC), and B cell and monocyte-activating chemokine (BMAC), is a CXC chemokine constitutively expressed in certain normal tissues but is reduced or absent from many established tumor cell lines and human cancers. CXCL14 is known to be a chemo-attractant for monocyte and dendritic cells. CXCL14 inhibits angiogenesis and exhibits antimicrobial activities. Mature human and mouse CXCL14 differ by only 2 residues.
