Recombinant Human CXCL14 (BRAK)

Chemokine (CXC motif) ligand 14, also known as breast and kidney-expressed chemokine (BRAK), is a CXC chemokine that is a potent chemoattractant for neutrophils but not for T-cells, B-cells, monocytes or granulocytes. Mature CXCL14 has many conserved features of the CXC family and is 30% homologous to the MIP-α and MIP-β sequences, but differs in that it has an additional five amino acid sequence in between the third and fourth cysteines and a short N-terminus. It is usually highly expressed near its fibroblast source and in epidermal fibroblasts and keratinocytes of skin, but is absent from cancer cells.

Storage Conditions

The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
