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.
Product Name- Recombinant Human CXCL14 (BRAK)
Aliases- Chemokine BRAK, MIP-2G, µmall-inducible cytokine B14
Formulation- Lyophilized from a 0.2 µm filtered solution containing 20mM Tris pH 8.5 and µm NaCl
Endotoxin Level- <1.0 EU/µg of recombinant protein as determined by the LAL method.
Storage Condition- 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° to +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.
