Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS. Endotoxin Level <0.2 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human Hemofiltrate CC Chemokine-1/CCL14 (rHuHCC-1/CCL14) to 100 µg/mL using ddH2O. Storage & Stability Lyophilized recombinant Human Hemofiltrate CC Chemokine-1/CCL14 (rHuHCC-1/CCL14) is stored at -20°C. After reconstitution, it is stable at 4°C for 2 weeks or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background Human Hemofiltrate CC Chemokine-1/CCL14 (HCC-1) is expressed constitutively in several normal tissues (spleen, liver, skeletal and heart muscle, gut, and bone marrow), and is present at high concentrations (1-80 nM) in plasma. HCC-1 has weak activities on human monocytes and acts via receptors that also recognize MIP-lot. It induces intracellular Ca2+ changes and enzyme release, but no chemotaxis, at concentrations of 100-1,000 nM, and is inactive on T lymphocytes, neutrophils, and eosinophil leukocytes. In addition, HCC-1 enhances the proliferation of CD34+ myeloid progenitor cells. It is as effective as MIP-1α, but about 100-fold less potent[1]. CCL14 regulate extracellular matrix and adhesion molecules in the trophoblast[2]. |
