C-C motif chemokine 14 (CCL14), recombinant human

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 20-93aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: TKTESSSRGP YHPSECCFTY TTYKIPRQRI MDYYETNSQC SKPGIVFITK RGHSVCTNPS DKWVQDYIKD MKEN. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week. Relevance: Has weak activities on human monocytes and acts via receptors that also recognize MIP-1 alpha. It induced intracellular Ca2+ changes and enzyme release, but no chotaxis, at concentrations of 100-1,000 nM, and was inactive on T-lymphocytes, neutrophils, and eosinophil leukocytes. Enhances the proliferation of CD34 myeloid progenitor cells. The processed form HCC-1(9-74) is a chotactic factor that attracts monocytes eosinophils, and T-cells and is a ligand for CCR1, CCR3 and CCR5. Reference: HCC-1, a novel chemokine from human plasma.Schulz-Knappe P., Maegert H.-J., Dewald B., Meyer M., Cetin Y., Kubbies M., Tomeczkowski J., Kirchhoff K., Raida M., Adermann K., Kist A., Reinecke M., Sillard R., Pardigol A., Uguccioni M., Baggiolini M., Forssmann W.-G.J.
