Recombinant Human MEC/CCL28 重组人MEC/CCL28

Description :
FAQ COA 已发表文献 MEC is a secreted CC chemokine expressed primarily by epithelial cells of the bronchioles, salivary gland, mammary gland and colon. MEC signals through the CCR10 receptor, and chemoattracts resting CD4, CD8 T-cells and eosinophils. MEC contains six cysteines, including the four highly conserved cysteine residues present in CC chemokines. Recombinant Human MEC is a 12.3 kDa protein containing 108 amino acid residues. Product Properties Synonyms CCK1 Accession Q9NRJ3 GeneID 56477 Source E.coli-derived Human MEC/CCL28 protein,Ser20-Try172. Molecular Weight Approximately 12.4 kDa.

Purity > 97% by SDS-PAGE and HPLC analyses. Biological Activity Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human lymphocytes is in a concentration range of 1.0-10.0 ng/mL Endotoxin Formulation Lyophilized from a 0.2 m filtered concentrated solution in 20 mM PB, pH 7.4, 130 mM NaCl. Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at -20C. Further dilutions should be made in appropriate buffered solutions.
