Recombinant Human TECK/CCL25 重组人TECK/CCL25

Description :
FAQ COA 已发表文献 TECK is a CC chemokine, specifically expressed by thymic stromal cells, and signals through the CCR9 receptor. TECK is chemotactic towards activated macrophages, thymocytes and dendritic cells. Recombinant Human TECK is a 14.3kDa protein containing 127 amino acid residues, including the four conserved cysteine residues present in CC chemokines. Product Properties Synonyms TECK, CCL25, SCYA25, Ckb15 Accession O15444 GeneID 6370 Source E.coli-derived Human CCL25 protein,Glu24-Leu150.

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 monocytes is in a concentration range of 1.0-10 ng/ml. Endotoxin Formulation Lyophilized from a 0.2 m filtered concentrated solution in 20 mM PB, pH 7.4, 150 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.
