Recombinant Human Eotaxin-2/CCL24

Description :
FAQ COA 已发表文献 Eotaxin-2 is a CC chemokine that signals through the CCR3 receptor. It is produced by activated monocytes and T lymphocytes. Eotaxin-2 selectively chemoattracts cells expressing CCR3, including eosinophils, basophils, Th2 T cells, mast cells, and certain subsets of dendritic cells. Additionally, Eotaxin-2 inhibits the proliferation of multipotential hematopoietic progenitor cells. The mature protein, which also includes a C-terminal truncation, contains 78 amino acid residues (92 amino acidresidues for the murine homolog, without C-terminal truncation). Eotaxin-2 contains the four conserved cysteine residues present in CC chemokines. Recombinant Human Eotaxin-2 is an 8.8 kDa protein containing 78 amino acid residues. Product Properties Synonyms CK-beta-6, MPIF-2, Small-inducible Cytokine A24 Accession O00175 GeneID 6369 Source E.coli-derived Human CCL24 protein,Vla27-Ala104. Molecular Weight Approximately 8.8 kDa AA Sequence VVIPSPCCMF FVSKRIPENR VVSYQLSSRS TCLKAGVIFT TKKGQQFCGD PKQEWVQRYM KNLDAKQKKA SPRARAVA Tag None Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. 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 peripheral blood eosinophils is in a concentration of 50-100 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.
