| Eotaxin is a CC chemokine that signals through the CCR3 receptor. It is produced by IFN-gamma-stimulated endothelial cells and TNF-activated monocytes. Eotaxin selectively chemoattracts eosinophils and, along with Eotaxin-2 and Eotaxin-3, plays a key role in the regulation of eosinophil recruitment in the asthmatic lung and in allergic reactions. Recombinant mouse Eotaxin is an 8.4kD protein containing 74 amino acid residues, including the four highly conserved cysteine residues present in CC chemokines. Amino Acid Sequence: HPGSIPTSCC FIMTSKKIPN TLLKSYKRIT NNRCTLKAIV FKTRLGKEIC ADPKKKWVQD ATKHLDQKLQ TPKP Biological Activity: Murine Eotaxin was found to induce chemotaxis of purified eosinophils at concentrations ranging between 10-100ng/ml. Storage and Stability: Lyophilized and reconstituted products are stable for 6 months after receipt at -20C. Reconstitute with sterile ddH2O, 0.1% BSA or HSA. Aliquot to avoid repeated freezing and thawing. Store at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. |
