详细介绍

Eotaxin Mouse/ 重组小鼠嗜酸性粒细胞趋化因子

产品编号：CHM-308
产品规格：5μg/20μg/1mg

Synonyms	Small inducible cytokine A11, CCL11, Eosinophil chemotactic protein, chemokine （C-C motif） ligand 11, SCYA11.
Introduction	Chemokine （C-C motif） ligand 11 （CCL11） is a small cytokine belonging to the CC chemokine family that is also known as eotaxin. CCL11 selectively recruits eosinophils by inducing their chemotaxis, and therefore, is implicated in allergic responses. The effects of CCL11 are mediated by its binding to a G-protein-linked receptor known as a chemokine receptor. Chemokine receptors for which CCL11 is a ligand include CCR2, CCR3 and CCR5. The gene for human CCL11 （scya11） is encoded on three exons and is located on chromosome 17.
Description	Eotaxin Mouse Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 74 amino acids and having a molecular mass of 8403.2 Dalton. The CCL11 is purified by proprietary chromatographic techniques.
Source	Escherichia Coli.
Physical Appearance	Sterile Filtered White lyophilized （freeze-dried） powder.
Formulation	Lyophilized from a concentrated （1mg/ml） solution in water containing no additives.
Solubility	It is recommended to reconstitute the lyophilized Eotaxin in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
Stability	Lyophilized Eotaxin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CCL11 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Please prevent freeze-thaw cycles.
Purity	Greater than 95.0% as determined by（a） Analysis by RP-HPLC. （b） Analysis by SDS-PAGE.
Amino acid sequence	The sequence of the first five N-terminal amino acids was determined and was found to be His-Pro-Gly-Ser-Ile.
Biological Activity	The Biological activity was determined by measuring the dose dependent phosphorylation of ERK1 and ERK2 in CCR3 transfected 293 cells. Significant ERK phosphorylation is observed with >100 ng/ml of recombinant mouse eotaxin.
Usage	Prospec's products are furnished for LABORATORY RESEARCH USEONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
