Mucosae-Associated Epithelial Chemokine ( CCL28 ) Rat Recombinant ( CCL28 Rat )

Data sheet

Formulation

The protein was lyophilized from a 0.2um filtered concentrated solution in 20mM PB, pH 7.4 and150mM NaCl.

Solubility

It is recommended to reconstitute the lyophilized MEC in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 95.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Description

MEC Rat Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 116 amino acids and having a molecular mass of 13.1kDa. The Rat MEC is purified by proprietary chromatographic techniques.

Protein Background

CCL28 is part of the subfamily of small cytokine CC genes. CCL28 shows chemotactic activity for resting CD4 or CD8 T cells and eosinophils. CCL28 binds to chemokine receptors CCR3 and CCR10. CCL28 is involved in the physiology of extracutaneous epithelial

Expression host

Escherichia Coli.

Synonyms

MEC, CCK1, SCYA28, MGC71902, CCL28, C-C motif chemokine 28, Small-inducible cytokine A28, Mucosae-associated epithelial chemokine, Protein CCK1.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized MEC although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution MEC should be stored at 4C between 2-7 days and for future use below -18C.For long term storage it is recommended to add a carrier
