Additional sequence informationMonocyte Chemotactic Protein-1 Rat Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 125 amino acids and having a molecular mass of 14.1 kDa.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Biological activityBiological Activity: ED50 = 1.0-10.0 ng/mL. The biological activity was determined by measuring the dose dependent chemotaxis with human THP-1 cells. The optimal concentration should be determined for each specific application by an initial dose-response assay.
% SDS-PAGE. Purified by proprietary chromatographic techniques.
Additional notesFor long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

FunctionChemotactic factor that attracts monocytes and basophils but not neutrophils or eosinophils. Augments monocyte anti-tumor activity. Has been implicated in the pathogenesis of diseases characterized by monocytic infiltrates, like psoriasis, rheumatoid arthritis or atherosclerosis. May be involved in the recruitment of monocytes into the arterial wall during the disease process of atherosclerosis.
Sequence similaritiesBelongs to the intercrine beta (chemokine CC) family.
Post-translational modificationsProcessing at the N-terminus can regulate receptor and target cell selectivity. Deletion of the N-terminal residue converts it from an activator of basophil to an eosinophil chemoattractant.
