Description_x000D_ General description_x000D_ Chemerin, which is also known as retinoic acid receptor responder 2 (RARRES2), is a chemoattractant expressed in white adipose, liver and lung tissues. It is an immunomodulating factor. The protein is a ligand for the G-protein coupled receptor known as ChemR23 (or chemokine-like receptor-1), which is expressed mainly on dendritic cells, macrophages and some adipocytes. The gene encoding it is localized on human chromosome 7q36.1. Recombinant human Chemerin, produced in Escherichia.coli, is a non-glycosylated protein containing 138 amino acids and having a total molecular mass of 16kDa._x000D_ Biochem/physiol Actions_x000D_ Chemerin activates chemerin-like receptor 1 (CMKLR1) and stimulates chemotaxis in macrophages, natural killer cells and immature dendritic cells. It is also involved in the activation of extracellular signal-regulated kinases, stimulation of blood vessel formation, migration and invasion._x000D_ Physical form_x000D_ Lyophilized from 0.2% TFA._x000D_ Reconstitution_x000D_ Centrifuge the vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile H?O to a concentration of 0.1mg/ml, which can be further diluted into other aqueous solutions.
