This gene encodes a secreted chemotactic protein that initiates chemotaxis via the ChemR23 G protein-coupled seven-transmembrane domain ligand. Expression of this gene is upregulated by the synthetic retinoid tazarotene and occurs in a wide variety of tissues. The active protein has several roles, including that as an adipokine, and is truncated on both termini from the proprotein. Sample Type: Serum, plasma and tissue homogenates Intended Use: For the quantitative determination of mouse retinoic acid receptor responder protein 2 (RARRES2) concentrations in serum, plasma and tissue homogenates. Sensitivity: 0.411ng/ml Range: 0.625-40ng/ml Specificity: This assay has high sensitivity and excellent specificity for detection of mouse RARRES2. No significant cross-reactivity or interference between mouse RARRES2 and analogues was observed. Test Principle: This BioAssay? employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for RARRES2 has been pre-coated o
