Application: ORM1 (Orosomucoid 1), also named AGP1 (Alpha-1-acid glycoprotein 1) and AGP A, is an abundant plasma protein characterized by anti-inflammatory and immune-modulating properties. In human, two isoforms have been described, named ORM1 and ORM2. ORM1 is implicated in two main different functions: (1) as a lipocalin family member, it exerts a carrier activity especially for drug and lipid molecules; (2) being an acute phase protein (PMID: 23973664). ORM1 are increased in the patients with cancers, burnt injury or surgical operation (PMID: 10913518; PMID: 1646598). ORM1 could be a potential novel urinary biomarker for the early detection of chronic heart failure (PMID: 25215505).

This test kit is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The P21 ELISA kit is designed for the quantitative determination of P21 in samples of human and mouse origin. An antibody specific for P21 has been pre-coated onto the microwells. The P21 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody specific for P21 is added to detect the captured P21 protein. For signal development, horseradish peroxidase (HRP)-conjugated antibody is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450nm with the correction wavelength set at 630 nm.
