"DEIA7442R is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the PIIANP (Type IIA Collagen N-Propeptide) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing PIIANP. The ELISA analytical biochemical technique of the DEIA7442R kit is based on PIIANP antibody-PIIANP antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect PIIANP antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, PIIANP. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%)."
