Procollagen III N-Terminal Propeptide (PIIINP) BioAssay(TM) ELISA Kit (Human)

This assay kit uses a competitive inhibition enzyme immunoassay technique for the in vitro quantitative measurement of PIIINP in human serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids. Sensitivity: 2.13ng/ml, Range: 4.94-400ng/ml, Specificity: This assay has high sensitivity and excellent specificity for detection of Procollagen III N-Terminal Propeptide (PIIINP). No significant cross-reactivity or interference between Procollagen III N-Terminal Propeptide (PIIINP) and analogues was observed. Precision: Intra-Assay: CV<10% , Inter-Assay: CV<12%, Test Principle: This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to PIIINP has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled PIIINP and unlabeled PIIINP (Standards or samples) with the pre-coated antibody specific to PIIINP. After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of PIIINP in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of PIIINP in the sample.
