Parathyroid Hormone Related Protein (PTHrP) BioAssay(TM) ELISA Kit (Human)

Sample Type:, Serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids, Intended Use: The kit is a competitive inhibition enzyme immunoassay technique for the in vitro quantitative measurement of PTHrP in human serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids. Sensitivity: 4.87pg/ml, Range: 12.35-1000pg/ml, Specificity: This assay has high sensitivity and excellent specificity for detection of Parathyroid Hormone Related Protein (PTHrP). No significant cross-reactivity or interference between Parathyroid Hormone Related Protein (PTHrP) 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 PTHrP has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled PTHrP and unlabeled PTHrP (Standards or samples) with the pre-coated antibody specific to PTHrP. 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 PTHrP in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of PTHrP in the sample.
