Product Summary for Human Osteocalcin Quantikine ELISA Kit

The Quantikine Human Osteocalcin Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Osteocalcin in cell culture supernates and EDTA plasma. It contains synthetic human Osteocalcin and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Osteocalcin showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human Osteocalcin.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components.

Recovery for Human Osteocalcin Quantikine ELISA Kit

The recovery of human Osteocalcin spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 105 98-120
EDTA Plasma (n=4) 102 80-116

Linearity

To assess the linearity of the assay, samples spiked with high concentrations of human Osteocalcin were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
