Specificity
Natural and recombinant human PCSK9. This assay recognizes free and LDLR-bound PCSK9.

Interference
No significant interference observed with available related molecules.
Product Summary
The Quantikine Human PCSK9 immunoassay is a 4.5 hour solid phase ELISA designed to measure PCSK9 in cell culture supernates, cell lysates, serum, and plasma. It contains NS0-expressed recombinant human PCSK9 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural PCSK9 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 PCSK9.
Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision

Linearity
To assess the linearity of the assay, samples containing high concentrations of PCSK9 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
