Product Summary
The Quantikine Human BDNF Immunoassay is a 3.5 hour solid phase ELISA designed to measure human BDNF in cell culture supernates, serum, and plasma. It contains recombinant human BDNF expressed in Sf 21 cells and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant BDNF accurately. Results obtained measuring natural human BDNF showed dose-response curves that were parallel to the standard curves obtained using the recombinant Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural human BDNF.
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, five samples containing or spiked with high concentrations of BDNF in various matrices were diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
