Performance Data
Typical Data
Please refer to DS document for the assay protocol.

For each experiment, a standard curve needs to be set for each micro-plate, and the specific OD value may vary depending on different laboratories, testers, or equipments. The following example data is for reference only.
Dilution Linearity
To assess the linearity of the assay, samples spiked with high concentrations of Cas9 nuclease were serially diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.

Intra-Assay Statistics
Three samples of known concentration were tested ten times on one plate to assess intra-assay precision.

Inter-Assay Statistics
Three samples of known concentration were tested in three separate assays to assess inter-assay precision.

Recovery
Three Cas9 nuclease with different concentrations were tested to calculate the recovery rate.
