RECOVERY
The recovery of Mouse PECAM1/CD31 spiked to three different levels in samples throughout the range of the assay in various matrices was evaluated.
LINEARITY
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of Mouse PECAM1/CD31 in various matrices were diluted with the Reference Standard & Sample Diluent to produce samples with values within the dynamic range of the assay.
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.
