Intra-assay Precision (Precision within an assay): CV%<8%

Three samples of known concentration were tested twenty times on one plate to assess.

Inter-assay Precision (Precision between assays): CV%<10%

Three samples of known concentration were tested in twenty assays to assess.

To assess the linearity of the assay, samples were spiked with high concentrations of mouse IL-12/P70 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
