Intra-assay Precision (Precision within an assay): CV%<8% | ||||||||||||||||||||||||||||||||||||||||||||||||||
Three samples of known concentration were tested twenty times on one plate to assess. | ||||||||||||||||||||||||||||||||||||||||||||||||||

To assess the linearity of the assay, samples were spiked with high concentrations of human IL-18BP in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. | |||||||||

Review: I used CSB-E13687h to detect IL-18BP in plasma samples from patients with systemic lupus erythematosus. The OD range of standard drug was 0.06-1.75. The OD value of plasma samples ranges from 0.8-1.5, and the R square of the standard curve is about 0.99. The sample concentration range calculated according to the standard curve is 8-17ng/mL, which is in line with the expected results.
