WebAssay Sensitivity and Prozone Effect The assay sensitivity is relative to the characteristics of the positive controls used in the assay. In the present assay, the affinity-purified goat anti-mouse IgG antibody (PC) was used to evaluate the sensitivity of the assay. The assay sensitivity was tested on six occasions, performed by two analysts WebJan 1, 2010 · A standardized insulin assay will encourage research leading to measures of insulin sensitivity that will be practical for clinical care in a general population. Cutoff values of insulin concentrations and insulin sensitivity can then be determined that are associated with known magnitude of risk for developing type 2 diabetes. Additional ...
WebNov 4, 2024 · Successful generation of this anti-drug antibody positive control enabled Labcorp’s bioanalytical team/third party vendors to develop assays sensitive enough to detect sub-nanogram quantities of ADA responses. This enabled the regulatory review of the anti-sense therapeutic to advance to the next phase in clinical development. WebSensitivity is the lowest value of analyte in assay buffer that the assay can statistically differentiate from background. It is a calculated value, determined by comparing …
