Clonogenicity assays. Assay Optimization (pre-validation): Assay optimization and pre-validation are experiments that determine how a range of matrix and sample elements, as well as assay conditions, effect assay parameters and assay performance. For detailed procedures and advice on assay development, the reader is referred to protocol books such as the NIH-supported e-book The Assay Guidance Manual [7] . Assays in drug discovery fall into two main categories: biochemical assays and cell-based assays. Biological assays are biochemical tools for analyzing biomolecules quantitatively or qualitatively. For the analysis of cell proliferation within tissue samples, or sometimes within cell culture, it is common to use antibodies to stain for the presence of Ki67, PCNA, or MCM-2. Biochemical assays run the gamut from routine ELISAs to micro-volume nucleic acid and protein quantification. Assay: An assay is an analysis done to determine: The presence of a substance and the amount of that substance. The summary table below highlights Enzo Life Sciences’ most common cellular assays that can be used to detect or measure cell proliferation, cell viability, apoptosis and autophagy. Biochemical assays are often the first type of assay used. Common applications of biological assays include 55 characterization of a biological or biotechnology product, stability testing, and lot 56 release.
