High-throughput screening assay used in pharmacognosy: Selection, optimization and validation of methods of enzymatic inhibition by UV-visible spectrophotometry
Journal Title: Journal of Pharmacy & Pharmacognosy Research - Year 2014, Vol 2, Issue 1
Abstract
In research laboratories of both organic synthesis and extraction of natural products, every day a lot of products that can potentially introduce some biological activity are obtained. Therefore it is necessary to have in vitro assays, which provide reliable information for further evaluation in in vivo systems. From this point of view, in recent years has intensified the use of high-throughput screening assays. Such trials should be optimized and validated for accurate and precise results, i.e. reliable. The present review addresses the steps needed to develop and validate bioanalytical methods, emphasizing UV-Visible spectrophotometry as detection system. Particularly focuses on the selection of the method, the optimization to determine the best experimental conditions, validation, implementation of optimized and validated method to real samples, and finally maintenance and possible transfer it to a new laboratory.
