Screening / Bioassay

Screening / Bioassay

A bioassay is a biological testing procedure for estimating the concentration of an active substance in a formulated product or bulk material. A bioassay provides results on the biological activity of a substance. Over the last decade bioassays and biostatistical analysis have become more important in effectively controlling the quality of agrochemicals development and manufacturing.
The general approach of most bioassays is to perform a dilution assay, which measures the biological responses at several doses. A key assumption of a dilution assay is that the active component follows the same principle of activity in standard and in sample preparation. In this case the unknown preparation may in theory be derived by diluting it with inert components or by concentrating the bulk solution.
