Purpose of biological assay Biological assays are methods for the estimation of nature, constitution, or potency of a material (or of a process) by means of the reaction that follows its application to living matter. Biological Assay is used to maintain quality of the substance. A biological assay, strictly speaking, is an attempt to find out from a trial with living creatures of some particular species how much of a given substance is present, per cent., weight or volume, in a preparation containing the substance. It supersedes the biological assay features of the PLA 2.x system. Sets of two occur where each test animal is used twice, as in the assays of Tubocurarine Chloride Injection and Insulin Injection. Significant non-parallelism indicates that the antibody or antigen discriminates between test and standard, and the results are not valid. It determines the biological activity of a substance. Three types of bioassay are Quantal, Graded, Effect produced in confined period. andthat ofthe test solutions addedto the bath usually 1 c.c. Recently `biotechnology' has also been considered for bioassay. Biological Assay of Glucagon in Rabbits F. TA]aDING, P. INIELSEN, B. KEISE!a-NIELSEN and AA.V. Thus the entire group when completed will consist of five USP General 14 Chapters. VII, 508 S., £ 19 net If the confidence interval is more than 0.082, which corresponds at P = 0.95 to confidence limits of about ±10% of the com-puted potency, repeat the assay until the combined data If g≥1, the denominator is not significantly different from of the two or more assays, redetermined as described in 0 and the formula does not work. Biological assays (also called bioassays) are an integral part of the quality assessment required for the manufacturing and marketing of many biological and some non-biological drug products. which biological assays are required are in such cases expressed in terms of an equivalent weight of the pure substance. 11 biological assays allows both greater focus and clarity and the opportunity to expand on 12 issues.

Predicting the outcome of biological assays based on high-throughput imaging data is a highly promising task in drug discovery since it can tremendously increase hit rates and suggest novel chemical scaffolds. for Sensitive Point-of-Care Biological Test Yuhui Dong,1,5 Xiaoqian Tang,2,5 Zhaowei Zhang,2,* Jizhong Song,1,4 Tianchao Niu,1 Dan Shan,3 and Haibo Zeng1,6,* SUMMARY Quantitative fluorescence immunoassay is a vital and convenient method in point-of-care (POC) testing for food safety and clinical healthcare.
