The next section describes the utilization of //PLC for different applications of interest in the pharmaceutical industry. The part discusses the instrumentation employed for these applications, followed by the results of detailed characterization studies. The next part focuses on particular applications, highlighting results from the high-throughput characterization of ADMET and physicochemical properties (e.g., solubility, purity, log P, drug release, etc.), separation-based assays (assay development and optimization, real-time enzyme kinetics, evaluation of substrate specificity, etc.), and sample preparation (e.g., high-throughput clean-up of complex samples prior to MS (FIA) analysis). 

Feeding assays Assays were performed with diets placed between two layers of Parafilm M (23). The diet was as described (24). When young aphids were used (survival and feeding deterrence assays) they were 3rd and 4th-instar nymphs.

It gave a positive result in one out of seven assays for reverse mutation. However, it caused aneuploidy in two out of three assays. Assays for forward mutation or genetic crossing-over in Aspergillus nidulans gave completely negative results, as did a forward mutation assay in Schizosaccharomyces pombe.

IC assays are divided into two groups on the basis of receptor principle. Assays which make use of a receptor for the Fc portion of immunoglobulin in IC are the ClqBA, SBA, and the MRF assay. Assays which make use of a receptor for complement components fixed to IC are the BCA and the Raji assay.

One example is the known interference by reducing compounds that affect the chemical conversion of substrate to a colored indicator. This is especially true for the tetrazolium assays (Ulukaya, Colakogullari, and Wood 2004 Chakrabarti et al. 2000 Pagliacci et al. 1993 Collier and Pritsos 2003). The growing list of interfering compounds includes ascorbic acid and sulfhydryl reagents such as glutathione, coenzyme A, dithiothreitol, etc. Similar interferences by compounds that affect the oxidation and reduction chemistry of cells are likely to cause artifacts with the resazurin reduction assay. Assays that measure markers of metabolism also can be influenced by the pH of the culture medium and other factors that may stimulate or stress the metabolic rates of cells.

B. The retention time of the major peak in the chromatogram of the Assay Preparation corresponds to that in the chromatogram of the Standard Preparation as obtained from the Assay. Assay Not less than 50.0%, by weight, of D-maltitol (C12H24OH), calculated on the anhydrous basis, and not more than 8.0% of D-sorbitol (C6U 406), calculated on the anhydrous basis. 

Note 6 (Assay) Assay requirements are specified as minimum values (unless a range of assay values is given) and are stated in weight percent unless otherwise indicated. References to assay methods are indicated by citations in parentheses, e.g., (M-1 a), to methods provided under Test Methods for Flavor Chemicals. 

The following enzymic reactions were observed. Dialyzed extracts of S. glebosus catalyzed the conversion of mt/o-[U-,4C]inositol (31, Scheme 12) to aminodeoxy-scyHo-[U-14C]inositol (33) when both NAD+ and an amino donor were provided. NAD+ was presumably required in order to form keto-sct/Wo-[U-14C]inositol (32), and the amino donor (for example, L-glutamine) was required in order to convert 32 into 33. The transamination reaction was confirmed in a separate assay. Assays for reactions H and I (see Scheme 12) with S. glebosus were negative. 

Selection of antibody is a critical point. Traditionally, a high affinity has been preferred, since it gives high sensitivity in the assay. Assays normally are deadend binding reactions.
