The second edition of the report “Assay Development and Technologies” from Research and Markets Ltd. provides an assessment of the capabilities, strengths, weaknesses and expectations of assays and assay technologies. Designed to assist biotechnology and pharmaceutical professionals in their selection of appropriate assays, the report includes additional content to reflect advances in the technology. Along with assay multiplexing and applications of whole-cell assays, it considers the importance of high-content, cell-based assays in drug discovery and candidate development. A new appendix devoted to fluorescent proteins discusses assay applications and properties of the “reporter” molecules. An understanding of the business aspects of assay development is important for implementing the procedures described. The report is available electronically and in print, at the price of $1264, 7958.
