One-step fluoroscence HTS assays are getting faster, cheaper, smaller, and more sensitive. Recent advances in genomics, combinatorial chemistry, and laboratory automation have placed great pressure on those who screen new drug candidates.
Faster assays make good financial sense.
Screening materials are a significant fraction of the total screening costs. In many cases, the costs of the chemical and biological reagents can add up to three-quarters of the total screening costs. Miniaturization is an attractive way to hold down material costs. Also, miniaturized tests can help reduce the need for laboratory space. Automation can help with speed and reproducibility of results.
