The assay methods covered include the use of different …

Assay: An assay is an analysis done to determine: The presence of a substance and the amount of that substance. Thus, an assay may be done for example to determine the level of thyroid hormones in the blood of a person suspected of being hypothyroid (or hyperthyroid). The biological or pharmacological potency of a drug.

The ADP-Glo™ Kinase Assay measures ADP formed from a kinase reaction. The ADP is converted into ATP, which is used to generate light in a luciferase reaction. The luminescence generated correlates with kinase activity. The assay is well suited for measuring the effects of chemical compounds on the activity of many purified kinases, making it ...

This eBook is a comprehensive, crucial resource for investigators optimizing assays to evaluate collections of molecules with the overall goal of developing probes that modulate the activity of biological targets, pathways or cellular phenotypes. Such probes might be candidates for further optimization and investigation in drug discovery and development.

A tube formation assay is performed by first seeding single cells, and then observing and imaging the tube formation over time. Several readouts can be imaged and analyzed over time, such as tube length and the number of loops. Typically, tubes are formed within a few hours, making the tube formation assay a rapid tool for angiogenesis ...

Copper-based total protein quantification. The BCA Protein Assay is a popular method for colorimetric detection and quantitation of total protein. Pierce BCA Protein Assays have a unique advantage over the Coomassie dye–based assays (Bradford)–they are compatible with samples that contain up to 5% surfactants (detergents), and are affected ...

assay: [verb] to analyze (something, such as an ore) for one or more specific components. to judge the worth of : estimate.

Bruton's tyrosine kinase or BTK, is an enzyme that plays a role in the functionality and maturation of B cells. The BTK pathway has implications for a number of autoimmune disorders including isolated growth hormone deficiency type III and rheumatoid arthritis. The BTK Assay Kit is designed to measure BTK activity for screening and profiling ...
