Zantac, Clarinex, Zyprexa) • GPCRs are proteins with 7 transmembrane domains SPEAD was comparable in performance to ACE for the biotherapeutic drugs tested, but suffers the disadvantage of being reagent-intensive. Introduction:- Bioassay is defined as estimation or determination of concentration or potency of physical, chemical or biological agents by means of measuring and comparing the magnitude of the response of the test with that of standard over a suitable biological system under standard set of conditions. If the organism is susceptible to the antibiotic in this test, it is highly likely that it will also be killed off when the antibiotics interact with the microbe in the blood stream. Grinding equipment may be difficult to clean, raising potential contamination/hygiene issues. Biological assays or biological standardizations or simply bioassays are methods used for estimation of the potency of substances by observing their pharmacological effects on living animals (in vivo) or isolated tissues (in vitro) and comparing the effect of these substances of unknown potency to the effect of a standard. [3] A large number of different methods of measuring the concentrations of substrates and products exist and many enzymes can be assayed in several different ways. A toxicology screen is a test that determines if someone has used certain legal or illegal drugs. Examples – contractions of muscle, blood pressure, blood sugar concentrations, etc. KINOMEscan and KiNativ assays measure interactions of kinase inhibitors with kinases. An assay is a form of biological experiment; but the interest lies in comparing the potencies of treatments on an agreed scale, instead of in comparing the magnitude of effects of different treatments. Every type of protein assay is adversely affected by substances of one sort or another. Generally, biochemists use hundreds of biochemical assays to analyze biomolecules qualitatively or quantitatively. The method selected should be reliable, sensitive, and reproducible and should minimize errors due to biological variation and methodology. 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). A cell-based assay can help determine if the drug-target interaction is occurring and if so, what specific cells and signaling pathways are engaged using functional and reporter readouts.
