Bioassay system

Bioassay System BioAssay Systems scientists have over 30 years of extensive experiences in assays and services. Our services encompass a wide variety of custom projects. BioAssay Systems provides highest possible quality and the most convenient bioassays which is non-radioactive formats, and safe for health. Alkaline phosphatase  (ALP) catalyzes the hydrolysis of phosphate esters in an alkaline environment, resulting in the formation of an organic radical and inorganic phosphate. In mammals, this enzyme is found mainly in the liver and bones. Marked increase in serum ALP levels, a disease known as hyperalkalinephosphatasemia, has been associated with malignant biliary obstruction, primary biliary cirrhosis, primary sclerosing cholangitis, hepatic lymphoma and sarcoidosis. Simple, direct and automation-ready procedures for measuring ALP activity in serum are becoming popular in Research and Drug Discovery.

ACETYLCHOLINESTERASE  (EC 3.1.1.7, AChE), also known as RBC cholinesterase, is found primarily in the blood and neural synapses. Low serum cholinesterase activity may relate to exposure to insecticides or to one of a number of variant genotypes. AChE catalyzes the hydrolysis of the neurotransmitter acetylcholine into choline and acetic acid, a reaction necessary to allow a cholinergic neuron to return to its resting state after activation. Cholinesterase levels of cells and plasma are used as a guide in establishing safety precautions relative to exposure and contact, as well as a guide in determining the need for workers to be removed from areas of contact with the organic phosphate insecticides. Simple, direct and automation-ready procedures for measuring AChE activity are very desirable. BioAssay Systems QuantiChrom™ Acetylcholinesterase Assay is based on an improved Ellman method,in which thiocholine produced by the action of acetylcholinesterase forms a yellow color w...
