BioAssay Systems provides highest possible quality and the most convenient bioassays which is non-radioactive formats, and safe for health. QuantiFluo™ ALP Reagent is a stable 4-methylumbelliferyl phosphate (MUP) liquid substrate reagent formulated for detecting alkaline phosphatase ALP, e.g. in ELISA. This single reagent produces a highly fluorescent product ( λ ex/em = 360/450 nm) when  dephosphorylated by ALP. The fluorescent product can also be visualized under a UV light.

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...
