【English Name】: [(4-Chlorophenyl)thio](10-methyl-9(10H)-acridinylidene)-methanol 1-(dihydrogen phosphate) disodium salt 【Chemical Name】: 9-(4'-Chlorophenylthiophosphoryloxymethylene)-10-methyl-9,10-dihydroacridine disodium salt 【Purity】: ≥98% 【Package Specification】: 5g/bottle 【Production Batch】: 200g Application: This substrate reagent (APS-5), when mixed with alkaline phosphatase (ALP), undergoes immediate decomposition upon hydrolysis of the phosphate group by ALP, releasing photons. Within specific concentration ranges of alkaline phosphatase, the number of photons released is proportional to the concentration of ALP in the solution, making it suitable for quantitative detection of alkaline phosphatase. It is used in the production of (magnetic particle) chemiluminescent antibody detection kits.
