Huateng Pharma Develops A novel chemiluminescent Substrate APS-5

APS-5 (CAS No: 193884-53-6) is a chemiluminescent substrate based on 9,10-dihydroacridine, mainly used to detect compounds with alkaline phosphatase AP conjugates. At present, chemiluminescence immunity has become the mainstream of immune market in China. APS-5 has a wide range of applications in chemiluminescence immunity platform due to its ultra-high sensitivity, short color development time and long fluorescence duration.

“APS-5 has been used as a luminescent probe in gene chip studies, and its application in homogeneous alkaline phosphatase assays has shown ultra-high sensitivity”, said the Marketing Chief of Huateng Pharma. “Now we have developed APS-5, Huateng Pharma can provide APS-5 with high quality and reasonable price.”

In the surfactant solution, the concentration of surfactant reaches a certain value, the surfactant molecules will form a variety of ordered assemblies called micelles. Micellization or micelle formation is a very important fundamental property of surfactant solutions, and a number of important interfacial phenomena are related to micelle formation. The concentration at which the surfactant forms micelles in solution is called Critical Micelle Concentration (CMC). Micelles are not fixed spherical shapes, but are extremely irregular and dynamically changing. Under certain conditions, surfactants may also appear in an anti-micellar state.

Product Information of APS-5

Product Name: APS-5

Reaction Mechanism of APS-5

When APS-5 is mixed with alkaline phosphatase (ALP), the alkaline phosphatase phosphate is hydrolyzed and the substrate immediately undergoes a decomposition reaction to release photons, and the number of photons released is proportional to the concentration of alkaline phosphatase in the solution within a specific alkaline phosphatase concentration range, so it can be used for the quantitative detection of alkaline phosphatase.

Advantages of APS-5

1. High sensitivity - can reach 10 of 19 times molar concentration

2. High luminous intensity - can reach the luminous peak in a short time (within 10s)

3. Continuous and stable luminescence - its luminescence process is not affected by temperature within 25-35 ℃, no temperature control is required

4. There is a good linear relationship between the concentration of alkaline phosphatase and the number of photons released

5. The blank luminous value is low

Application areas of APS-5

1. Chemiluminescence platform (alkaline phosphatase system)

2. Quantitative detection of alkaline phosphatase

3. As a luminescent probe for gene chip
