Acridine ester is one of the most sensitive chemiluminescence reagents. Conventional acridine ester has 6 different groups, acridine ester NSP-SA-NHS, CAS number is 199293-83-9, product color is yellow It is in the form of powder. When it is used, it is configured to dissolve in contact with alkaline hydrogen peroxide, without the catalysis of enzymes, it can emit light by itself, because the contact between hydrogen peroxide and acridine ester will change the two components, which will produce luminescence. , collecting this photon can be used to label the detection compound.
