Prolonged chemiluminescence

Реферат: ABSTRACT OF THE DISCLOSURE A chemiluminescence process comprising the contacting of a chemiluminescence precursor, an oxidant, an enzyme and a nitrogen compound selected from the group consisting of ammonia and a water-soluble organic amine. The reaction of such process can be used in detection of nucleic acid hybrids, antibodies, antigens and peroxidase enzymes and in producing light. Another chemiluminescence process comprises the contacting of a chemiluminescence precursor, an oxidant, an enzyme, a chemiluminescence enhancer and a nitrogen compound selected from the group consisting of ammonia and water-soluble organic amines. The reaction of such process can be used in detection of nucleic acid hybrids, antibodies, antigens and peroxidaze enzymes and in producing light. A nucleic acid probe capable of participating in a chemiluminescent reaction comprising a defined nucleic acid sequence, the sequence being linked to any one of a. a chemiluminescence precursor, b. a chemiluminescence enhancer, and c. an enzyme the remaining two of (a), (b) and (c) not linked to the sequence being in a mixture of the linked sequence. A method for determining a particular single stranded polynucleotide sequence in a test medium, comprising the steps of: (a) combining the test medium with a polynucleotide probe having a base sequence substantially complementary to the sequence to be determined, (b) labeling either the resulting hybrids or probe which has not hybridized with the sequence to be determined with one of the participants in an enhanced chemiluminescent reaction involving a chemiluminescent precursor, an enzyme, an oxidant, and a chemiluminescence enhancer, (c) initiating such chemiluminent reaction with the labeled hybrid or probe, and (d) detecting the resulting light emission.
