摘要:
New electron transfer moiety labeled nucleic acid analogue probes are provided that can be used in methods for determining nucleic acids in a sample. The new probes can be prepared using novel monomer subunits in a chemical synthesis route. The nucleic acids can be determined by binding the probe molecules to the nucleic acid and inducing electron transfer within the complex formed. The occurrence of the electron transfer is determined as a measure of the nucleic acid.
摘要:
A cationic dye-borate anion compound represented by the formula: ##STR1## where D+ is a cationic dye moiety selected from the group consisting of cationic cyanine, carbocyanine, hemicyanine, rhodamine, and azamethine dyes; R.sup.1 is alkyl; and R.sup.2, R.sup.3, and R.sup.4 are aryl. Such cationic dye-borate anion compounds are useful photoinitiators of free radical addition reactions.
