Abstract:
Disclosed is a method of determining an initial concentration of a target nucleic acid within a sample using real-time nucleic acid amplification data. Amplification efficiencies of the target nucleic acid with respect to amplification time are obtained from signals of amplified products, and an amplification efficiency function with respect to amplification time is formulated employing the amplification efficiencies.
