Abstract: Methods for determining quantities of nucleic acid sequences in samples undergoing amplification utilize amplification ratio estimates (R*) in operations to accurately perform absolute quantitation even when amplification factors for the target and control sequences undergoing amplification are different, time dependent or vary as a function of starting concentrations of nucleic acid sequences. These operations also take into account conversion efficiencies associated with the conversion of probes upon generation of target or control amplicons, but do not require the explicit calculation of such efficiencies. The operations also recognize that a preferred R* should be determined based on a preferred statistical criterion to improve quantitation. In addition, the use of standard samples having known starting concentrations of target and control sequences therein may enable accurate absolute quantitation without the explicit calculation of amplification ratio estimates.

Abstract: Primers and methods for adapter-mediated multiplex amplification of the IS6110 insertion element of Mycobacterium tuberculosis (M.tb) and the 16S ribosomal gene of Mycobacterium tuberculosis, useful for simultaneously detecting and/or identifying species of the M. tuberculosis complex and other clinically relevant Mycobacterium species. Multiplex Strand Displacement Amplification (SDA) is used in a single amplification reaction which is capable of simultaneously identifying M. tuberculosis and providing a screen for substantially all of the clinically relevant species of Mycobacteria. Also disclosed are methods for adapter-mediated multiplex amplification of multiple target sequences and a single internal control sequence for determination of sample efficacy or quantitation of the targets.
