Efficiency of polymerase chain reaction processes: A stochastic model [PDF]

open access: yes, 2006
A stochastic model for the efficiency of polymerase chain reaction (PCR) processes is presented. The model is based on the assumption that the i’th nucleotide incorporation on the DNA template takes τi seconds, where τi has an exponential distribution ...

On joint maximum-likelihood estimation of PCR efficiency and initial amount of target [PDF]

open access: yes, 2007
We consider the problem of estimating unknown parameters of the real-time polymerase chain reaction (RTPCR) from noisy observations. The joint ML estimator of the RT-PCR efficiency and the initial number of DNA target molecules is derived.

Semi-quantitative digital analysis of polymerase chain reactionelectrophoresis gel: Potential applications in low-income veterinary laboratories [PDF]

open access: yesVeterinary World, 2016
Aim: The interpretation of conventional polymerase chain reaction (PCR) assay results is often limited to either positive or negative (non-detectable). The more robust quantitative PCR (qPCR) method is mostly reserved for quantitation studies and not a ...

Computing by polymerase chain reaction [PDF]

open access: yesMathematical Biosciences, 2008
A mathematical notation is introduced to represent, at a symbolic level, different mechanisms of DNA recombination, and a 'PCR lemma' is proven by analytically describing the combinatorial properties of the polymerase chain reaction process. This approach led to the discovery of novel techniques, based on a form of PCR which we called cross pairing PCR
