LATE-PCR and allied technologies: real-time detection strategies for rapid, reliable diagnosis from single cells.

Abstract

Accurate detection of gene sequences in single cells is the ultimate challenge of PCR sensitivity. Unfortunately, commonly used conventional and real-time PCR techniques are often too unreliable at that level to provide the accuracy needed for clinical diagnosis. Here we provide details of Linear-After-The-Exponential-PCR (LATE-PCR), a method similar to asymmetric PCR in the use of primers at -different concentrations, but with novel design criteria to insure high efficiency and specificity. LATE-PCR increases the signal strength and allele discrimination capability of oligonucleotide probes such as molecular beacons and reduces variability among replicate samples. The analysis of real-time kinetics of LATE-PCR signals provides a means for improving the accuracy of single-cell genetic diagnosis.
