Abstract

Methods are provided for a rapid, low cost approach to monitoring an amplification reaction. This includes monitoring the progress of isothermal or PCR amplification reactions to completion using pH-sensitive dyes that are either colored or fluorescent. Compositions are described that include a mixture of a DNA polymerase, deoxyribonucleotide triphosphate and a weak buffer of less than 1 mM Tris or equivalent or no buffer.
