Abstract
We describe a rapid colorimetric method for the detection of PCR products. Color generation is complete within 5 min of mixing reagents with a PCR. The method is simple and does not require affinity capture steps or special labeling to be carried out. The color development can be monitored by eye or a simple spectrophotometer can be used to read sample absorbance. We demonstrate the method by its use in the amplification refractory mutation system (ARMS) analysis [C. R. Newton, A. Graham, L. E. Heptinstall, S. J. Powell, C. Summers, N. Kalsheker, et al.
