We report a rapid and highly versatile one-step single tube method for gene
amplification and detection using a non-radiolabelled probe. The technique
requires nylon on which a third primer has been immobilized that acts as a
probe and digoxigenin-labelled-dUTP added to the conventional PCR mixture.
After PCR amplification the membrane-impregnated probe is labelled with di
g-11-dUTP that serves to confirm the identity of the PCR product.
