Jf. Sallstrom et al., PITFALLS OF IN-SITU POLYMERASE CHAIN-REACTION (PCR) USING DIRECT INCORPORATION OF LABELED NUCLEOTIDES, Anticancer research, 13(4), 1993, pp. 1153-1153
False positivity is reported of in situ PCR reactions in a direct inco
rporation assay with digoxigenin-labelled dUTP. It is recommended that
in situ hybridization with specific labelled probe replaces the direc
t incorporation method for the detection of in situ PCR amplicon.
