[Application with single-stranded probes in randomized terminal linker-dependent PCR].
OBJECTIVE: Preparing single-stranded (ss) probes in place of double-stranded (ds) probes to improve the hybridization efficiency and specificity of randomized terminal linker-dependent PCR (RDPCR). METHODS: Using asymmetric PCR and single-primer PCR to prepare ss probes of extron 7 of p53 gene in rat, then comparing the results hybridized with ss probes and ds probes. RESULTS: Preparation of ss probes by asymmetric PCR and single-primer PCR gets success. Hybridization results showed that the ss probes could get better signals and less noise than ds probes. CONCLUSION: In comparison with ds probes, the application of ss probes can increase the hybridization sensitivity and specificity of RDPCR.
