Objective:
Evaluation of the use of short probes as a detection system in real-time PCR.
Design And Method:
Comparison of results obtained with hybridization probes with and without locked nucleic acid (LNA) residues in the detection of fetal DNA in maternal serum.
Results:
The use of chimeric LNA/DNA probes led to a slight but significantly higher level of sensitivity as well as a higher level of fluorescence signal.
Conclusion:
Chimeric LNA/DNA probes offer an interesting alternative detection method in real-time PCR.
