relative to true PCR, since it relies on the action of a DNA ligase, which is typically less efficient than a DNA polymerase. LDR achieves linear amplification rather than exponential amplification as in LCR [49]. die Ligase Cycling Reaction (LCR) und wird daher in dieser Arbeit verwendet. Thermostable ligase (Q) will only ligate primers that are perfectly complementary to their target sequence and hybridize directly adjacent to each other (as shown with L. monocytogenes, left).

LCR involves the use of two pairs of probes, each pair being complementary to a strand of the denatured target DNA. Ligase Detection Reaction (LDR) LDR is a modified LCR technique where only two oligonucleotides, instead of 4, bind adjacently on one target strand. As you know, DNA is double-stranded and connected by matching base pairs, kind of like two sections. Performing LCR in microchips remains a challenge because of the inhibitory effect of the internal surfaces of silicon-glass microchips.
