A method of analysing a polynucleotide target involves incubating the target with an oligonucleotide probe, generally an array of immobilized oligonucleotide probes, to form a duplex, and using ligase or polymerase to extend one chain of the duplex. Each of these polymerase chain reaction steps is repeated 30-40 times (cycles). Newly ligated oligonucleotides become targets in subsequent cycles so logarithmic amplification occurs. Then 30 thermal cycles (80 C for 5 s and 40 C for 1 min) were performed. This enzyme belongs to the family of ligases, to be specific those forming carbon-oxygen bonds . We identified it from honorable source. For each one, a set of four probes is used simultaneously to amplify the putative sequence if it is present in the sample.

A DNA amplification technique based upon the ligation of OLIGONUCLEOTIDE PROBES. During step 3, the 3-OH end of a second DNA strand attacks the 5-PO 4, to release AMP and generate the ligated DNA product. Cullin; The three-step reaction catalyzed by DNA ligase (Ligase) results in the serial transfer of AMP (adenosine 5-monophosphate) to an active site lysine (step 1) and then to the 5-PO 4 end of DNA (step 2). The ligase chain reaction (LCR) is an amplification process that differs from PCR in that it involves a thermostable ligase to join two probes or other molecules together which can then be amplified by standard polymerase chain reaction (PCR) cycling (Barany, 1991).

The ligase chain reaction (LCR) following PCR is one of the most sensitive and specific methods for detecting mutations, especially single nucleotide polymorphisms (SNPs). Ligase chain reaction (LCR)--overview and applications PCR Methods Appl. Polymerase chain reaction (PCR) (see Chapter 6) ushered in these technologies and was soon accompanied by numerous newly developed amplification techniques, including ligase chain reaction (LCR). LCR involves the use of two pairs of probes, each pair being complementary to a strand of the denatured target DNA. The participation of human DNA ligases in nuclear right panel and mitochondrial left panel DNA replication and repair is indicated with the major enzyme are bolded. Apart from the thermostable polymerase as needed in conventional PCR, LCR also requires another completely different enzyme, ligase, to . In general, a ligase catalyzes the following reaction: Nucleic acid sequencing methods and related products and methods for detection and presentation of the same are disclosed. Ligase chain reaction (LCR), employing just oligonucleotide probes and Principle and DNA ligase, is capable of detecting approximately <_ 1000 copies of a specific applications target DNA sequence in the presence of a vast excess of other DNA sequence information. The chain reaction is repeated in three steps in the presence of excess probe: (1) heat denaturation of double-stranded DNA, (2) annealing of probes to target DNA, and (3) joining of the probes by thermostable DNA ligase. 1994 Feb;3(4):S51-64.
