Description
Technical Field
The invention belongs to the technical field of PCR, and particularly relates to a PCR8 row pipe with high practicability.
Background
Polymerase Chain Reaction (PCR) is a molecular biological technique for amplifying specific DNA fragments, which can be regarded as specific DNA replication in vitro, and the greatest feature of PCR is the ability to greatly increase minute amounts of DNA. Therefore, whether it is ancient organisms in fossils, remains of historic people, or hair, skin or blood left by the murder in decades ago, PCR can be amplified and compared as long as DNA at a single spot can be isolated. This is also the power of "trace evidence". The idea was first proposed by Mullis in the united states in 1983, from which the polymerase chain reaction, i.e., the simple DNA amplification method, was invented in 1985, implying the real birth of PCR technology. By now 2013, PCR has evolved to third generation technology. In 1976, chinese scientist Qian Jiayun discovered stable taq dna polymerase, also made a fundamental contribution to the development of PCR technology. PCR is to use the fact that DNA becomes single-stranded at a high temperature of 95 ℃ in vitro, and primer and single-stranded are combined according to the base complementary pairing principle at a low temperature (usually about 60 ℃), then the temperature is regulated to the optimal reaction temperature (about 72 ℃) of DNA polymerase, and the DNA polymerase synthesizes complementary strand along the direction from phosphoric acid to pentose (5 '-3'). The PCR instrument based on polymerase is actually a temperature control device, and can well control the denaturation temperature, renaturation temperature and extension temperature
When the PCR is placed in the eight-joint pipe, the eight-joint pipe needs to be placed on the bent, and the eight-joint pipe is easy to separate from the bent due to the light weight, so that loss is caused.
