Abstract

The invention discloses lysate and kit for carrying out a PCR on a blood and oral cavity swab, and belongs to the technical field of molecular diagnosis. The kit comprises the lysate. The lysate is prepared from 60-70 mM of Tris-Hcl, 16-17 mM of ammonium sulfate, 6-7 mM of Mgcl2 6H2O, 6-7 micron M of EDTA, 1.5-2.5 micron M of SDS and 30-55 micrograms/ml of protease K, wherein the pH value of Tris-Hcl is 8.2-9. The blood and oral cavity swab treated with the lysate can be directly subjected to the PCR, and an existing detection technology is greatly optimized.

Description

technical field [0001] The invention belongs to the technical field of molecular diagnosis, and in particular relates to a lysate and a kit for performing PCR on blood and buccal swabs. Background technique [0002] PCR, or Polymerase Chain Reaction (Polymerase Chain Reaction), is an enzymatic synthesis reaction technology that relies on DNA polymerase in the presence of template DNA, primers and four deoxyribonucleotides. This technology has been widely used in the fields of microbiology, genetics and forensics since it was invented in 1958 by Kary Mullis and colleagues in the human genetics laboratory of Cetus Corporation in the United States. [0003] Real-time fluorescent quantitative PCR technology (qPCR) was introduced by Applied Biosystems in 1996. This technology refers to adding fluorescent groups or fluorescent dyes to the PCR reaction system, using the accumulation of fluorescent signals to monitor the entire PCR process in real time, and finally drawing a standar...
