5, frozen vacuum drying method

(1) Preparation of lyophilized tube: Neutral hard glass, drying, sterilization.

(2) strain culture: bacterial spores shed; release, mold spore fullness.

(3) preparation of protective agent: preparation, sterilization, inspection.

(4) Preparation of bacterial suspension: 2-3ml protectant.

(5) dispensing samples: bacterial suspension 0.2ml per tube.

(6) Pre-freezing: Program temperature control instrument cooling.

(7) Freeze-vacuum drying: evacuated at -50 ° C.

(8) Remove the sample: tapping the loose target.

(9) The second drying.

(10) Melt seal.

(11) Survival test: take a tube for viability check.

(12) Save: 4 ℃ save.

Polymerase chain reaction (PCR) is a new technology that simulates the process of natural DNA replication and amplifies specific DNA (or RNA) fragments in vitro. In this experiment, the double stranded DNA to be tested was denatured into a single strand at 94 ° C as a template, and then a pair of synthetic oligonucleotide primers were added. The primers were respectively complementary to the two ends of the DNA fragment to be amplified, Low temperature annealing, primer and template complementary combination. Under the condition of 72 ℃, the primers binding to the template under the DNA polymerase catalyzed the use of four kinds of dNTPs in the reaction system as raw materials, and extended and synthesized two new DNA strands according to the base complementary pairing manner. After 20-30 cycles, specific target DNA can be amplified millions of times more. PCR products after agarose gel electrophoresis can be observed after the specific amplification bands.
