Introduction
Professional interpretation of fluorescent PCR detection method for honey bee sac brood disease
Background of standard formulation and analysis of technical evolution
This standard was proposed by the Ministry of Agriculture of the People's Republic of China and is under the jurisdiction of the National Technical Committee for Animal Health Standardization. Its drafting units include Jilin Entry-Exit Inspection and Quarantine Bureau, Jilin University and Fujian Entry-Exit Inspection and Quarantine Bureau.
The technical basis of the standard is mainly based on fluorescent quantitative PCR (qPCR) detection technology, which is an important progress in the field of molecular biology in recent years and can achieve rapid and highly sensitive pathogen detection.
| Standard Framework | Technical Requirements | Scope of Application |
|---|---|---|
| Reagents and Materials | The preparation methods of various reagents are clearly specified, including the requirements for key components such as primers and probes. | Applicable to the detection of cystic brood disease in bees and their larvae. |
| Instruments and Equipment | Requires the use of professional equipment such as fluorescent quantitative PCR amplification instrument and high-speed centrifuge. | Emphasis on the importance of laboratory environment and operating specifications. |
Reagent Preparation Instructions
The preparation method of phosphate buffer required by the standard is shown in Appendix A, including the preparation of sodium dihydrogen phosphate and disodium hydrogen phosphate solutions and high-pressure sterilization. The preparation of diethyl pyrocarbonate treated water requires standing and high-temperature sterilization.
The specific preparation method of RNA extraction reagent and preservation solution is: add chloroform to the total RNA extraction reagent lysis solution, mix well, centrifuge and take the supernatant for use.
Overview of the detection process
- Sample collection and processing:According to the requirements of GB/T18088, collect 20 to 30 suspected infected honey bee larvae.
- RNA extraction:Use total RNA extraction reagent for lysis, and take the supernatant after centrifugation for subsequent testing.
- cDNA synthesis:Completed on an ice box, using random primers and reverse transcriptase to catalyze the generation of cDNA.
- PCR amplification and analysis:Prepare the PCR reaction mixture, add the fluorescent probe and perform quantitative PCR amplification, and set appropriate cycling conditions to detect the amplification amount of the target virus.
