Description
Technical field
It is an object of the present invention to provide a kind of for swine fever virus, porcine reproductive and respiratory syndrome virus and swine influenza virus H1
The triple fluorescent RT-PCR detection kit of hypotype and primer, probe.
Background technology
Swine fever virus (Classical swine fever virus, CSFV) is ssRNA virus, flaviviridae Pestivirus
Belonging to, virion is rounded, and its RNA is single-stranded positive.Porcine reproductive and respiratory syndrome virus (Porcine reproductive
And respiratory syndrome virus, PRRSV) it is Arterivirus, virion is ball-type, is that one has capsule
The single strand plus RNA virus of film.Swine influenza virus (Swine influenza virus, SIV) H1 hypotype is orthomyxovirus section first
Type influenza virus, virion pleomorphism, there is cyst membrane, genome is segmented sub-thread strand RNA.Three of the above cause of disease is
RNA viruses, all can cause pig industry tremendous economic to lose, and the clinical symptoms caused has similar part, it could even be possible to mix simultaneously
Close and infect, but hazardness, popularity and prevention and control measure thereof that Different Kinds of Pathogens infection causes are completely different.Therefore, a kind of district is set up
The detection method dividing three kinds of cause of diseases is extremely important, and the sensitiveest detection method can effectively prevent transmission of disease, reduces economy
Loss.
The immunologys such as ELISA, RT-PCR and molecular biology for detection have been applied in the diagnosis of above-mentioned epidemic disease, but
Being currently used primarily in the detection of single cause of disease, the aspect such as its susceptiveness, specificity and simplicity all needs to be improved further, commonly
The judgement of RT-PCR testing result needs product is carried out gel electrophoresis analysis, complex operation.The present invention uses triple fluorescent RT-
PCR detection method can detect differentiation these three virus simultaneously, not only can improve susceptiveness, specificity and simplicity etc., also may be used
Save plenty of time and cost.
Above-mentioned 3 kinds of cause of diseases can be by conservative region design specific primer and probe, carrying out fluorescence RT-PCR inspection
Survey.Fluorescence real-time quantitative PCR (Real-time PCR) is the probe adding fluorophor labelling in PCR reaction system, utilizes
Whole PCR process is monitored in fluorescence signal accumulation in real time, is analyzed result finally by amplification curve.AllgloTMProbe is
The latest generation fluorescent quantitation probe that AlleLogic Biosciences company of the U.S. releases, it breaks traditions Taqman probe
Reporter group one end, one end essence go out the restriction of group, its sharpest edges are the fluorophors that probe two ends labelling is same, probe
The mutual cancellation of fluorophor before hydrolysis, is report luminophore after hydrolysis, be greatly improved fluorescence intensity and the spirit of probe
Quick property, AllgloTMContaining the special chemical group (BGB) that can improve Tm value above probe dye, probe can be greatly improved
Specificity.Multiple fluorescence quantitative PCR technology refers to expand multiple purpose base in same fluorescent quantitative PCR is tested simultaneously
Cause.At multiple quantitative application, AllgloTMThe problem that the TaqMan probe that avoids probe mutually suppresses, probe dye uses
It is easier the chemical group of enzyme action, a plurality of AllgloTMProbe interferes the least in a reaction system, make one glimmering
The effect of photoreaction detection multiple pathogenic microorganisms is the best.According to this principle design specificity multi-fluorescence probe, conventional
Fluorophor has MAR, JUP, URA etc., can detect multiple fluorescence signal by different fluorescence detection channel simultaneously.Due to this
Method introduces specificity amplification primer and fluorescent probe so that sensitivity and the specificity of detection are increased significantly
By force, thus avoid that other detection method specificitys are the highest and the problem of easy missing inspection.
