Description
Technical field
This utility model belongs to the technical field of biological engineering experimental instrument and equipment, relates to belonging to the amplification of PCR reagent, glimmering
Photo measure detection technique, more specifically, this utility model relates to the data of ribonucleic acid chain type polymerization amplified reaction and processes one
The detection device of body.
Background technology
Round pcr (DNA Polymerase Chain Reaction:DNA polymerase chain reaction) is the mid-80
The isothermal DNA amplification grown up, is that Khorana proposed this imagination in 1971 the earliest.American scientist Kary
Mullis etc. achieved this imagination in 1985, had invented the round pcr being with historically new significance.Apply this technology can be
In one test tube, genes of interest to be studied was expanded within a few hours 100,000 or even million times, it is simple to naked eyes can directly be seen
Examine and judge.Due to this isothermal DNA amplification have special, sensitive, productivity is high, quick, easy, reproducible, easily from
The outstanding advantages such as dynamicization, have therefore obtained the generally accreditation of life sciences circle, and the most therefore Kary Mullis obtains 1993 years
Nobel chemistry Prize.
PCR is one of the most frequently used molecular biology method.Removing in the field of basic scientific research, PCR examines at clinical medicine
Disconnected, life sciences, engineering in medicine, genetics, agricultural seed selection educate clock research and development, and criminal calibrating screen in be all essential
, also it is the most authoritative reliable technology.
Archaeal dna polymerase chain reaction (PCR): be the technology being carried out DNA amplification by thermal cycle reaction.Thermal cycle refers to solid
The circulation of variations in temperature in fixed time interval.Using heat-staple archaeal dna polymerase, PCR can be de-with the synthesis material of DNA
Oxygen ribonucleoside triphosphote synthesizes substantial amounts of DNA copy.PCR reaction includes three steps: degeneration, anneals and extends.Degeneration is PCR cycle
The first step, the hydrogen bond between DNA base is opened and is melted DNA double chain and produce single stranded DNA by it.Annealing then reduces the temperature to
Of a sufficiently low, enable oligonucleotide primer to be attached on DNA profiling.During extending, archaeal dna polymerase is by new for synthesis double
Chain DNA.After repeatedly thermal cycle (each cyclic amplification one times), the DNA of trace will be expanded to the concentration of instrument detection.
Common PCR detection technique has two kinds:
After the first is multi cycle polyreaction, end-product (end-point analysis) is detected by DNA running gel
Quantitatively.Shortcoming is because being limited by electrophoretic techniques sensitivity, and this method is simply " sxemiquantitative ".
Second method is: utilizes fluorescently-labeled probe (fluorescent probes), monitors polyreaction in real time
Change of production in each circulation.The quantity of initial template to be expanded can be calculated by cycle threshold (Ct) value and draw.
Ct value is exactly the period when fluorescent value is apparently higher than background background.
The real-time PCR reagent sold in the market is mainly based upon the TaqMan of fluorescent probe and based on SYBR
Green dyestuff is fitted together to the two kinds of technology surveying DNA double chain total amount.The limitation of the method is: 1, need external source standard sample or
Person's endogenous gene carrys out standardization to paint calibration directrix curve.2, the amplification that non-specific responding causes will affect the credibility of Ct value.
Research worker finds that following three factors and polyreaction success or not have a dependency: 1, the limiting dilution of sample；
2, end-product total amount；3, product amount is distributed (Poisson distribution) relation with the handkerchief pine of initial DNA concentration.
The concentration of specimens of initial DNA just can be extrapolated by regulating and controlling and measuring the above-mentioned factor.
