6)Repeat step(5)Once, it is inverted a moment;
7)After tube wall dries, the μ l dissolving DNAs of TE buffer solutions 40 are added, being blown and beaten with suction pipe makes DNA fully dissolve.
(2)DNA concentration is determined and purified
The μ l of sample 20, plus ultra-pure water are taken to 600 μ l, is fully mixed, determining wavelength with ultraviolet specrophotometer is respectively 260
OD values when nm, 280 nm, 320 nm, calculate the concentration and purity of DNA.
DNA concentration (μ g/ml)=(OD260-OD320) × 50 μ g/ml × extension rate (30)
DNA purity=(OD260-OD320)/(OD280-OD320)
DNA purity represents that purity is good when being 1.8;<Represent that protein content is too high when 1.6, purified using chloroform/isoamyl alcohol extraction;>
Indicate that RNA pollutes when 1.9, can be processed with RNase.
(3)PCR reacts
1)Design of primers
Design ITPA 94C>The pcr amplification primer thing of T, as shown in table 1.All primer sequences verify that it is closed through NCBI Blast
Rationality and specificity.
The primer sequence of table 1
2)PCR reaction systems
PCR reaction systems are 25 μ l, including 3 μ l, 10 × Taq buffer of DNA profiling 2.5,2 μ l of μ l, dNTPs
(0.25mmol/L), each 1 μ l of upstream and downstream primer (10 μm of ol/L), the μ l of ExTaq 0.15 (5U/ μ l), uses ddH2O supplements are total
Volume is to 25 μ l.
3)PCR reaction conditions are as shown in table 2
The PCR reaction conditions of table 2
4th, the detection of PCR primer:Agarose gel electrophoresis
Glue:Appropriate agarose is weighed, adds 0.5 × TBE solution to be configured to 1% suspension, be heated in micro-wave oven completely
Dissolving, adds the Goldview of final concentration of 0.05 μ l/ml, in the abundant rubber moulding for mixing placing flat of falling back, gel thicknesses
About 5 mm, plug comb, static 20 ~ 30 min.
Loading:The gel that will be made is put into electrophoresis tank, electrophoretic buffer(With 0.5 × TBE of batch)Liquid level is higher by gel table
The mm of face 1 ~ 2, takes after 5 μ l amplified productions mix with 1 μ 6 × Loading of l buffer, in sequentially adding well;190 V
The min of electrophoresis 15.
5th, result
Electrophoresis result is observed under uviol lamp, and in automated imaging on gel imaging system, as a result as shown in Figure 1, using this hair
Bright primer pair ITPAwtF/ITPAwtR and ITPAmtF/ITPAmtR and PCR method, can be with Testing and appraisal ITPA 94C>T bases
Because of the genotype of pleomorphism site.
From the point of view of clinical observation, no mutant homozygote is to the adverse reaction rate of purinethol class medicine apparently higher than mutation
Heterozygote, and no mutant homozygote and the rate of adverse reactions both heterozygous mutation are better than wild type.
Therefore, it can using primer pair ITPAwtF/ITPAwtR and ITPAmtF/ITPAmtR of the invention and PCR method
Detection ITPA 94C>The genotype of T gene polymorphism sites, so as to judge detection object to the bad anti-of purinethol class medicine
Situation is answered, and then instructs personalized medicine.The invention provides a kind of simple and easy to apply and with the PCR of very strong clinical value
Method and primer.
