3, the quality evaluation of target DNA enrichment probe
In triplicate, repeating test every time, specific step is as follows for experiment:
1) test experiments scheme: the full-length genome library sample of 10 people of selection, each sample are divided into two groups, two components Confirmatory experiment is not carried out by different batches.
The target DNA in above-mentioned 10 samples is captured using target DNA enrichment probe:
Target DNA enrichment probe is mixed with DNA full-length genome library, the chondriogen in sample is just hybridised to probe On, absorption is combined by biotin and Streptavidin MagneSphere, removes the DNA fragmentation of nontarget area through elution processing, from And it is enriched with human mitochondrial full genome, the measurement of 2X150bp high pass is carried out using new-generation sequencing instrument Illumina Nexseq500 Sequence.Specific step is as follows:
A1 it) prepares following mixed system: taking 500ng DNA full-length genome library (20 μ l, 25ng/ μ l), 10 μ l Buffer BL, the target DNA that 5 μ l steps 2 obtain are enriched with probe solution, 6 μ l Blocking Oligo Mix;
It a2) will be in the mixed system PCR instrument of step a1): 95 DEG C, 7min, 65 DEG C later, 2min;
A3 the 23 μ l of Buffer HY of 65 DEG C of preheatings) is taken to be added to step a2) it reacts in the system terminated, then in PCR Hybridize 22 hours for 65 DEG C on instrument.
A4 MyOne beads (Invitrogen)) is taken out, whirlpool concussion makes magnetic bead sufficiently suspend, and of short duration centrifugation makes pipe lid On beads be centrifuged to bottom of the tube.
A5 in the centrifuge tube for) taking 50 μ l MyOne beads to new 1.5ml, whirlpool shakes at least 5s, keeps magnetic bead abundant It suspends, is put into after of short duration centrifugation on magnetic frame one minute.
A6) centrifuge tube remain stationary (should not rotating centrifugal pipe) on magnetic frame, and careful inhale abandons supernatant.
A7 centrifuge tube) is removed, the 1X Binding Buffer (binding buffer) of 50 μ l is added, the concussion of rotation nest is at least 5s is put on magnetic frame static one minute after of short duration centrifugation, and careful inhale abandons supernatant.
A8 step a6) is repeated) and a7) twice (altogether three times).
A9 centrifuge tube) is removed, 100 μ l 2XBinding Buffer (binding buffer) are added, the concussion of rotation nest is at least 5s is transferred to completely in a new centrifuge tube after of short duration centrifugation.
A10) be transferred to the product of step a3) completely in the centrifuge tube of beads (about 200 μ l of total volume, while handling multiple Several lower mixings are flicked when sample, after mixing), it is small to be placed in room temperature rotation 1 on Rotator by rotation nest concussion at least 5s (not having to centrifugation) When.
A11) after above-mentioned steps, primary using WB1buffer room temperature cleaning beads, then 15minutes exists It is washed in WB3buffer 3 times, 65 DEG C, 15minutes/ times.
A12) DNA bound is eluted using Buffer Elute.The DNA of elution finally expands 15 circulations, utilizes following journey Sequence: 98 DEG C, 30s (1cycle);98 DEG C, 25s, 65 DEG C, 30s, 72 DEG C, 30s (15cycles);72 DEG C, 5min (1cycle) is right The DNA of elution carries out PCR amplification.
