<p id="coop">Oligonucleotides synthesized in powder form need to be centrifuged for 1 min at 10000rpm to assemble powders to the bottom of the EP tube.And be careful to open the cap. </p>

<p >合成的寡核苷酸呈粉末状，使用前需要10000rpm离心1min，使寡核苷酸干粉集中在管底，使用时小心开启瓶盖。 </p>

<p id="coop">Make sure that the synthesis report is consistent to the OD number on the primer label,and check the number of the dispensing tube before the dissolution of oligonucleotides.The volume of water added to make 10umol/L oligonucleotides’ solution is calculated according to the synthetic single report of each primer. Add sterile deionized water and keep it at room temperature for 2min.And reverse the tube to accelerate the progress of solubilization. Finally, collect substances at the bottom of the tube after centrifugation.</p>

<p >溶解寡核苷酸前核对合成报告单与引物标签上的OD数是否一致，并核对分装管数。根据每个引物的合成报告单计算出配制10umol/L浓度的寡核苷酸需要加入水的体积，加入去离子无菌水，室温放置2min，反复振荡助溶，再离心将溶液收集到管底。 </p>

<p  id="coop">Select the white colony on culture and culture it. Then we extract the plasmid and use it as template in PCR to identify the colony. In theory, the reconstructed vector with mlrA fragment is 1293bp and the empty vector without mlrA fragment is 314bp. So, the result shows that the white colony we select has reconstructed vector with mlrA fragment in it.</p>

-
<p >(2)&nbsp;无菌条件下，将30mL菌液转移至离心管中，冰上放置10&nbsp;min，使培养物冷却至0&#8451;。 </p>
 
-

-
<p >热激转化过程： </p>
 
-
<p >(1)&nbsp;取新鲜制备或者从-80&#8451;冰箱中取出感受态细胞JM109悬液，冰浴解冻。 </p>
 
-
<p >(2)&nbsp;加入构建好的重组克隆载体质粒pSB1C3-A(含量不超过50ng,体积不超过10&#956;l)，轻轻摇匀，冰上放置30分钟后。 </p>
 
-
<p >(3)&nbsp;将该EP管放入预加温至42&#8451;的水浴中，放置90s，快速转移到冰浴中，使细胞冷却1-2&nbsp;min。 </p>

5、Sequence Split

The maximum allowable assembly oligo length is equal to the target assembly oligo length (60). This may cause some weird behavior, especially in terms of overlap melting temperature.

2、Mixing of primers

Oligonucleotides synthesized in powder form need to be centrifuged for 1 min at 10000rpm to assemble powders to the bottom of the EP tube.And be careful to open the cap.

Make sure that the synthesis report is consistent to the OD number on the primer label,and check the number of the dispensing tube before the dissolution of oligonucleotides.The volume of water added to make 10umol/L oligonucleotides’ solution is calculated according to the synthetic single report of each primer. Add sterile deionized water and keep it at room temperature for 2min.And reverse the tube to accelerate the progress of solubilization. Finally, collect substances at the bottom of the tube after centrifugation.

Every six primers are combined to one group.Add 4ulbeginning fiprimer, 1ulintermediate primer and 4ul end primerto a new EP tube, then add sterile deionized water to 20ul, mix them up as spare.

(2) Wait until the solution in culture is full absorbed by cell, then invert the plate and culture it in 37℃ overnight.
Sequence test
Replace the fragment(45bp) between EcoR I site and Pst I site with mlrA(1024bp) on pSB1C3 vector and then we get the reconstructed plasmid, pSB1C3-A.

 

Fig3.Reconstructed vector pSB1C3-A

Select the white colony on culture and culture it. Then we extract the plasmid and use it as template in PCR to identify the colony. In theory, the reconstructed vector with mlrA fragment is 1293bp and the empty vector without mlrA fragment is 314bp. So, the result shows that the white colony we select has reconstructed vector with mlrA fragment in it.

                   Fig 4. The identification of reconstructed vector pSB1C3-A

Results:

1.L1 and L2 is 1300bp and it confirms that the reconstructed vector has mlrA on it.

2.M is the 100bp Ladde Marker.

Sequencing result shows that the sequence of synthetic mlrA gene is exactly same as sequence of designed sequence.
