    2. Material dosage/μl
    PCR product(after purification) 17
    restriction enzyme buffer 3 (/4)
    restriction enzyme 1(0.5 each)
    ddH20 4
    Total 25

    PCR product cutting sites restriction enzyme Buffer
    pHhl1-hhl1 BsaⅠ+EcorⅠ 3μlPstⅠ+1μlBsaⅠ
    hhl1 PstⅠ+EcorⅠ 3μlPstⅠ

    phyB BsaⅠ+PstⅠ 3μlPstⅠ
    pif1 BsaⅠ+PstⅠ 3μlPstⅠ

  2. Place the tube in a 37℃ incubator, stand for 1 hour.

  3. Water bath the tube in 65℃ for 20 mins to end the digestion reaction.

4.chemical conversion

(1)Preparation of LB Broth

  • 2g peptone

  • 1g NaCL

  • 0.2g glucose

  • 1g yeast

  • Add water to 200ml, regulate the pH at a range of 6.8~7.2

Add water to 200ml, regulate the pH at a range of 6.8~7.2

(2)Preparation of LB Broth Medium

(3)Preparation of chloromycetin solution

  • 10ml ddH20

  • 0.25g Chloromycetin

Add trace amount of NaOH until the chloromycetin dissolves completely

(4)Add chloromycetin solution into LB broth, mix them

(5)Add competence DH5α （100μl）into 10 μl plasmid，mix them gently, and ice bath

(6)Heat the solution in 42℃ water bath，and ice-bath 2min (Be sure not to shake the centrifuge tube)

(7)Add 890μl, 37℃ preheating LB broth, mix them gently ,shake them in the condition 37℃, 150rpm for 45min.

(8)4000rpm centrifuge 5min, discard 900 μl supernatant ,suspend the 100μl sediment gentlely

(9)Spread the solution on the LB broth medium evenly, after it is dried, culture it upside down in the 37 ℃ incubator for 16 hours
