Golden Gate Assembly of BD002 to Replace HsvtkTATA with CMV and HPK Promoters (Third Try)

  • Dilute the purified PCR product to 20 fmol/μL
    • Measure ng/μL of the purified sample.
    • The volume of purified DNA (x) you will need to dilute in a final volume of 20 μL = length in bp ÷ measured ng/μL * 20 fmols/μL * 650 fg/fmol ÷ 1,000,000 fg/ng * 20 μL final volume
    • Formula: x = length in bp ÷ measured ng/μL * 0.013 * 20

Backbone vector [math]\displaystyle{ X= (4600 / 209 ) * 0.013 * 20 = 5.72 }[/math]

HPK [math]\displaystyle{ X= (516 / 70 ) * 0.013 * 20 = 1.91 }[/math], [math]\displaystyle{ 1.91 + 18.1 = 20 }[/math]

CMV [math]\displaystyle{ X= (588 / 42 ) * 0.013 * 20 = 3.64 }[/math], [math]\displaystyle{ 3.64 + 16.36 = 20 }[/math]

  • Bacterial transformation , Fast transformation protocol
    • Add total volume (10.0 μL) to 30 μL DH5α, Incubate on ice for 20 min.. Plate cells on pre-warmed LB agar + AMP antibiotic. Grow overnight at 37°C.


No colony on plates for BD003. and 8 of colonies on BD004, and BD004 plasmids transformed in DH5α.
