Protocols

  1. PCR - Veena
    • First, you might want to dilute some of your miniprep product (that is, your plasmid DNA...this is your template) to a concentration of 1ng/μL, and label this tube; for example, if I have BSMT plasmid DNA that I got from a miniprep and it's at a concentration of 50ng/μL, I'd label a new tube "BSMT for PCR" and add to that tube 49μL of water and 1μL of the 50ng/μL plasmid DNA.
    • You should also prepare 25μM tubes of primer, if you don't have them already.
    • In each tube, you want a total reaction volume of 50μL, with 1ng of your template DNA, .6μL of each primer (forward and reverse) (.6 μL of the 25μM primer yields roughly 300 nM final concentration of that primer, which is the goal), and 49 μL of Tom's PCR mix.
    • Run the tubes on the thermocycler at: 95deg for 3:00, then cycle through: (a) 94deg for :30 (b) 55deg for :30 (c)68deg for 2:15, then 72deg for 10:00
  1. Digestion - Kate [[../Notebook/2006-6-27#Restriction Digest |6-27-2006]]
  2. Ligation - Veena [[../Notebook/2006-6-21#Ligation reaction |6-21-2006]] Knight
  3. Transformation - André Transform competent cells
  4. Sequencing - Bo
    • Reconstitute primer of X nMoles by adding 10*X uL of water, making 100 uM solution (can turn into 25 uM by using 40*X)
    • Centrifuge for 15 seconds.
    • Add 180ng of template DNA
    • Add 3.2 pMoles of primer (0.128 uL from 25 uM working solution)

  6. Autoclaving (waste, media, etc.) - Stephen
  7. Pouring/running gels - Veena
  8. Glycerol stocks - Stephen
