Jess enjoying pipetting buffer into her restriction mixture.

We have conducted restrictions in varying concentrations and total volumes; however they all follow the same basic procedure. Below are two of the different restrictions we carried out.


  • 46μl MillQ H2O
  • 10μl 10 x buffer
  • 40μl plasmid sample
  • 2μl enzyme 1
  • 2μl enzyme 2

Total volume = 100μl

Concentrated

  • 10μl MilliQ H2O
  • 3μl 10 X buffer
  • 10μl plasmid sample
  • 1μl enzyme 1
  • 1μl enzyme 2

Total volume = 30μl

The DNA purification kit we use to purify enzymatic reaction mixtures.

  • Incubate solutions for 90 minutes in a 37°C water bath.
  • If DNA is to be run on a gel and a band cut out, this can be done without purifying the DNA. For all other downstream applications or for storage, solution must be purified to remove the enzymes.
