DNA Ligation

DNA ligases are used with restriction enzymes to insert genes into plasmids.


Materials

  • DNA plasmids double digested previously(eg.XbaI and PstI); . Measure concentration in Nanodrop beforehand.
  • Biobricks double digested previously(eg.SpeI and PstI )
  • equal amount of T4 ligase.


Procedure

The following volumes apply to a 20µl DNA ligation.

add the following components to PCR tube:

  • 9µl DNA plasmids
  • 1µl biobricks
  • 10ul T4 ligase
  • MIX the reaction by stiring
  • Incubate the reaction at 16*C for 2hrs or overnight to ensure complete ligation.
