PCR Screening for Targeted ES Colonies in 96 Well Plates

  • Use multiple channel pipet to pool DNA samples from each column, 10 l from each well. (one mixed sample contains DNA from eight wells). Mix thoroughly.
  • Perform nested PCR.

Use the same nested PCR to screen individual well in the row that the pooled sample shows positive.

We use Platinum Taq (Invitrogen catalog number 10966) for PCR product < 3.5 kb. For PCR product longer than 3.5 kb, we use Elongase (Invitrogen catalog number 10480-010).
