I. Check Old Plates for Growth

  • RESULTS: There was XL1-Blue colony growth on Kan50 plates from 15 Aug 2012 that was not present on controls for the 1:1 (~4 colonies) and 1:2 (~1 colony) vector-cassette ligations.

II. Colony PCR

  • Mix Reagents:
  • Mix according to the following table
1 Reaction Master Mix (x6)
Reagent (uL) (uL)
water 17.25 103.5
5x KAPA HiFi buffer 5 30
10 mM dNTP mix 0.75 4.5
10 uM primer (F) 0.75 (pBf) 4.5 (pBf)
10 uM primer (R) 0.75 (pBr) 4.5 (pBr)
Template - -
KAPA HiFi polymerase 0.5 3
  • Aliquot 50 uL of mix to 6 PCR tubes
  • Note: Last tube (control) had less than others
  • For templates, use a pipette tip to touch a colony from one of the plates, dip it into a PCR tube, and then drop it into a culture tube as described in the next section (III). Do not use template for control.
  • Run PCR
Step Temp (oC) Time
1 95 5 m
2 98 20 s
3 63 15 s
4 72 5 m
5 GOTO 2 34x
6 72 5 m
7 4


III. Start Liquid Cultures for PCR Colonies

  • Make LB-Kanamycin (50 ug/mL) media
  • 10 mL of LB media
  • 10 uL of Kanamycin stock (50 mg/mL)
  • Aliquot ~2 mL of LB-Kanamycin media to 5 culture tubes
  • Drop the pipette tip from each colony PCR into a tube labeled in the same way as the PCR tubes
  • Incubate overnight with shaking at ~32 oC
