Week 6:Electro-transformation and screening of the genomic library
Wednesday • Look at transformation results • Transform the following: • Water • pUWL500 • Library (L1 –L4) • Thursday • Screen colonies • Ex 9A and 10 pt I and II due with the following questions: • Ex #9 1,3,4,5 Ex#10 all
Wednesday • Transformation of ligation: • We will transform the following, each in 35 uL of competent cells: • 1 uL water • 20ng pUWL500 • 5 uL of the ligation reactions • Remember to dialyze everything before transformation, and plate on LB + Amp!!!
Transformation tips: • Keep cells on ice at all times • Only add cells to cold cuvettes • Immediately add 1 mL SOC media immediately after electroporation • Incubate 30 minutes after adding SOC
Checklist: • Plate the following volumes from the transformations: • Negative control: 100 uL • pUWL500: 100 uL • Ligation reactions: 200 uL for each reaction • Save the ligation transformations for next time • Place plates in 37° incubator
Week 6:Electro-transformation and screening of the genomic library
Last time: • We transformed controls and our ligation reactions. Today we will observe the results.
