To insert oligos into pSB1A2 with insert BBa_J100028
1 µL assembled oligos cooled overnight
1 µL (10 ng) pSB1A2+J100028
5 µL dH2O
1 µL 10X Promega Ligase Buffer
1 µL 500 mM NaCl
0.5 µL Bsa I restriction enzyme
0.5 µL T4 DNA Ligase
10 µL final volume (be sure to perform a negative control ligation)

Turn on the PCR machine.
Program it for the following cylces:
40 cycles of 37C for 1 minutes/16C for 1 minutes
80C for 15 minutes
22C holding temperature
This DNA ligation is ready for transformation.

Transformations Use all 10 µL of the ligations for a transformation.
You will want to do a negative control where you leave out the assembled oligos and add one more microliter of water.
You will also want to perform a positive control of K315008 which contains pLacI+RBS+RFP in plasmid pSB1A2.

Take one tube of 100 µL competent cells and use 30 µL of cells for each of the three transformations listed above. Plate all three transformations on LB amp plates.


This protocols was developed at MWSU by Dr. Todd Eckdahl, and modified at Davidson College by students in Biology 111 and Romina Clemente.
