Didn't have enough of the backbone so started another PCR. 1-4 are int receiver vector P112 P123, 5-6 are purified PCR product of receiver backbone P112 P123.

Ran PCR products from yesterday on a gel. 5ul of reactions 2-9, all 30 of 1 so I can gel extract because there should be two bands and I only want one.
DpnI digest PCR reactions 2-7 and 9 with positive and negative controls (didn't run reaction 8 because I checked the gel early and saw that there was no DNA there).
Controls Positive control was a miniprepped plasmid at 100ng/ul concentration.

Incubated at 37°C for 55 minutes, sat on the bench for 3 minutes, heat inactivated at 80 for 5 minutes.
Cleaned using zymo DNA clean and concentration-5 kit (columns from gel extraction kit). Added 150ul of DNA binding buffer to DpnI reactions.
Gel extracted PCR reaction 1. Saw a smaller band above, think I got the correct band.

Didn't have enough of the backbone so started another PCR. 1-4 are int receiver vector P112 P123, 5-6 are purified PCR product of receiver backbone P112 P123.
