Today in the lab
Dan
- Gel of sample 2T
- For some odd reason all of the DNA stayed in the well... Could be some sort of salt contamination from NEB buffer 1, or a very large autoligation product. I will test the former by doing PCR cleanup and switching to ligation buffer and then run the gel again.
- Digestion of 1A 0B and both S and D
- The above DNA fragments were digested with PstI and SphI in Neb buffer 1, enzymes were denatured after an hour
- PCR cleanup was performed on the digested products, eluted with 50 uL water.
- Ligation
- Ligation of the DNA obtained from PCR cleanup was run overnight at 16 C
Matt
- Miniprep
- I performed a miniprep of the inoculated PTP2 plasmids and yielded good concentrations for all samples.
- I then proceeded to digest each sample with NcoI and run them on a gel for confirmation.
- It appeared as though NcoI only cleaved at one site on the plasmid - linearizing the plasmid. I am going to try to attempt another digestion with EcoRV/EagI which should give two definitive bands - if successful then I will PCR amplify with SLN1 primers for integration into yeast.
