7/07/2014 - Garrett Jensen.
- Today I looked around for the M17 media that supposedly was delivered 2 weeks ago. Brother Lee and Dr. Robison both said that it was not in their lab but they are the only ones who signed out a package from Fischer Scientific 2 weeks ago.

July 7th Michael Linzey
Redo PCR
- I realized that I was using the wrong primers for the PCR to check in my spacer was in the region I was trying to do
- I got the primers that I ordered on the 30th
- I set up the PCR
o I used a Taq polymerase because our red Taq is not working really well
- Let the reaction go over night
- I also prepared a gel for gel electrophoresis

7/09/2014 - Garrett Jensen.
- Today I ran a PCR on the DNA that Skip isolated from S. thermophilus on June 26 using the universal 16S ribosomal primers. I used taq polymerase instead of Redtaq because the redtaq has been having some issues lately. If there is microbial DNA present then we may be able to get PCR for the CRISPR to work from it. In the meantime I am waiting for our M17 media to show up.

July 9th Michael Linzey
Came in to check to see if it worked
- I ran the 8 PCR products in the gel that I had prepared
- Used a blacklight to see if I got anything
o There was definitely PCR product
o Talked to Dr. Grose and she said that it looked good
- Prepared an overnight for the two darkest bands, lane 2 and 3

7/10/2014 - Garrett Jensen.
- I ran out that PCR on a gel and there was a Band!!!! That means that there is good DNA present. I started a PCR reaction using taq polymerase and our Crispr primers to see if I can get a product for the CRISPR system. If I can then I will set it up again with phusion. We still have not received the m17 media however.

July 10th Michael Linzey Used a DNA prep kit to extract my plasmid from the DNA
- Same protocol that I have followed before
- Just followed the kit

July 14th Michael Linzey
Prepared my samples of DNA to get sequenced to make sure that the T7 spacer that we designed was there
We also helped move our lab to a new life science building

7/16/2014 - Garrett Jensen.
- On monday (7/14/2014) we moved our lab to the new life sciences building and were not able to do any work.
- I ran out the PCR attempt to amplify the CRISPR from the LMD-9 DNA that Skip made but no bands were visible.
- After talking with Dr. Grose and Desi we decided to cancel our order of the M17 media. It apparently was back ordered but the company sent a shipping document anyways. We have all the materials to make M17 media except for beef extract. Desi found a place to order it from for pretty cheap and sent the information to Dr. Grose. We were able to find ascorbic acid (vitamin C) in Dr. O'Neil's lab. Once the beef extract comes in I can grow LMD-9 and purify its DNA.

July 17th michael Linzey
Helped Mike Abboud with the Sewing PCR
- We took his successful PCR product of the sewing PCR for N. Multiformis and used a cleaning kit on it to purify it
- We also prepared a low melt gel to extract just the DNA from the sample
