Ran Blank (B) and two samples (1 and 2).

- 6/30/16: Ran 10uL of PCR products on 1.5% gel,ul, Cut out band with product and did gel extraction using NEB kit (20uL elution volume), put it in the freezer

Run PCR product on a gel with cut vector. Cleanup pcr product and cut vector. Cut PCR product with EcoRI and HindIII. Heat inactivate at 95C for 10 min. Cleanup cut PCR product... Ligate vector and insert and transform...Pick colonies and mini prep. Pet28a+ with only LacZ omega fragment: Amplify pet28a+ plasmids with LacZ with primers that will delete the 11-41 residues (“LacZ deletion R” and “LacZ deletion F”)...Ligate (KLD reaction)...Transform into highly competent cells Putting lacZ omega frag into submission vector: Order reverse primer which is complementary to C terminus of lacZ and has SpeI and PstI... Amplify lacZ omega frag using new primer containing SpeI and PstI and also “EcoRI and XbaI lacZ F”... Cut vector RFC10 with XbaI and SpeI... Run PCR product on a gel with cut vector. Cleanup pcr product and cut vector. Cut PCR product with XbaI and SpeI. Heat inactivate at 95C for 10 min. Cleanup cut PCR product... Ligate vector and insert and transform... Pick colonies and miniprep.

- 8/25/16: PCR purified the LacZ PCR(Ecori/HindiIII)

- 8/26/16: Digest of PCR product with EcorI and HindiIII, Run products on a 1% agarose gel, did not see any bands, Run pet28a and LacZ PCR product with EcoRI/HindiIII overnight. Set up two reactions for each plasmid

-Cannot find lacZ deletion r or lacZ deletion f in the USB or Liu lab after looking extensively. Reordering but need to come up with an alternative method of showing that part of our project works.

-Ideas: Do PLA and NASBA then digest with DNase I and run agarose gel with SYBR gold. Protein gel to detect alpha fragment. Could be improved if we had dna coding for alpha frag. Possibly even just detecting PLA directly on a gel if it is sensitive enough? It looks like as little as 16.7 nM of probe 1 linked to probe 2 (short terminator) would be detectable on an agarose gel with sybr gold (40 ng in a 20 ul reaction). The M.W. of probe 1 linked to probe 2 (short terminator) is 95652 g/mol, M.W. of probe 2 (short terminator) is 45123, M.W. of probe 1 is 50467, M.W. of 3C connector is 5742, M.W. of 2C connector is 5453, M.W. of 1C connector is 5163... For testing PLA using agarose gel and sybr gold only… We want to shoot for ~200 ng of probe 1 linked to probe 2 (short terminator) product for maximum visibility on the gel. We want an equimolar amount of thrombin, probe 1, probe 2, and the connector. They should all be 0.1 uM final conc. We want 74.03 ng of human alpha thrombin because M.W. of thrombin is 37000 daltons. Our thrombin stock is 7.9 mg/ml so we need to dilute a small part of this stock (diluted in 1X T4 DNA ligase buffer) by a factor of 100 so that we can use 0.937 uL of that diluted stock in a 20 ul reaction. In this reaction, we will also need 100.95 ng of probe 1 and 90.24 ng of probe 2 and 11.48 ng 3C connector or 10.91 ng of 2C connector or 10.33 ng of 1C connector. We will also want 2 ul of T4 DNA ligase and 2 ul of T4 DNA ligase buffer per rxn. Incubate at 37C for ? minutes. Heat samples to 70C for 10 min to heat inactivate ligase and melt connector-probe interactions, then immediately load onto 1.75% agarose gel. Run a ladder and also run 100.95 ng probe 1 alone.

- 6/14/16: Diluting all oligos to 100 uM stocks except for connectors which are 200 uM... PLA probe 1: 40 uls H2O = 100uM, PLA probe 2: 40uls H2O = 100uM, PLA linker 1C:829uls H2O = 200uM, PLA linker 2C:680uls H2O = 200uM, PLA linker 3C:632uls H2O = 200uM, Dilutions of probes and linkers to use in the solutions… Dilute a portion of all stocks 100x

- 6/14/16: Ran ligation reaction first attempt. Did not see evidence of ligation.

- 6/14/16: 10/12/16: transformed pSB1C3 into dh5a

- 6/14/16: 10/15/16: picked colonies, started cultures. Got sequencing results for lacZ in pet28, confirmed that colonies 1, 3, 4, and 5 are good (not sure about others). Found LacZ deletion F and LacZ deletion R primers. Started PCR with these primers

- 6/14/16: 10/16/16: minipreped pSB1C3, digested with EcoRI and PstI, ran gel (1.5%). Attempted ligation reaction second time. Still no evidence of ligation.

- 6/14/16: 10/18/16: Attempted ligation reaction third time. Still no evidence of ligation.
