June - Week 3

June 19th

Experimenter: Dan Korvin, Wenchen Zhao

Aim: Amplify T7 RNA polymerase gene (RNAP) and terminator gene by PCR.

Result: PCR was successful. Target bands were seen on the agarose gel.

June - Week 4

June 23th

Experimenter: Wenchen Zhao, Dan Korvin

Aim: Amplify T7 DNA polymerase (DNAP), primase/helicase (P/H), single strand binding protein (SSBP) genes by PCR. Digest terminator with E and X. Digest RNAP with E and S.

Result: NA.

June 24th

Experimenter: Ariel Ragetli

Aim: Verify DNAP, P/H, SSBP genes on agarose gel. Digest DNAP, P/H, SSBP amplicons with E and S. Ligate each digested T7 gene to digested terminator vector.

Result: DNAP, P/H, SSBP genes successfully amplified, but non-trivial amount of side products (mostly primer-dimer) appear in DNAP and P/H lanes. Four T7 genes all digested and ligated with terminator.

June 28th

Experimenter: Wenchen Zhao

Aim: Verify the ligation results on agarose gel.

Result: Multiple bands observed (non-trivial amount of side products). Target SSBP+terminator fragment with distinctive amount observed (only one lane with decent result).

June 29th

Experimenter: Jeffrey Pea

Aim: Amplify the target gene/terminator ligated sequence using four different forward primers and same VF reversed primer. Verify the PCR products on a gel.

Result: No significant bands we were looking for observed on the gel.

June 30th

July - Week 4

July 20th

Experimenter: Wenchen Zhao

Aim: Verify constructs by colony PCR.

Results: SSBP and RNAP constructs (gene + terminator) confirmed.

July 24th

Experimenter: Ariel Ragetli, Jeffrey Pea

Aim: Re-amplify DNAP and P/H by PCR followed by gel check. Ligate two digested amplicons to digested terminator. Transform two constructs into E.coli.

Results: NA.

August - Week 1

August 1st

Experimenter: Wenchen Zhao, Dan Korvin

Aim: Verify DNAP and P/H constructs by colony PCR. Digest SSBP and RNAP constructs with E and S. Digest Promoter + RBS plasmid with E and X. Transform the ligation products to E.coli.

Results: Colony PCR failed.

August 6th

Experimenter: Wenchen Zhao, Jeffrey Pea

Aim: Verify DNAP and P/H constructs (gene+terminator), SSBP and RNAP constructs (gene+terminator+RBS+promoter) using colony PCR.

Results: P/H and DNAP constructs confirmed. Bands with correct size were found on the gel after colony PCR of SSBP and RNAP constructs.

August - Week 2

August 12th

Experimenter: Wenchen Zhao

Aim: Prepare SSBP and RNAP miniprep products and send them for sequencing. Double digest P/H and DNAP constructs with E and S. Ligate digested constructs into vector digested with E and X. Transform ligation products into E.coli.

Results: NA.

August - Week 3

August 19th

Experimenter: Ariel Ragetli

Aim: Verify P/H and DNAP constructs using colony PCR. Analyze sequencing results of SSBP and RNAP complete constructs.

Results: Sequencing results are negative – no promoter/RBS found in SSBP and RNAP constructs. Colony PCR results are also negative.

September - Week 1

September 4th

Experimenter: Dan Korvin, Wenchen Zhao

Aim: Double digest DNAP, RNAP and SSBP constructs with X and P. Ligate three digested genes into RBS+Promoter plasmid digested with S and P. Miniprep P/H construct.
