We found growth in one of our BPA enrichment cultures, and slight growth in our ethinyl estradiol cultures. We transferred these vials today.

Send off continued forward sequencing for HER
PCR for Gibson assembly of PNT001 and PNT002
Gel and PCR purification of PCR products
Analysis of sequencing results from yesterday
Transfer DDT and nonylphenol cultures to new media
Transform mCherry ([http://partsregistry.org/Part:BBa_J06702 J06702]), Lac Promoter ([http://partsregistry.org/Part:BBa_R0010 R0010]), double terminator ([http://partsregistry.org/Part:BBa_B0014 B0014] and [http://partsregistry.org/Part:BBa_B0015 B0015]) and Tet Promoter ([http://partsregistry.org/Part:BBa_R0040 R0040])for creation of glycerol stocks
Results
Sequencing: All biobricks showed correct sequence except T7 Polymerase
PCR of parts for pNT001 and pNT002(BioBricks + primers for Gibson): From left to right: 1 ladder; 2 blank; 3 [http://partsregistry.org/Part:BBa_R0010 R0010]; 4 [http://partsregistry.org/Part:BBa_K123000 K123000]; 5 [http://partsregistry.org/Part:BBa_B0014 B0014]; 6 [http://partsregistry.org/Part:BBa_R0040 R0040]; 7 [http://partsregistry.org/Part:BBa_K123001 K123001]; 8 [http://partsregistry.org/Part:BBa_B0015 B0015]
Ran a gel of the PCR products. Strangely, lanes 3 and 4 show no DNA. We will repeat the PCR of lanes 3-5 and Gibson assemble pNT001 ([http://partsregistry.org/Part:BBa_R0010 R0010], [http://partsregistry.org/Part:BBa_K123000 K123000], [http://partsregistry.org/Part:BBa_B0014 B0014]) later in the week.

Redo PCR of [http://partsregistry.org/Part:BBa_R0010 R0010] and [http://partsregistry.org/Part:BBa_K123000 K123000]
Analyze sequence of ER, design new primer for continued sequencing
Plan experiments using pNT001 and pNT002
Results
PCR of parts for pNT001(BioBricks+primers for Gibson): 1 ladder; 2 blank; 3 [http://partsregistry.org/Part:BBa_R0010 R0010]; 4 [http://partsregistry.org/Part:BBa_K123000 K123000]; 5 [http://partsregistry.org/Part:BBa_B0014 B0014]; 6 primers from lane 3 for negative control
Estrogen receptor ([http://partsregistry.org/Part:BBa_K123003 K123003]) sequencing is back. Again, the translation is right, but the bases don't match. The stop codon is not in this read. We will keep sequencing.
[http://partsregistry.org/Part:BBa_B0014 B0014] was not amplified in PCR. We will PCR this part and primers again, as the PCR from June 28 has a rather low concentration to be used for Gibson Assembly.

Miniprep 5 K145001 cultures and send them off for sequencing before noon
Make glycerol stocks of mCherry ([http://partsregistry.org/Part:BBa_J06702 J06702]), Lac Promoter ([http://partsregistry.org/Part:BBa_R0010 R0010]), double terminator ([http://partsregistry.org/Part:BBa_B0014 B0014] and [http://partsregistry.org/Part:BBa_B0015 B0015]) and Tet Promoter ([http://partsregistry.org/Part:BBa_R0040 R0040])
Ask Joe if we need to PCR plasmid or if he has linear plasmid
If we need to linearize: Borrow plasmid primers and plasmid, do PCR. Repeat failed PCR (Primers 9 and 10 and DNA B0014) along with it
If we don't, then repeat failed PCR
Get recipe from Joe for gibson mix and gibson protocol, make gibson mix, and run gibson reaction and transform
For gels tomorrow: Use Joe's sybr safe.
