The "Colony PCR # 21 of rd29A in pSB1C3 iGEM VEctor" gel analysis was successful for 1 (colony PCR #21) out of 45 colonies showed an rd29A band at ~836bp.(Band is shown in the lane labeled #21).

- Sequenced Colony PCR # 21

Christian
- Sequencing of DREB1C_3 in pSB1C3 had 0 mismatches and was submitted as part BBaK414007
- 24 colonies selected from DREB1C/YFP transformation and run in colony PCR using custom DREB1C primers
- Products of PCR reaction run on a 0.8% agarose gel

Band at ~500 bp for colony 24
- Colony 24 was the only positive result
- Colony 24 DREB1C/YFP construct was sent for sequencing

Matthew
- Submitted 35S-GFP to iGEM

Richard and Nick
- Performed diagnostic digests on fragments that could potentially be Cd2+ promoter; no fragments yielded positive digestion patter...back to the drawing board

Week of October 24-30:

Elaine
- Added rd29A (pSB1C3) into the registry
- Submitted rd29A (pSB1C3) through the mail.
