WE NEED A T-SHIRT DESIGN!
Jennyn 13:46, 12 June 2006 (EDT): I'd love to help with this if the team needs.
06/12/06 Repeat (from 6/09/06) Transformation Lab
Sources
- Note, used 1/2 of designated source
- SAMT in PET28 1.6 μg
- BAMT in PET28 2.0 μg
- BSMT in PET28 2.0 μg
Dehydrated DNA Recovery (from paper)
- Final DNA Concentration: 1ng/μL (room for better quantification)
- Add appropriate amount of TE buffer to 1.7mL Eppendorf tubes (500μL for BAMT and BSMT; 400μL for SAMT).
- Carefully cut out paper that contains DNA and place into Eppen.
- Ensure submergence with toothpick
- Wait for 10 minutes
Transformation
- Followed chemical transformation protocol listed here.
- Cell Types Transformed:
- DH5&alpha (big clear tubes with green tape);, Top 10 (Invitrogen) (purple caps), Top 10 (Tom) (big clear tubes), BL21 (Invitrogen) (greenish brown caps)
- Used 2μL of plasmid/DNA.
- Heat shocked the BL21(DL3) cells
- 42 c for 50 seconds
- Used 500μL 2xYT media for DH5&alpha cells
- Used 500μL S.O.C. media for other 3 cells
- horizontal shaking for 60 minutes
- Plated 200μL cells
- Cell Types Transformed:
Notes
- Invitrogen Top 10 BSMT tube fell. It was put on the microfuge for a second to get the cells off the side of the tube.
- For TOP10 cells use this transformation protocol, which is similar but slightly different from the what we did previously
Updates on Research in Biosynthetic Pathways for Acid Production
- I emailed out the two referenced papers on this pathway: CA-->BA-->SA
- Unfortunately, it seems that the gene's sequence encoding the enzyme responsible for catalyzing the BA-->SA reaction is not in Pubmed. It seems that the last paper written on the enzyme was in 2000 and did not seem to have any information on sequence information.
