Week 21 (09/17 - 09/23/12)
Monday September 17th
Tuesday September 18th
- Team Cellulose Binding Domain:
- Primer arrived:
- Gradient-PCR with the [http://partsregistry.org/Part:BBa_K863103 CBDcex(T7)+GFP_His]-plasmid and S3N10-CBDcex_RV and S3N10-GFP_FW primer-mix. the right product appeared only at 66,5°C; Lower: wrong product; Higher: no product
- Following PCR at 66,5°C(50µL) had the wrong product (main product at 2 kbp); could be because of a different template concentration or not exact temperature.
- Alternativly took the 20 µL-tube with right product and added 0,5 µL DpnI for over-night digestion.
- Gradient-PCR with [http://partsregistry.org/Part:BBa_K863103 CBDcex(T7)+GFP_His]-template and a CBDcex_Freiburg+GFP_Freiburg-primer-mix.
- Gradient-PCR with [http://partsregistry.org/Part:BBa_K863113 CBDclos(T7)+GFP_His]-template and a CBDclos_Freiburg+GFP_Freiburg-primer-mix.
Wednesday September 19th
- Team Cellulose Binding Domain:
- Stopped over-night-DpnI-digestion of S3N10-clos-GFP_his PCR-product and cleaned up in gel. Ligated the PCR-product with itself via Blunt-end-ligation and transformed it into KRX. Plated on Select-Agar.
- Gradient-PCRs of the CDBcex(T7)+GFP-plasmid and a CBDclos(T7)+GFP-plasmid (unsequenced) with the CBDcex_Freiburg and GFP_Freiburg-compl and the CBDclos_Freiburg and GFP_Freiburg_compl primers, respectively. The CBDcex-setup showed no correct product, but the CBDclos-setup had the right bands at temperatures from 57°C to 64°C; merged the correct fractions and cleaned them up through the gel.
- Digested the cleaned up product with SpeI and XbaI and DpnI.
- Ligated J61101 and CBDclos with GFP_Freiburg and transformed it into KRX.
Thursday September 20th
- Team Cellulose Binding Domain:
- No Colonies on the S3N10-Clos-transformations-dish with the blunt-end ligation; reason: forgotten to phosphorylate the PCR-product.
- A few colonies on the dish with the CBDclos+GFP and the constitutive [http://partsregistry.org/Part:BBa_J61101 J23100 + J61101] promoter. But none of them is glowing.
