With 1μg of DNA, we manage to obtain colonies with ECE112. We will check our transformation with starch plates.
Check ECE112 stock
- Single and double digest with XbaI and EcoRI
- Gel
- Lane 3 : HyperladderI
- Lane 4 : ECE112, 100mL flask, single digest with XbaI (expected size about 10,000bp)
- Lane 5 : ECE112, 100mL flask, single digest with EcoRI (expected size about 10,000bp)
- Lane 6 : ECE112, 100mL flask, double digest (expected size about 3200bp and 6,900bp)
- Lane 7 : ECE112, 10mL flask, single digest with XbaI (expected size about 10,000bp)
- Lane 8 : ECE112, 10mL flask, single digest with EcoRI (expected size about 10,000bp)
- Lane 9 : ECE112, 10mL flask, double digest (expected size about 3200bp and 6,900bp)
- Lane 10 : HyperladderI
- Results : ok

Starch plates
- Use blank plates
- Melt 100mL of Soft Agar, and add slowly 1g of starch
- Mix, boil to sterilize
- Pour on blank plate
- Put 4 or 5 colonies on each plate
- IA751 from blank plate (positive control)
- IA771 from blank plate (negative control)
- IA751 transformed with ECE112 (Cm5, 29/08)
- IA751 control (Cm5, 29/08)
- IA751 + ECE112 (Cm5, 02/09)
- IA751 + ECE153 (Cm5, 02/09)
- IA751 + ECE153 (Cm5, 29/08)
