1. Prepare agar plate for Bti. 

  Beef extract  3.0g
  Peptone       5.0g
  Agar          15.0g
  ddH2O         1 L
  • adjust PH to 7.0
  • No antibiotic
  • Be aware of contamination

2. Plate Bti. on the medium and incubate the cultures at 30°C overnight.

(II) Clone cry11Aa from Bti. into TA vector

1. Extract genomic DNA of Bti. by liquid nitrogen.

2. Add some ddH2O to dilute the DNA.

3. Design primers 

  cry forward:  ATTCAATAAAAGGTGGAATGAATTATGGA       Tm: 53°C
  cry reverse:  GTGCTAACATGACTTCTACTTTAGT           Tm: 52.8°C

4. Find the best PCR condition by gradient PCR. 

  Anneling temperature: 51°C±10°C

3. Ligation to backbones(Psb1C3).

(V) Transform into E.coli

1. Thaw competent cells and BBa_K332011 plasmid on ice.

2. Add 2ul plasmid to competent cell and place in ice for 5 minutes.

3. Put the transformed cells into 42℃ water bath for 45 seconds.

4. Plate the cells on the appropriate media and antibiotic, such as agar plates with 25 µg/ml kanamycin.

5. Incubate the cultures at 37°C overnight.

6. colony PCR to confirm the fragment size by (prefix & suffix primers)

7. DNA sequencing:
