  • Take out the inoculated RFP PSB1C3 (1,2,3,4) at 9:00am
  • Centrifuge the RFP PSB1C3 (1,2,3,4) for 5 minutes, using 3500 rpm speed.
  • Miniprep :

Plasmids were extracted using Gene Tech GTpure Plasmid Miniprep Purification Kit. DNA then eluted in 50 μL DE Buffer (2 times)

  • Nanodrop :

Use DE Buffer as Blank

  • Digestion :

EcoRI-HF & PstI-HF
Use Cutsmart buffer
Digestion Composition :
- 1 ug DNA (1000 ng)
- 2 uL of Cutsmart buffer
- 0.5 uL of EcoRI-HF
- 0.5 uL of PstI-HF
- ddH2O = Adjust volume to 20 uL
Incubate for 1 hour, 37 degree Celcius.

  • Gel Electrophoresis :

0.8% Agarose Gel, 20 ml, 6 wells

WELL 1 (LADDER):
- 1 uL Loading Dye
- 1 uL GenRuler 1 kb Ladder
- 8 uL ddH2O

WELL 2 (NEGATIVE CONTROL): - 1 uL of Uncut Plasmid RFP-PSB1C3(2) (124.8 ng/lane)
- 1 uL Loading Dye
- 8 uL ddH20

WELL 3-6 (DIGESTION PRODUCT)(1ug/lane):
- 20 uL of DNA
- 2.2 uL of 10X Loading Dye

  • Gel Photo

Ladder - Uncut RFP-PSB1C3 - EcoRI-HF and PstI-HF digested RFP-PSB1C3 (1-4)


  • Gel Extraction & Purification

Insert and backbone were extracted out from the gel using Favorgen FavorPrep GEL/PCR Purification Kit. The DNA is then eluted in 50 μL of Elution Buffer

  • Nanodrop
