After isolation of plasmid DNA BBa_E0240 by the alkaline-lysis method, DNA samples were digested by the following restriction enzymes at 37 ℃ for 30 min.

ddH2O	2 µl
BBa_E0240	50 µl
EcoRⅠ	1 µl
PstⅠ	1 µl
10 x H Buffer	6 µl
	total 60 µl

After restriction enzyme digestion, samples were electrophoresed in 1% agarose gel at 100 V for 30min.

Results

DNA bands in the agarose gel.

You can see DNA band at around 800bp.

Agarose gel electrophoresis was carried out to detect the PCR products.

Then the PCR products were digested with the following restriction enzymes (at 37°C for 16 hours).

ddH2O	2 µl
BBa_E0240	50 µl
EcoRⅠ	1 µl
PstⅠ	1 µl
10 x H Buffer	6 µl
	total 60 µl

Results

DNA bands in the agarose gel.

You can see DNA band at around 800bp.

1.Extraction of DNA from the agarose gel.

2.Transformation of E. coli DH5 alpha with the plasmid pSB1C3.

Results

1. Picture of agarose gel after cutting out of the portion containing the DNA fragment.

Final concentration of the isolated DNA was 510 ng/µl.

2. Although small colonies were observed, we decided to transform the bacteria again just in case.
