JULY: WEEK 5

July, 25th

Red colonies were observed from E36 plates, suggesting that the transformation was successful. A colony was picked form the plate.

Digestions of previously purified plasmids were performed for ligations:

Plasmid Kind DNA (μl) H2O (μl) Enzyme 1 (μl) Enzyme 2 (μl) Buffer H (μl) Final Volume (μl)
E24-2 Insert 13 7.5 1 Xbal 1 Pstl 2.5 25
E25-1 Insert 13.5 7 1 Xbal 1 Pstl 2.5 25
E26-2 Insert 14.5 6 1 Xbal 1 Pstl 2.5 25
E27-1 Insert 12.5 8 1 Xbal 1 PstI 2.5 25

Reactions were incubated at 37°C for three hours while a small-size and a medium-size agarose gel were prepared according to protocols.

In the afternoon gel electrophoresis was performed.

After gel extraction, digested DNA was quantified:

Part DNA (ng/μl)
E24 (E-P) -
E25 (E-P) -
E26 (E-P) -
E27 (E-P) -

Previously purified plasmids carrying either E17, or E18, or E19 or E20 part were inoculated in order to amplify them for the subsequent transformation in MGZ1 cells (E' GIUSTO?):


July, 26th

Plasmids containing either E17, or E18, or E19, or E20 or E36 part were extracted with MiniPrep kit from ON saturated cultures; purified DNA was quantified with NanoDrop Spectrophotometer:

Plasmid DNA (ng/μl)
E17 20.3
E18 18.6
E19 17.3
E20 13.2
E36 17.8

Digestion of E36 part carrying plasmid was performed for ligation:

Plasmid Kind DNA (μl) H2O (μl) Enzyme 1 (μl) Enzyme 2 (μl) Buffer H (μl) Final Volume (μl)
E36 Insert 20.5 0 1 Xbal 1 Pstl 2.5 25

Digestions of previously purified plasmids were performed for ligations:

Plasmid Kind DNA (μl) H2O (μl) Enzyme 1 (μl) Enzyme 2 (μl) Buffer H (μl) Final Volume (μl)
E36 Insert 13 7.5 1 Xbal 1 Pstl 2.5 25

Reactions were incubated at 37°C for three hours while a small-size agarose gel was prepared according to protocols.

In the afternoon gel electrophoresis was performed.

After gel extraction, digested DNA was quantified:

Part DNA (ng/μl)
E36 (S-P) -

Then ligations were performed in a final volume of 10 μl:

Ligation Name Vector Vector volume (μl) Insert Insert volume (μl) Buffer (μl) T4 Ligase (μl)
E41 E36 (S-P) 4 E3 (X-P) 4.1 1 1
E42 E36 (S-P) 3.5 E4 (X-P) 4.5 1 1
