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

July, 27th

E37, E38, E39, E40, E41, E42, E17, E18, E19 and E20 were transformed in 100 μl of MGZ1 competent cells according to protocols. Moreover a plasmid containing BBa_B0032 was transformed in order to test the transformation efficiency. Plates were incubated ON at 37°C.



July, 28th

Colonies grew in every plate. Infact both 17-2, E18-2, E19-2 and E20-2 parts, whose DNA was recovered after MiniPrep extraction kit, both E37, E38, E39 and E40 parts showed grown colonies. We picked two colonies from all parts. As regards to E41 and E42 parts, we resolved to let them still grow.
Plate with BBa_B0032 showed 9 colonies. The corresponding efficiency results 9/4 [1/ng] = 2250 [1/μl]
