July, 11th

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)
E1-2	Insert	18	2.5	1 XbaI	1 PstI	2.5	25
E2-2	Insert	18	2.5	1 XbaI	1 PstI	2.5	25
E3-1	Insert	18	2.5	1 XbaI	1 PstI	2.5	25

E7-2	Insert	18	2.5	1 XbaI	1 PstI	2.5	25
E8-3	Vector	20.5	0	1 SpeI	1 PstI	2.5	25

BBa_B0034	Vector	10	10.5	1 SpeI	1 PstI	2.5	25

Reactions were incubated at 37°C for three hours while two medium-size agarose gels were prepared according to protocols.

In the afternoon gel electrophoresis was performed.

As shown, in figure all clones were positive, so we cut and purified the bands of interest.

After gel extraction, digested DNA was quantified:

Part	DNA (ng/μl)
E1 (X-P)	4.2
E2 (X-P)	3.8
E3 (X-P)	4.1
E4 (X-P)	3.7
E5 (X-P)	5.6
E6 (X-P)	7.8
E7 (X-P)	6.4
E8 (S-P)	3.4
BBa_C0261 (X-P)	4.8
BBa_R0040 (S-P)	7.9
BBa_B0034 (S-P)	11.0
BBa_I13507 (X-P)	6.8

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

E9	BBa_B0030 (S-P)	1	E1 (X-P)	7	1	1

E14	BBa_R0040 (S-P)	1.5	E3 (X-P)	6.5	1	1
E15	BBa_R0040 (S-P)	1.5	E4 (X-P)	6.5	1	1
E16	BBa_R0040 (S-P)	2	BBa_C0261 (X-P)	6	1	1
E17	E8 (S-P)	4.5	E5 (X-P)	3.5	1	1
E18	E8 (S-P)	5	E6 (X-P)	3	1	1
E19	E8 (S-P)	5	E7 (X-P)	3	1	1
E20	E8 (S-P)	5	BBa_I13507 (X-P)	3	1	1
E21	BBa_R0040 (S-P)	2	E5 (X-P)	6	1	1
E22	BBa_R0040 (S-P)	2.5	E6 (X-P)	5.5	1	1
E23	BBa_R0040 (S-P)	2	E7 (X-P)	6	1	1

Ligations were incubated ON at 16°C.

July, 12th

E9, E10, E11, E12, E14, E15, E17, E18, E19, E20, E21, E22 and E23 were transformed in 100 μl of TOP10 competent cells according to protocols, while E13 and E16 ligations were transformed in 100 μl of MGZ1 competent cells. Plates were incubated ON at 37°C.

July, 13th

All plates showed a lot of colonies, except for E13, E16 (one colony),while for E14, E15 no colonies were observed (probably the parts gave too high metabolic burden that prevents cells growth or because of low transformation efficiency of MGZ1 strain). Because of RFP, E21 was red, E22 and E23 a little bit less. Two colonies (where possible) were picked for each plate.
500 ml of LB with Ampicillin were prepared.
Glycerol stocks were prepared for every culture, except for E11-1, E21-2, E23-2 because they were not sufficiently grown.

July, 14th

A glycerol stock for E21-2, E23-2. E11-1 was prepared. Cultures grew overnight; plasmid purification and quantification were carried out:

Plasmid	DNA (ng/μl)
E9-1	114
E10-1	72
E11-1	78.5
E12-1	151.7
E13-1	133
E16-1	134.4
E17-1	27.8
E18-1	25.5

For E9-1, E9-2, E10-1, E10-2, E11-1, E11-2, E12-1, E12-2, E17-1, E18-2, E19-1, E19-2, E21-1, E20-2, E21-1, E21-2, E22-1, E22-2, E23-1, E23-2 PCR was performed. ??????????????????????????????????primer? da scrivere???????????????????????????????????????

In order to screen the DNA, a digestion for each ligation was performed.

DNA (μl)	H2O (μl)	Enzyme 1 (μl)	Enzyme 2 (μl)	Buffer H (μl)	Final Volume (μl)
3	18.5	0.5 EcoRI	0.5 PstI	2.5	25

Reactions were incubated at 37°C for three hours while two medium-size agarose gels were prepared according to protocols.

BBa_B0032 were transformed in 100 μl of MGZ1 competent cells to test the competence according to protocols. Plates were incubated ON at 37°C.

In the afternoon gel electrophoresis was performed.

As shown in figure, all clones were positive, except for E9-1,E17-2, E18-1, E18-2, E19-1 which didn' t show any DNA band. E9-2, E17-2, E18-2, E19-2, E20-2, E21-1, E22-2, E23-1 purification was carried out for sequencing.

Plasmid	DNA (ng/μl)

E17-2	28
E18-2	26.3

All plates showed a lot of colonies, but the plate containing MGZ1 transformed with BBa_B0032 also showed a lot of satellities.

In order to screen the DNA, digestionS for E17-1, E17-2, E18-1, E18-2 ligation were performed.

E17-2	6	15.5	0.5 EcoRI	0.5 PstI	2.5	25
