105, mtrB Ligations/transformations results 8/18

Parts to ligated came from 8/17

We used a 2:1 molar ratio of insert to vector for all of the ligations. The ligations were all transformed into TOP10 cells.

Plasmid	Number of colonies
P105+P1'BB	2
P105+P3'BB	102
P101+P105	0
P101+P108	0
(mtrB(BB)+P97)+P108	20
(mtrB(BB)+P97)+P116	4
(mtrB(BB)+P97)+P117	13

In retrospect, it appears that all the ligations with mtrB are wrong, since the digest was actually wrong.

105 Colony PCR 08/18

The annealing temperature was 55 °C and the elongation time was 2'45" (we used Platinum Taq supermix).

Expected band size is 2475bp.

RE digests 45, 63, 97 08/18

We used the Fermentas enzymes and digested for 25'.

Lane 1: 1 kb ladder

Lane 2: P45 cut XP (876; 2079)

Lane 3: P63 cut EX (3284)

Lane 4: P97 cut SP (2091)

QPI+45 Ligations/transformations 08/18

We used the 45 just digested, so all DNA was cut with the Fermentas enzymes.

Colony PCR 08/18

The annealing temperature was 55°C and the elongation time was 2'30" for P108+45 and 2' for P116 and P117. We used the Platinum Taq SUPERmix.
