Digestion, ligation, transform: 3A assembly and standard assembly both

B0030+CinR

7/9

Result:

7/15~7/19

CinR, LuxR

7/15

Ligation:

B0030+CinR (The certain content in the ependorf labeled B0030 undergone digestion was actually previously digested; thus, concentration was assumed to be low)

Transform:

Only one colony of plate(B0030-CinR) grew. CI are successfully incubated. pCI failed to grow.

7/22~7/31

Construct our circuit.

7/22

Digestion:

B0030, CI, mTagBFP, Luciferase, B0015(tt), pCin, ACin (RBS-CinR), BCin (RBS-CinR), B0030 (RBS), LuxR

Note:Because the gel for electrophoresis healed since we took away the comb too early, most of the digestion products overflew from the wells. And we almost couldn’t see the band after dyeing, so we redid the digestion step. The second time we finally got our material for ligation! But LuxR had very strange bands (too large), so we decided not use it. And retransformed it from official plasmid.

Ligation overnight at 16 degree incubator:

(1) B0030+CI

(2) B0030+mTagBFP

(3) B0030+Luciferase

(4) B0030-CinR+tt

(5) pCin+B0030-CinR

Transform:

(1) pCI (Amp, Chl): to check the drug resistance was correct.

(2) LuR (Chl)

(3) pCin (Amp)
