To design the Linker Variation Constructs, we amplified the DNA fragments LV1a, LV1b, LV2b, LV3a, LV5b and LV6 by PCR with the following protocol. (Primer are listed on our primer-page)

Contents

Results

We were able to amplify all of our constructs, each of them run on the expected size.

Gel extraction

The amplified constructs LV14,LV1b,LV2b,LV3a,LV5b,LV6a were sliced out of the gel and a gel extraction performed. Afterwards, the concentration was measured with a nanodrop.

Results

Construct Concentration in ng/µl A280/A260
LV1a 41,6 1,89
LV1b 69,4 1,86
LV2b 74,4 1,97
LV3a 72,9 1,84
LV5b 56,7 1,94
LV6a 50,7 2,05

Amplification of Backbone and indC

As we want to usethe strategy we established to detect a successful transformation by the expression of indigoidine, we amplified not only the backbone, but also the indigoidine constructs. They were amplified with both, a gibson-overhang for the short-linker-constructs and the long-linker-constructs.

Results

As we were able to amplify all af the constructs, we quantified the gained concentrations for gibson assembly.
