Procedure


Preparation of constructs to send for sequencing

Sec2, TAT3-2, TAT3-1a, CycAX and HAO constructs were prepared for sequencing. Sample preparation was performed following the indications given by the EZ-Seq service by Macrogen:

5uL of 100~150ng/ul plasmid + 5uL of 5uM primers.

An overview of the sample composition can be found in the following link: File:Construct for sequencing - Sheet1.pdf

The samples were sent to Macrogen for sequencing.

Gradient PCR for creation of Biobricks

Made a screening to find good conditions for the extraction of our constructs for subsequent ligation into BioBricks.

PCR to linearize pZA21::RFP::araBAD

Used GC buffer and 5% DMSO. Made three samples with varying concentrations of 50mM MgCl2: 0,5 uL, 1uL and 2 uL.

template: pZA21::RFP::araBAD

primers: 55a, 55b

program:

temperature time cycles
98C 2:00 -
98C 0:10 36
65C 1:00 36
72C 3:00 36
72C 5:00 -
10C hold -

colony PCR on one of the Hello Wolrd constructs to confirm it's intact

Performed colony PCR on the construct containing Sec2 to check the template is correct because our PCRs on it are not working.
