Amplified from the yeast genome (strain W303a) by Brown iGEM using promoter definition from:

Mumberg, Muller, and Funk: http://dx.doi.org/10.1016/0378-1119(95)00037-7


Here are the primers we used:

example: spacer + biobrick prefeix + homologous to yeast genome

TEF.fwd: GTTTCTT + attacccataaggttgtttgtgacgg + agcgttggttggtggatcaag

example: homologous to yeast genome + biobrick suffix + spacer

TEF.rev: cggtcaacgaactataattaacta + tactagtagcggccgctgcag + AAGAAAC


To do whole-cell PCR, we prepared a reaction with double the normal magnesium and no template

10 ul 5x PCR buffer
6 uL 25 mM MgCl2
1 ul 20 uM TEF.fwd primer
1 ul 20 uM TEF.rev primer
1 ul 10 mM (each) dNTP mix
.25 ul Taq polymerase
31.75 ul cartridge-purified water

We took a small spot of cells off of a fresh plate of W303a with a 200uL pipette tip, and ground them against the bottom of the reaction tube with the tip. This is not the time to be dainty- the idea is to break open the cells with physical force.

We ran the reaction with the following program:
95C- 5 min
30 cycles of-[
95C- 30s
45C- 60s
68C- 2 min
]
68C- 5min

We got a faint nonspecific product that was longer than the expected product, so gel extracted the expected product before ligating onto pSB1AK3.
