TRE5/GAGA 2: AGCGTCTAGAGGCTGCAGGTCGAG. This annealled upstream or the 5 TRE's but it didn't work because the 5 repeats would not amplify properly.
TRE5/GAGA 3: TCGAGAGAGAGAGCGCCGGAGTATAAAT. This anneals upstream from the TATA box in TRE5-70w and is used with TR2 to amplify the core promoter region. The PCR product ends up with a GAGA element upstream from the TATA element.
TRE/GAGA 4: AGTCGAGCTCGAGAGAGAGAGCGCC. This overlaps with
TRE/GAGA 3 and extends this the region upstream from the GAGA element so
that there is an XhoI site. The Xho1 site will link up to the 5 TRE's
in TRE-70w.
