7.15.08
To Do:
- Come up with shortlist of DNA fragments to use in gel shift assay.
- Look for HmgR and GpxR boxes (putative boxes from Mayuree) at the HmgA/HmgR promoter (they're divergently transcribed, remember).
- Maybe write a script to help me find the boxes.
Mayuree suggested a probe, but wants to look into using two different dyes. Want to avoid quenching or FRET - look at excitation and emission spectra.
Dye | Excitation | Emission | 6-Fam Acceptor | 6-Fam Donor |
6-Fam | 494 | 518 | n/a | n/a |
CY3 | 548 | 562 | no | no |
CY5 | 650 | 670-700 | no | no |
HEX | 535 | 556 | no | no |
Iowa Black | / | / | Definitely a quencher of 6-fam | |
Joe | 520 | 548 | close, likely | no |
ROX | 585 | 605 | no | no |
TAMRA | 565 | 580 | no | no |
TET | 521 | 536 | close, likely | no |
Texas Red | 589 | 615 | no | no |
