BSPP Control (Started 09/03/2013)[edit]
Dye Coupling[edit]
- Following ARES protocol
0. Dry samples in a vaccuum centrifuge
For each
1. Warm DMSO and bicarbonate labeling buffer and nuclease free water to room temperature 2. Resuspend DNA in 5 uL nfH20 3. Add 5 uL DNA and 3 uL of sodium bicarbonate buffer in PCR tube 4. Denature samples for 5 minutes at 95C, then snap cool using ice box 5. Dissolve 1 vial of reactive dye in 2 uL solvent; vortex ≥10 seconds *dye cannot be saved for later use. Use immediately! 6. Add 2 uL dye to sample 7. Incubate in the dark for 1 hour 8. Add 10 uL nfH20 to sample 9. Purify using Centri Sep column 10. Measure concentrations using Microarray setting in nanodrop
Labeling Results[edit]
ng/uL DNA | pmol/uL dye | ug DNA in 15 uL | pmol/uL DNA | dye/probe | dye/100 bp | Base:Dye Ratio (:1) | |
BSPP 1-546 | 128.6 | 4.7 | 1.9 | 3.0 | 1.6 | 1.2 | 83 |
BSPP 2-594 | 101.6 | 4.8 | 1.5 | 2.4 | 2.0 | 1.6 | 64 |
Good results, especially BSPP 2. Both of these should work well as controls, and I now have two different options/colors as negative controls.
