Dye Coupling Test and Gel Quantification
Purpose: Test dye coupling reaction, specifically the purification step, to ensure proper dye-coupled DNA is being captured. Two samples chosen from Gel Quantification (4/10/13). Oligos coupled to appropriate dye.
Dye Coupling Reaction
1. Thaw out oligos, sodium bicarbonate solution, DMSO Use thermo device on Noi's desk to heat DMSO, sodium bicarb to 42 C 2. Add 2.5 uL DNA, 1.5 uL sodium bicarbonate to 0.2 mL eppendorf 3. Denature DNA by incubating at 95 C for 5 minutes, followed by snap cooling on ice 4. Thaw out dyes (they are in big -20C) and resuspend in 2.2 uL DMSO Use dyes immediately, they do not store 5. Add 1 uL of appropriate dye to oligo set (see below) Chose V4S2 and V6S2 because of high dna content so I only had to use one dye (Alexa 546)
Probe | Alexa Dye |
V4S1 | 488 |
V4S2 | 546 |
V4S3 | 594 |
V4S4 | 647 |
V6S1 | 488 |
V6S2 | 546 |
V6S3 | 594 |
V6S4 | 647 |
6. Incubate reaction in the dark for 1 hour 7. Column purify using ssDNA kit from Zymo
Urea Gel Quantification
Set up samples according to following table
Sample | Low Mass Ladder | V4S2 w/Probe | V6S2 w/Probe | V4S2 w/o Probe | V6S2 w/o Probe | V6S1 w/o Probe |
uL sample | 0.5 | 0.5 | 0.5 | 0.5 | 0.5 | 0.5 |
uL TBE | 5.5 | 5.5 | 5.5 | 5.5 | 5.5 | 5.5 |
uL 2X buffer | 6 | 6 | 6 | 6 | 6 | 6 |
