Cot1 Labeling
Labeling lots of Cot1 DNA for FISH experiments.
Samples:
- 5 ug Cot1 DNA
- The entire sample of Daniel:Notebook/HiResChrPaint/2014-1-13#Nanodrop Results
1. Add 100 uL DMSO to vial containing ULS dye (stable for 6 months at 4C) *For AlexaFluor 488 label using 5 uL DMSO (stable for 1 month at 4C) ***VORTEX THESE SOLUTIONS VIGOROUSLY BEFORE USE EVERY TIME! 2. Resuspend DNA in 20 uL labeling buffer (Component C) 3. Denature DNA at 95C for 5 minutes and snap cool on ice; centrifuge briefly 4. Add appropriate volume of dye to sample (see table 2); if necessary add labeling buffer to bring volume to 25 uL 5. Incubate at 80C for 15 minutes; stop the reaction by plunging the tube into an ice bath 5-1 Measure pre-column concentration using nanodrop 6. Purify using a Centri-Sep column
