Cot1 Labeling

Labeling lots of Cot1 DNA for FISH experiments.

Samples:

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
