Produktmerkmale: CUT&RUN (Cleavage Under Targets And Release Using Nuclease) offers a new approach to pursue epigenetics.
CUT&RUN overcomes various downfalls of ChIP-Seq with improved workflow.
CUT&RUN-Sequencing has the advantage of being a simpler technique with lower costs due to the high signal-to-noise ratio, requiring less depth in sequencing.
CUT&RUN has the potential to replace all ChIP-based applications.

   • Add 5 µL CUT&RUN anti-DYKDDDDK antibody or CUT&RUN Positive Control or CUT&RUN Negative Control corresponding to a 1:20 dilution
   • Add 1 µL primary antibody against your protein of interest corrsponding to a 1:100 dilution to the remaining samples
   • Rotate the tubes for 2 h at RT or 4 h to O/N at 4 °C
   • Place the tubes on a magnet separator and remove the liquid carefully
   • Remove the tubes from the magnetic separator
   • Resuspend pellet with 1 mL Digitonin Wash Buffer and mix by inversion
   • Wash again



5. Secondary Antibody Binding (optional)
    If no secondary antibody is used proceed directly to pA/G-MNase-Binding.

   • Remove the tubes from the magnetic separator
   • Vortex the samples at low speed and add 100 µL Digitonin Wash Buffer per sample
   • Add 5 µL CUT&RUN Secondary Antibody corresponding to a 1:20 dilution
   • Rotate the tubes for 1 h at 4 °C
   • Place the tubes on a magnet separator and remove the liquid carefully
   • Remove the tubes from the magnetic separator
   • Resuspend with 1 mL Digitonin Wash Buffer and mix by inversion
   • Wash again



6. Protein A-MNase or Protein A/G-MNase Binding

   • Place the tubes on a magnet separator and remove the liquid carefully
   • Remove the tubes from the magnetic separator
   • Place each tube on the vortex mixer set to a low speed and add 50 µL Digitonin Wash Buffer and 2.5µL pA/G-MNase per sample
   • Rotate the tubes for 1 h at 4 °C
   • Place the tubes on a magnet separator and remove the liquid carefully
   • Remove the tubes from the magnetic separator
   • Resuspend with 1 mL Digitonin Wash Buffer and mix by inversion
   • Wash again



7. MNase Digestion and Release of pA/G-MNase-Bound Chromatin Fragments

   High Ca2+/Low Salt Chromatin Cleavage

   • Quick pulse in a table-top centrifuge (max 100 x g)
   • Place the tubes on a magnet separator and remove the liquid carefully
   • Resuspend with 1 mL Low-Salt Rinse Buffer and mix by inversion
   • Quick pulse in a table-top centrifuge (max 100 x g)
   • Place the tubes on a magnet separator and remove the liquid carefully
   • Wash again
   • Place each tube on the vortex mixer set to a low speed and add 200 µL ice cold Low Salt Incubation Buffer per sample
