How the CUT&RUN Assay Works
- Cell Permeabilization: Targeted protein-DNA complexes are immobilized on magnetic beads.
- Antibody Binding: A primary antibody specific to the protein of interest binds to its target.
- pG-MNase Activation: The enzyme is activated by calcium, precisely cleaving protein-associated DNA.
- DNA Extraction: The released DNA fragments are purified for downstream analysis.
- PCR/qPCR Detection: The cleaved DNA is amplified using real-time PCR for quantification.
Applications
