title: Isolation of nuclear and cytoplasmic proteins from DT40 cells.
abstract: Nuclear and cytoplasmic proteins from DT40 B cells are extracted by serial fractionation in this protocol. The protein extracts are suitable for the detection of DNA-protein interaction, protein-protein interaction, DNase I footprinting analysis, and related techniques. This is a general protocol that was adapted as shown here to our use due to the fragile nature of DT40 cells and their nuclei.
