The ReadyPrep protein extraction kit (cytoplasmic/nuclear) prepares fractions enriched in cytoplasmic and nuclear proteins from eukaryotic samples, such as cultured cells and tissues.
The ReadyPrep protein extraction kit (cytoplasmic/nuclear):
- Employs a specially formulated buffer and differential centrifugation to isolate intact nuclei (Dignam et al. 1983, Zerivitz and Akusjarvi 1989)
- Contains a strongly chaotropic extraction buffer to efficiently solubilize nuclear proteins
- Includes the components of the ReadyPrep 2-D cleanup kit to remove compounds from the extraction buffer that may interfere with IEF
