FOCUS™ SubCell for the fractionation of mitochondrial, nuclear, and cytosolic soluble and membrane proteins.

• Adaptable for animal tissue
• Resulting fractions suitable for 2D electrophoresis and other applications
• Isolated mitochondria are ~90% active

FOCUS™ SubCell is designed for the total subcellular fractionation of cells and mammalian tissue into enriched fractions of nuclear, mitochondrial, cytosolic, and membrane proteins. The resulting mitochondrial fraction can be subsequently separated into heavy and light fractions by gradient centrifugation and the resulting mitochondria are >90% active and have intact inner and outer membranes. The kit includes reagents for optional steps that minimise contamination of the nuclear fraction by cytoplasmic elements.

FOCUS™ SubCell is suitable for cultured animal cells and can be adapted for animal tissues. The kit is designed for 50 preps, where one prep is equivalent to 2×10⁷ mammalian cells or 100 mg mammalian tissue.
