Mitochondrial Protein Isolation Buffer
AMRESCO’s Mitochondrial Protein Isolation Buffer is a convenient one-buffer solution for extraction of protein from mitochondrial fractions derived from cultured mammalian cells. The simple, scalable extraction procedure requires less than an hour and involves no toxic chemicals or ultracentrifugation steps. Following cell lysis, the cytostolic fraction is separated by centrifugation from an enriched mitochondrial fraction. This separation allows the less complex set of mitochondrial proteins to be analyzed in a single sample and increases the likelihood of detecting low-abundance proteins. The mitochondrial protein fraction can be used to perform Western blotting, ELISA or other assays.
Detection of EndoG in mitochondrial protein isolated from K562 cells
Mitochondrial Protein Isolation Buffer (M328) was used to isolate mitochondrial (lanes A1, A3, B1, B3) and cytoplasmic (lanes A2, A4, B2, B4) protein fractions from K562 cells. The proteins were resolved on a 12.5% Fluorescent SPRINT NEXT GEL® (M318) for 30 minutes at 300 volts, then visualized by UV transillumination (Figure A). The proteins were transferred to PVDF and then immunoblotted for β-tubulin (lanes B1, B2) and EndoG (lanes B3, B4) using RapidBlock™ Solution (M325) (Figure B). Bands were detected using VisiGlo Plus™ HRP Chemiluminescent Substrate Kit (N219).
