Fluorescence protease protection fpp
WebSep 16, 2009 · Fluorescence Protease Protection (FPP) Assay. Gonads from qaIs3502 and wild-type hermaphrodites were cut, immobilized on poly-l-lysine–coated coverslips and fixed with 4% formaldehyde. They were washed with cold PBS and incubated with 1 mg/ml trypsin in PBS for 10 min at 4°C. Webtion of the mPR N-terminus, we used the fluorescence protease protection (FPP) assay, which permits the determination of membrane protein topology in living cells. FPP employs the spa-tially confined action of trypsin following digitonin treatment to permeabilize only the PM while leaving intracellular organelles intact [20] (Fig 1C).
