WebApr 13, 2024 · Heterogeneous protease biosensors show high sensitivity and selectivity but usually require the immobilization of peptide substrates on a solid interface. Such methods exhibit the disadvantages of complex immobilization steps and low enzymatic efficiency induced by steric hindrance. In this work, we proposed an immobilization-free strategy for … WebJun 1, 2024 · We therefore took advantage of experimental Fluorescence Protease Protection (FPP) assay to assess the number and localization of TM domains of MBOAT7. The FPP assay is based on the proteinase K activity after plasma membrane permeabilization conferred by digitonin. In principle, a rapid decay of the fluorescence …

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. WebDec 1, 2010 · To determine topologies of membrane proteins, a new technique, called fluorescence protease protection (FPP) assay, has recently been established. The sole requirements for FPP are the expression of fluorescent-protein fusion proteins and the selective permeabilization of the plasma membrane, permitting a wide range of cell types …
