Splet11. apr. 2024 · The resulting P1 were used for protein expression. For protein expression, 200 ml of Sf9 cells (2 x 10^6 cells/ml) were infected with 4 ml of P1 virus and cultured for 48-65 hr at 27°C. Cells were harvested, rinsed once in 1x PBS buffer and flash frozen in liquid nitrogen. All the kinesin-1 constructs were purified using the same protocol.

Splet21. okt. 2024 · FRET (Förster resonant energy transfer), relying upon exotic quantum effects, fixes pairs of such beacons in target proteins so that their light changes as the protein’s conformation changes. This enables a certain amount of research on protein dynamics as they shape-shift inside cells. SpletWe combined single-molecule fluorescence resonance energy transfer (smFRET) with single-particle tracking in live cells to detect the in vivo conformation of individual proteins. We site-specifically labeled recombinant SNARE proteins with a FRET donor and acceptor before microinjecting them into cultured cells.
