Sample

Phosphorylated, E1435Q Ycf1 mutant in inward-facing wide conformation

Specimen Preperation
Sample Aggregation State PARTICLE
Vitrification Instrument LEICA EM GP
Cryogen Name ETHANE
Sample Vitrification Details 5 microliters of sample of concentrated E1435Q (5.94 mg/mL) PKA-treated Ycf1 sample was applied to QF-1.2/1,3 Au grid. Grids were place inside of a Leica EM GP2 equilibrated at 10 degress Celcius amd 80% humidity. Following 10 seconds incubation, the side of the grid to which the sample was applied was blotted on a Whatman 1 paper (3.5 seconds) then immediately plunge frrozen in liquid ethan equilibrated at -185 degree Celcius.
