cryo-EM vitrification conditions Cryogen ETHANE；Thin filaments were reconstituted by first mixing F-actin and tropomyosin to final concentrations of 10 uM actin and 7 uM tropomyosin. Just before applying 1.5 uL actin-tropomyosin to a freshly glow discharged holey-carbon grid, the surfactant octyl B-D-glucopyranoside was added to the protein solution to a concentration of 12 nM. The grid sample was manually blotted for 1 second and a 1.5 uL drop of 7.5 uM myosin-S1 sub-fragment was then applied to the blotted grid sample. The sample was immediately blotted for 4 seconds and plunge-frozen in liquid ethane.
