Sample

POL II-DNA-RNA

Specimen Preperation
Sample Aggregation State PARTICLE
Vitrification Instrument ?
Cryogen Name ETHANE
Sample Vitrification Details GRIDS WERE GLOW- DISCHARGED FOR 20 S BEFORE DEPOSITION OF 4 MICROLITERS SAMPLE AND INCUBATED FOR 30 S. GRIDS WERE WASHED TWICE WITH 4 MICROLITERS DISTILLED WATER, BLOTTED, AND VITRIFIED BY PLUNGING INTO LIQUID ETHANE WITH A MANUAL PLUNGER.
