Optimization of the vitrification process in cryo-EM sample preparation

The Cryo-EM V-Kit contains 10 different surfactants plus glycerol as cryoprotectant and 4 different types of Quantifoil grids. It is designed as a Vitrification Starter Kit to facilitate the search for the optimum vitrification condition and cryo-EM grid for both soluble and membrane proteins.
