Electron Microscopy Sciences Quantifoil Holey Gold Film R 0.6/1 on Gold 300 mesh Grid
Newly developed ultrastable gold supports for electron cryomicroscopy will reduce the movement of frozen specimens during imaging. This improves image contrast and quality leading to better 3D reconstructions with less data.
During imaging at cryo-temperatures, traditional carbon supports move, particularly at the beginning of irradiation. This movement blurs images and makes it difficult to determine the structures of small and challenging molecules.
UltrAuFoilswere designed at MRC's Laboratory of Molecular Biology by Dr. Christopher J. Russo and Dr. Lori A. Passmore.

Electron Microscopy Sciences Graphene Oxide Support film on Quantifoil R1.2/1.3, Gold, 400 mesh
Graphene Oxide (GO) support film is a super thin (<1nm), naturally hydrophilic layer placed over the support film on grids. Pre-treatment of GO Support Films is unnecessary - by default, the hydrophilic surface spreads particles evenly across the grid. A hydrophobic surface can be achieved by heating in the air.
It works well with holey carbon, lacey carbon, and Quantifoil grid types, effectively spanning the gaps. It is less expensive than graphene to produce due to complexity of graphene manufacturing and has a better background contrast than graphene resulting in higher resolution. Nearly transparent in electron beam and barely visible under optical microscopes. Regular batch checking ensures correct coverage of monomers.
Note: plasma cleaning or glow discharge will damage the support film.
Material: Gold
