Lacey carbon films are similar to the holey carbon films in that they have open areas but because of the fine lacey mesh structure they offer a greater percentage of open area in comparison (see micrograph). They provide the thinnest possible support film while maintaining adequate strength and give practically no background interference in the TEM. As much of the specimen is unsupported, these films are appropriate for use where a structure free background is of importance. Lacey carbon films are particularly suitable for studying some nanotubes, acicular crystals and biological/materials specimens.

Supplied as 25 or 50 grids in a grid box.

Lacey carbon support films can be applied to other grid sizes, material or type. Further details available on request.

Quantifoils, produced by semiconductor lithographic techniques, are 15 - 20nm thick perforated carbon films with precise, well defined hole sizes, shapes and arrays. Quantifoil support films provide a high percentage of open area in addition to minimising total specimen thickness. Object distortions arising from interactions with the support film are also reduced. They are particularly suited for cryo applications, tomography and low dose microscopy (LEEP).

Square hole, size 7 x 7m, bar width 2m, pitch 9m.

Quantifoil type: S7/2

Quantifoils are supplied as 10 grids in a grid box.

hese recently developed ultra-stable gold supports for electron cryomicroscopy reduce the movement of frozen specimens during imaging. This improves image contrast and quality leading to better 3D reconstruction in TEM tomography applications.

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

Characteristics of UltrAuFoil

• Thickness of gold foil: approx 500
• Structure of gold foil: regular square array of micrometer-sized circular holes
• Geometry: R1.2/1.3 R0.6/1 and R2/2
• Gold 300 mesh (R0.6/1 or R1.2/1.3 geometry)
• Gold 200 mesh (R2/2 geometry)
• Other types are also available

Using UltrAuFoils, designed at MRC's Laboratory of Molecular Biology by DrChristopherJRusso and DrLoriAPassmore and produced by Quantifoil Micro Tools, specimen motion can be reduced significantl
