NEW Au-flat™ Holey Carbon Grids for High Resolution Imaging


Improve your image quality and resolution with the gold alloy film that reduces particle movement during imaging


What is Au-Flat?


Au-Flat is an ultrastable Cryo-EM sample support with a 45nm holey Gold alloy film on 3 mm gold mesh grids. Au-Flat is a derivative of our patented C-Flat product.


What varieties of Au-Flat are available?


Au-Flat is offered in two configurations:


1.2 μm/1.3 μm hole pattern on 300 mesh Gold grids 2μm/2μm Hole Pattern on 200 mesh Gold grids


What are the benefits of Au-Flat over Holey Carbon Supports like C-Flat?


Better reconstructions with less data Au-Flat significantly reduces beam-induced motion during imaging compared to carbon films, improving image quality and resolution.


Biocompatible


Au-Flat features a holey Au/Pd film on a gold mesh grid, so it’s chemically inert and biologically compatible.


Durable


Au-Flat’s film is significantly stronger than carbon films and is more capable of surviving the Cryo-EM workflow including tweezer handling, glow discharge, blotting, auto-grid loading and plunge freezing.


What are the benefits of Au-Flat over other Gold Foil TEM Grids?


Fewer Mistakes


The lighter color of the Au/Pd alloy film compared to the underlying gold mesh grid makes it easy to identify the “holey” side of the grid during sample prep. This ensures the sample is deposited on the correct side and that the grid is loaded and imaged in the correct orientation.


Stronger


Au-Flat is produced with gold mesh grids that are about 6 microns thicker than typical Cryo-EM grids. This makes the grids stiffer and less likely to bend or deform. The increased thickness is fully compatible with side-entry holders as well as auto-loaders.
