UltrAuFoil® Holey Gold Films

UltrAuFoil® is a holey gold film with a thickness of about 500 Å, that provides an ultrastable gold support for for biological samples in cryo-EM techniques. The movement of frozen specimens during imaging will be significantly reduced leading to better image contrast and finally to better 3D reconstructions with less data[1].

UltrAuFoil R 0.6/1 on 300 gold mesh (X-200-AU300) and UltrAuFoil R 2/2 on 200 gold mesh (X-203-AU200) are currently not available.
