Ultrathin Carbon on Quantifoil Support Film
Particle density and distribution has been widely shown to improve on the addition of an ultrathin (2-3 nm) carbon (UTC) layer to a grid. Data quality has improved for both QUANTIFOIL® Holey Carbon Films and UltrAuFoil® Gold Supports when a UTC layer is applied.
Improvements in specimen quality
Shown in the image is the structure of Photorhabdus luminescens TcdA1, a large multisubunit complex toxin, with activity against insects, whose structure was determined using images collected on QUANTIFOIL® R 2/1 grids with a 2 nm additional carbon layer6. Many biomolecules have a strong affinity for carbon, and a number of factors contribute to a resulting improvement in specimen quality:
Increased numbers of particles due to adsorption of biomolecules onto carbon prior to blotting.
Improved particle distribution due to interaction with carbon surface across the hole.
Reduction in the number of particles adopting a preferred orientation.
