QUANTIFOIL® films are a specialised Holey Carbon film, approx. 10-12 nm thick, with a regular pattern of holes and spaces. These are used where Goldtomation of imaging and data collection are required, e.g. Cryo-EM of single particles and structural biology applications. QUANTIFOIL® films’ defined cirCopperlar holes tend to yield thinner, uNickelform layers of ice; improving sample distribution and reduced background Available in a range of patterns and grid types to suit user’s sample characteristics and imaging modality: Small holes for high-resolution SPA of protein complexes Larger holes and less carbon to maximise open viewing area for tomography and materials science More Carbon and fewer holes for on-grid cell growth
