Cryo Immuno Diamond Knife

The first cryo knife with a diamond platform, guarantees the best possible sectioning for cryo-immunochemistry.

The diamond platform guarantees easy and gentle section collection. Sections are collected directly from the diamond surface using a loop and a sucrose/methylcellulose droplet (Refs. Liou, Peters).

The 35° cutting angle leads to a considerable reduction in mechanical stresses and therefore to improved structure preservation in sucrose-protected samples.
