A modified anti-roll plate as a remedy for the ill-effects of electrical charge during cryosectioning.

This report describes problems commonly encountered in cryosectioning of fragile tissues, such as jamming and scrambling of sections between knife and anti-roll plate. The electrostatic nature of the factors causing these derangements is demonstrated here using simple methods, and several modifications to the anti-roll plate surface are tested for their help in obviating these difficulties. The anti-roll plate material found to be most effective consists of a metal oxide-coated glass which is commercially available at low cost.
