Crystals of bovine liver catalase are recommended as an internal standard of length in the electron microscope. Absolute sizes in the magnification range of 10,000 X to 150,000 X may be determined with an accuracy of +/- 2.5% and relative sizes with an accuracy of +/- 1.5%. Based on experimental data, the principal catalase lattice spacing is 172 +/- 4 Angstroms. Lattice lines separated by half this distance are used in actual size determinations. Crystals are suspended in antibacterial solution. Sealed in 10 ml glass vial.
