[Statistical analysis of electron microphotographs of bioobjects, labelled by electron-dense mercarbide markers].

A method of statistical processing of electron micrographs of molecular objects modified by electron-dense labels containing mercury is proposed. The method allows one to study size, degree of modification and heterogeneity of objects. Application of the method for study of modified nitrogenase and its Fe-Mo containing co-factor, lysozyme, myoglobin, sodium thiomolybdate and trichlortriazine has shown the features of chemical modification and electron micrographs of these molecules. The method can be used for processing of data about complex biological objects modified by electron-dense labels.
