Abstract

The article focuses on the analysis of protein diversity, the degree of the differentiation of watersoluble proteins at the charge and molecular weight, and also the dynamics of the relative content of the high- and low-molecular proteins at the early stages of ontogenesis of fresh-water copepod C. kolensis, the embryogenesis of which is characterized by chromatin diminution during the 4th embryo cell division. The relation between the dynamics of the formation of the protein composition and the basic stages of C. kolensis development — embryo, larva and mature definitive copepod was revealed. The fractional composition of proteins was stable at the stage of splitting, the maximal relative content of protein was at three yolk fractions, in composition of which several reserve plastic proteins in the form of protein associates were revealed. In larvas a quantity of water-soluble proteins was higher than in embryos, and the relative content of protein in the basic yolk fraction was minimal. The maximal variety of water-soluble proteins was revealed in definitive copepod.
