Soluble protein and peptide pattern from different regions of rat brain during pre- and early postnatal development

Isotachophoretic pattern from phylogenetically different regions of rat brain during pre- and early postnatal development were studied. Four main observations were made: a) The patterns were greatly similar during maturation of the respective regions studied; b) One complex of peaks disappeared or decreased in quantity during the 2nd and 3rd weeks of postnatal development; c) New peaks appeared and accumulated during the same period; d) Slight differences were observable in the different regions studied.
