[Intraspecific variability in fractional composition of the serum proteins of the sturgeon Acipenser stellatus].
Comparative studies on fractional composition of the blood serum proteins in two sympatric populations of the sturgeon A. stellatus (South-Caspian and North-Caspian) have been made by means of polyacrylamide gel disc-electrophoresis. Serum proteins are fractionated into 13-18 electrophoretic components, the heterogeneity of proteins being somewhat higher in the North-Caspian population than in the South-Caspian one. Most pronounced differences were found in the relative content of albumins and beta-globulins. Special interest is attracted to different heterogeneity of albumins and beta-globulins (transferrins) in the two populations of the Caspian sturgeon.
