title: [Heterogeneity and polymorphism of functionally specialized blood proteins in migratory fish: case study of the North Caspian population of the Russian sturgeon during sea and river periods of life. 1. Albumins].
abstract: A comparative study of the levels of heterogeneity and polymorphism of albumins, the most important functionally specialized blood proteins, has been carried out. The albumin system of Russian sturgeon undergoes distinct changes while the fish change habitat during the spawning migration from sea to river. They are expressed as an increased level of heterogeneity, an increased content of serum albumins in fish during the river period of life as compared to the sea period, and an increased share of a slow component of albuminograms. These changes suggest a significant role of the blood albumin system in adaptation of the Caspian sturgeon migratory species to fresh water life conditions.
