The composition and the level of heat shock (stress) proteins content were studied by the method of immunobloting in the gill epithelium cells of mussels Mytilus edulis L. from the
White sea, treated by water of different salinities. Stress proteins of about 70 and 40 kDa were revealed at Western blots. After long-term (11-14 days) acclimation to 14 and 35 ‰ the level of
Hsp70 in gill epithelium cells increased to compare with that in control mussels. Hsp70 induction was observed in the cells of isolated gills after salinity shock at 14 ‰ during 3 and 24 hours.
Key words: stress proteins, Hsp70, salinity, mussels
