PROTECTIVE EFFECTS OF NON-IONIC SURFACTANTS AGAINST DENATURATION OF RABBIT SKELETAL MYOSIN BY FREEZING AND THAWING.

Author(s) : WATANABE T., KIBATAKE N., DOI E.

Type of article: Article

Summary

THE RATE OF MYOSIN DENATURATION IS ESTIMATED BY MEASUREMENT OF THE DECREASE IN THE CALCIUM IONS-ATPASIC ACTIVITY AND OF THE INCREASE IN POTASSIUM CHLORIDE (0.5 M). THE TWEEN 20 AND GLYCEROL, AT CONCENTRATIONS OF 2 AND 20%, RESPECTIVELY, PREVENT DENATURATION. THESE TWO SURFACTANTS HAVE A SYNERGIC ACTION AND THE USE OF 0.1% OF TWEEN 20 AND OF 1% OF GLYCEROL PRESERVES 90% OF THE ATPASIC ACTIVITY AFTER FREEZING-THAWING. (Bibliogr. int.
