SUMMARY — Myosin and actin were isolated from rabbit skeletal muscle. The gelation of myosin, actin and actomyosin, as well as of heavy and light meromyosins derived from myosin by trypsin treatment, by heat was studied in various systems. The data indicate that the heat gelling properties of these protein solutions do not run parallel with those of saline model systems composed of these proteins and stroma.Actin does not exert any influence on the binding properties of the system, but when F‐actin and myosin A were both present the resulting binding properties were considerably improved. Since heavy and light meromyosins have little influence on binding properties, it may be concluded that an intact molecule of myosin is required for development of binding properties upon heating.
