Studies of the equilibrium distribution of the cation dye-neutral red by actomyosin threads allowed to establish the fact that different concentrations of dye reveal the existence of different bonds with contractile proteins. Firm bonds (7.3 ccal/M) are discovered at low dye concentrations, and weaker bonds (4.5 ccal/M) are seen at higher concentrations. The contraction of actomyosin threads evoked by ATP or heating is accompanied with similar changes, i. e. by the diminishing of the maximum dye sorption within the range of low dye concentrations and by the increase in the maximum dye sorption within the range of high concentrations.
通过肌动球蛋白丝对阳离子染料中性红的平衡分布研究，得以确定不同浓度的染料与收缩蛋白存在不同键合这一事实。在低染料浓度下发现有牢固键合（7.3千卡/摩尔），而在高浓度下则出现较弱键合（4.5千卡/摩尔）。由ATP或加热引起的肌动球蛋白丝收缩伴随着类似变化，即在低染料浓度范围内最大染料吸附量减少，而在高浓度范围内最大染料吸附量增加。
