The effect of adenosinetriphosphate upon actomyosin solutions, studied with a recording dual beam light-scattering photometer.

Abstract

A recording dual beam light-scattering photometer is described which permits kinetic studies involving changes in turbidity, and which is not, as are single photocell instruments, affected by the errors due to the attenuation of the scattered light within the turbid medium. With this method, a renewed study has been made of the physical changes occuring in actomyosin under the influence of ATP.
