摘要

测定了兔骨骼肌轻肌浆网ATP水解活性和钙转运活性。比较了TRIS和HEPES两种缓冲液的效果。将TRIS滴定到HEPES肌浆网制剂中提供了TRIS抑制atp酶活性和刺激钙转运活性的证据。

Effects of TRIS and HEPES on function of rabbit muscle light sarcoplasmic reticulum.

ATP hydrolysis activity and calcium transport activity were determined on light sarcoplasmic reticulum from rabbit skeletal muscle. The effects of two buffers, TRIS and HEPES, were compared. Titration of TRIS into sarcoplasmic reticulum preparations in HEPES provided evidence for TRIS inhibition of ATPase activity and TRIS stimulation of calcium transport activity.
