Abstract
Differential scanning calorimetry of polymeric F-actin at pH 8.0 showed that the polymer had a concentration-independent thermal profile with a single transition temperature of 81 degrees C. In contrast, the thermal profile of G-actin was concentration-dependent, and although it resembled the F-actin profile at lower concentrations, it was found to have a more complex profile at higher protein concentrations.
摘要
在pH 8.0条件下对聚合态F-肌动蛋白进行差示扫描量热法分析表明，该聚合物具有与浓度无关的热谱，单一转变温度为81摄氏度。相比之下，G-肌动蛋白的热谱则依赖于浓度，尽管在较低浓度下它与F-肌动蛋白的热谱相似，但发现在较高蛋白质浓度下其热谱更为复杂。
