Abstract
The average branching number and cluster size in branched actin solutions with filament capping are evaluated using analytic theory and simulation methods. The average number of daughter branches per filament in steady state is much less than unity, regardless of the concentration of branching stimulant. Much more highly branched structures are obtained in the initial stages of polymerization.
摘要
使用解析理论和模拟方法评估了具有细丝封端的分支肌动蛋白溶液中的平均分支数和簇大小。无论分支刺激剂的浓度如何，稳态下每根细丝的子分支平均数量都远小于1。在聚合反应的初始阶段可获得分支程度高得多的结构。
