Chromatin core particles containing 146 base pairs of DNA have been found to undergo a single defined transition below 10 mM ionic strength as studied by both sedimentation velocity and tyrosine fluorescence anisotropy. A method is described for the preparation of such core particles from chicken erythrocytes with greater than 50% yield.
通过沉降速度和酪氨酸荧光各向异性研究发现，含有146个碱基对DNA的染色质核心颗粒在离子强度低于10 mM时会发生单一确定的转变。本文描述了一种从鸡红细胞制备此类核心颗粒的方法，产率大于50%。
