An extract from chromatin with 0.35 M NaCl is a heterogenous class of nonhistone chromosomal proteins. On the basis of their respective electrophoretic mobilities in polyacrylamide gel, the 0.35 M NaCl extract is divided into 2 groups: the low mobility group (LMG) proteins and the high mobility group (HMG) proteins. Up to date, a lot of researches have been mainly concentrated on the latter. It is thought
