The histones from slime mold Physarum polycephalum and calf thymus were characterized in terms of some physico-chemical properties. The molecular weights of six principal histone fractions of Ph. polycephalum were found to be the following: P1--22 700, P3--15 700, P4a--15 000, P4b--14 300, P5--12 800 and P6--10 500. Electrophoretically homogenous histone fractions H1, H2b and H4 of calf thymus and histones P1, P3, P4b and P6 of slime mold were obtained by gel-filtration on Acrylex P-60. These findings suggest that fractions P1, P4a, P4b, P5 and P6 of slime mold Ph. polycephalum are homologus with respect to the histone fractions H1, H3, H2b, H2a and H4 of calf thymus. Only fraction P3 has no corresponding fraction in the calf thymus histones; a fraction corresponding to histone P3 of slime mold was absent.
对多头绒泡菌和小牛胸腺的组蛋白进行了一些物理化学性质的表征。发现多头绒泡菌六个主要组蛋白组分的分子量如下：P1——22700，P3——15700，P4a——15000，P4b——14300，P5——12800，P6——10500。通过在Acrylex P - 60上进行凝胶过滤，获得了小牛胸腺的电泳纯组蛋白组分H1、H2b和H4以及绒泡菌的组蛋白P1、P3、P4b和P6。这些发现表明，多头绒泡菌的组蛋白组分P1、P4a、P4b、P5和P6与小牛胸腺的组蛋白组分H1、H3、H2b、H2a和H4是同源的。只有组分P3在小牛胸腺组蛋白中没有相应的组分；不存在与绒泡菌组蛋白P3相对应的组分。
