| Abstract: | Histones and non-histone chromosomal proteins were characterized in B and T human lymphocytes by means of polyacrylamide disc gel electrophoresis. It was found that while histones do not present appreciable differences in the two examined populations, non-histone chromosomal proteins exhibit distinct electrophoretic profiles. Low molecular weight proteins predominate in B lymphocytes whereas high and intermediate proteins are largely represented in T lymphocytes. The latter proteins may be related to the capability of these resting cells to proliferate under appropriate antigenic stimuli. |
