The presence and some properties of DNA polymerases isolated from normal human lymphocytes, non stimulated and stimulated by phytohemagglutinin, are described. In the non stimulated lymphocytes two cytoplasmic DNA polymerases are found, one eluting from DEAE cellulose at 0.07 M NaCl (CIn) and the other at 0.13 M NaCl (CIIn). In the nuclear soluble fraction only one enzyme activity is found (NIn) which does not adsorb to DEAE cellulose. In the cytoplasm of stimulated lymphocytes only one enzyme activity is detected (CIs) which elutes from DEAE cellulose at 0.12 M NaCl. The nuclear soluble fraction contains two activities, NIs, which does not adsorb to DEAE cellulose, and NIIs, which elutes from DEAE cellulose at 0.07 M NaCl. Some properties of the different enzymes are described which indicate that NIn and NIs enzymes are clearly different from the others. © 1974.
