摘　　要：本文介绍了应用激光多普勒电泳技术对MA737小鼠乳腺癌细胞及相应正常细胞的表面电荷进行研究测量的结果;并研究了MA737细胞的热效应.结果表明:MA737癌细胞的电泳迁移率(EPM)明显高于正常细胞的EPM(约20%).对MA737癌细胞进行高温(42.5℃)处理的结果还表明随加热时间的增长,其EPM值呈下降趋势.This paper introduced the characteristics of surface charge of the MA737 cell and the normal cell,and the heating(42.5℃) effect on the MA737 cell,using the techeniquc ofLaser Doppler Electrophoresis. It is shown that the MA737 cells EPM is apparent higherthan the normal cell's(about 20%),and the MA737 cell's EPM is lowing as prolonging theheating time.
