Abnormal protein spots revealed by two-dimensional electrophoresis in mycoplasma-infected human fibroblasts

Abstract
Six new protein spots were detected by two‐dimensional electrophoresis in cultured human fibroblasts infected with mycoplasma. No changes were observed in other protein spots present in normal and pathological cells. After treatment with an antimycoplasma drug for a week, the new spots disappeared and the cells became negative for mycoplasma stain.
