Determination of phosphotyrosine phosphatase (PTPase) activity in normal and transformed cells.

Molecular and cellular biochemistry - 11 Aug 1993

Kremerskothen J, Barnekow A

Abstract excerpt

Through the development of a new colorimetric and non-radioactive method it is possible to measure PTPase activity in cell extracts. Applying this method we were able to demonstrate that intracellular PTPase activity in chicken embryo fibroblasts increases significantly after RSV induced transformation of these cells. PTPase activity in normal and transformed cells is inhibited by microM concentrations of...
