Investigation of the GEM release mechanisms from PTK7-GEMs. The profile of PTK7-GEMs release from A Crude cell lysate (untreated by inhibitors) or B Lysate of cells treated with phosphatase inhibitors, The DNA maximum absorption peak was measured at 260 nm. C Cumulative release of GEM when PTK7-GEMs were incubated with crude cell lysate, phosphatase inhibitor-treated cell lysate, buffer at pH 5.5, 10% FBS and 10 ⋅ 10− 3 м GSH respectively
