Retention of the glycocalyx after cell detachment by EGTA

SM Cox, PS Baur and B Haenelt

Chinese hamster ovary cells were examined ultrastructurally following several detachment procedures. Alterations in the surface glycoproteins were observed by using ruthenium red in the fixation procedure. Trypsin removed a major portion of the cells glycocalyx and formed spherical cellular configurations. EGTA detached cells were also spherical, however, their glycocalyx appeared to remain although redistributed over the cell surface. Kinetic studies showed no alterations in subsequent population doubling times following either detachment procedure. EGTA may thus represent the current method of choice for cell detachment if preservation of the surface glycoproteins is of interest.
