WebResults: Red cells could be lysed using 0.1% Triton X-100 after brief fixation of whole blood with 2% or 4% formaldehyde. Light scatter improved as a function of formaldehyde concentration and inversely with MeOH concentration. CD3 signal intensity increased when MeOH concentration was reduced. WebIt removes water, it dehydrates the cells. This is important when mounting the cells in non-aqueous mounting medium. It denatures proteins. This way the metabolism of the cell is stopped and the cell dies. The metabolism is dependent on enzymes, which are proteins. It dissolves and removes lipids.
