WebMix well to dissociate pellet and prevent cross-linking of individual cells. Fix for 15 min at room temperature (20-25°C). Proceed to Permeabilization step. Alternatively, cells may … WebCells are usually plated one day prior to staining in order to achieve 60-80% confluency. Fix the cells with 4% Formaldehyde for 15 min at room temperature or with 100% MeOH at -20oC for 10 min. Note: optimal fixation (both reagent and time) depends on the antigen of interest and must be optimized.
