Incubate for 2–5 minutes at 37℃ until individual single cells start to round up. Suitable for use in preparation of – Cultivate the cells on feeder cells until the day of the experiment. If the cells are clumped they cause several problems such as: • A large clump will clog the cell sorter nozzle tip which causes a delay and may contaminate the collection tubes. Accutase is useful for cell detachment and for preparing single-cell suspensions from clumped cell populations for sub-culturing cells, analytical studies, and for accurate cell counting. 1 ± 1. ; Synonyms: Cell detachment solution at The net result is that the final single-cell suspension will not provide accurate representation of the cell-type proportionality present in the initial tissue. Dissociate the clumps with Accutase into a single cell suspension – Cultivate the cells on feeder cells until the day of the experiment. The prolonged culture did not significantly alter the composition of the cell suspension obtained after Accutase digestion; the additional time in culture, however, reduced the yield of single cells obtained using either papain (54. Kanton S et al. Accutase is gentle on cells; viability was 97 ± Cells are the fundamental units of organisms. Long incubation times are likely to influence gene expression, which will confound interpretations on the obtained data.
