title: Cellulase slide preparation of methylcellulose cultures of hemopoietic cells.
abstract: A technique is described for making slides of colonies grown in methylcellulose semisolid medium. The entire contents of a 0.5-ml culture in a 24-well plate is digested using 0.25 ml of a 1.08-mg/ml solution of cellulase dissolved in fetal calf serum. The methylcellulose is digested overnight, and the well contents are transferred to slides and are stained. Adherent colonies are recovered using a fetal calf serum solution containing trypsin and EDTA to flush any residue from the well; the recovered cells are transferred to slides and then stained. This method produces slides free of the darkly stained methylcellulose background that interferes with viewing colonies and studying individual cells.
