Cell yield can be estimated by counting trypan blue-stained samples, using a hemocytometer [11, 37].However, total colonocyte yield is determined as the final wet weight of the purified … WebA series of yeast strains dividing exponentially at 23°C were placed at 37°C and their growth and cell cycle distribution were monitored. At indicated time points, cells density was determined by hemocytometer (a–d) and cell cycle distribution was determined by staining with DAPI (e–h).
