In addition, the procedure is less subject to errors arising from cell clumping or size heterogeneity. Counting cells is more quickly and easily performed using an electronic counter, but live-dead discrimination is unreliable. WebCell 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 cell pellet as compared to the initial wet weight of the washed epithelium or tumor prior to cell isolation [22]. pottery barn tencel quilt twin
