title: A permanent cell viability assay using alcian blue.
abstract: The alcian blue dye exclusion method for glutaraldehyde-fixed cells has been utilized with "centrifugal cytology" to prepare permanent records of the viability of individual cells present in suspensions. The viability of spleen cell suspensions separated by linear bovine serum albumin density gradient centrifugation has been measured with this method. Combined light and scanning electron microscopy of nonviable and viable cells demonstrated membrane alterations in alcian blue-stained nonviable cells, while viable cells were spherical and displayed uniform surface features.
