WebTrypan Blue Exclusion Test of Cell Viability APPENDIX 3B. BASIC PROTOCOL. The dye exclusion test is used to determine the number of viable cells present in a cell suspension. It is based on the principle that live cells possess intact cell membranes that exclude certain dyes, such as trypan blue, Eosin, or propidium, whereas dead cells do not. WebUnfortunately, after only a short exposure time of five minutes, trypan blue starts to become toxic to cells 1-3. Even viable cells are eventually stained with trypan blue, as when the dye permeates their cell membrane, they die over time (normally between 5 to 30 minutes after exposure). The toxicity of trypan blue impacts the accuracy of ...
