Trypan Blue Solution, 0.4%, is routinely used as a cell stain to assess cell viability using the dye exclusion test. Only cells with intact membranes can effectively exclude the dye, so dead cells with compromised membranes become stained. 

Features:

1. Viable cells exclude the dye, while nonviable cells absorb the dye and appear blue
