a comparison of the inhibition of clonal growth , the inhibition of mitochondrial respiration , and the exclusion of trypan blue by the plasma membrane after exposure to mc 540 and graded doses of light showed that mitochondrial respiration is compromised relatively early in the course of the dye-mediated photoinactivation of cells , well before the plasma membrane loses its capacity to exclude trypan blue .
