: I would like any info, references, pointers,... on Lactophenol Blue (Merck
: cat Nbr 13741).
: What is the dye used in this solution? (The dye is identified as C.I.
: 42780 on the bottle).
Please note that the widely used stain lactophenol blue actually contains
phenol, which is a hazardous substance. You should therefore avoid skin
contact or inhalation of vapour if you want to use this stain. At IMI we
have swapped over to using aniline blue in lactic acid, which is not
hazardous and works just as well for most purposes.
