In histochemistry TNT and TNB are both most likely to be shortenings of TNBT
= tetranitro blue tetrazolium, which is reduced to a dark blue dye by many
tissue oxidases.  [TNB might be a scrambling of NBT = nitro blue
tetrazolium, which reduces to a light blue dye.  TNB might also be an error
for TNBS = trinitrobenzenesulfonic acid, a component of some buffers.
Undefined abbreviations are often ambiguous.]
