Bioactivity Tricaine methanesulfonate (MS-222) is common used to immobilize fish for marking or transport and to suppress sensory systems during invasive procedures[1].
Invitro Tricaine methanesulfonate in powder form easily can become airborne and could become hazardous to the handler[1].Tricaine methanesulfonate (TMS) solution is photosensitive (its color changes with light exposure), although the color change does not necessarily indicate significant activity decrease and thus color should not be used to gauge degradation[1].
