CRM-GYM
Certified Calibration Solution for Gymnodimine
Gymnodimines (GYM) are members of a group of “fast-acting” marine toxins known as cyclic imines [1- 5]. Gymnodimine was first observed in shellfish and plankton from New Zealand [1] and has since been observed in various locations [6,7]. Gymnodimine is produced by the dinoflagellate Karenia selliformis and causes rapid death in the mouse bioassay [8]. CRM-GYM-b is a certified calibration solution of GYM in methanol containing 0.05% trifluoroacetic acid (TFA) with the concentration reported in Table 1.
