Dataset: Phylogenetic survey of soluble saxitoxin-binding activity by saxiphilin


Plasma tissue and haemolymph samples from 118 species across a range of phyla were assayed for the presence of saxiphilin [3H]STX, a soluble protein which binds the neurotoxin saxitoxin. Samples of individuals per species ranged from 1 to 18 and phyla were sourced from around the world.

Effective concentrations of [3H]STX binding sites (pmol ml-¹) in plasma and tissue samples and (pmol mg-¹) are given for the species which exhibited activity, as well as the material tested (plasma, tissue, haemolypmph) and, in some cases, the geographical source.
