A phylogenetic study of sulphation factor activity in 26 species
The Journal of Endocrinology
|July 1, 1977
Abstract:
Somatomedin (sulphation factor) activity was measured in 26 species by a porcine cartilage bioassay. Although non-dialysable inhibitory factors were present in many species, sulphation factor activity was present in the sera of all the vertebrates studied but was absent from the invertebrates.
