Saline Medium

Live embryos of the sea urchin, Paracentrotus lividus, release materials which decolor the yellow ion formed by the reagent DTNB (5,5′-dithiobis(2-nitrobenzoic acid)) in amounts titratable with dithiothreitol, and this decolorant activity increased to about the 32-cell stage, declining gradually thereafter. The embryos release decolorants into a saline medium only if it contains Tris buffer and little or no calcium and is adjusted to a pH below 8.
