Abstract
The growth of sea urchin eggs is inhibited with a composition comprising a methine dye having a reduction potential equal to or more negative than -1.0 volt which is capable of being absorbed by the eggs, and an inert liquid carrier.
Claims8
A process for inhibiting the growth of sea urchin eggs comprising contacting the eggs with a growth inhibiting concentration of a methine dye in an inert liquid carrier, the methine dye (i) having a reduction potential (E.sub.R) equal to or more negative than -1.0 volt and (ii) being capable of being absorbed by the cells of sea urchin eggs.
