Relationships between the Standard Integrated Response (SIR) of the leucophores in Uca pugilator and the logarithm of the relative concentration of extracts of the eyestalks from Uca pugilator. White pigment-dispersing responses evoked by the extract pre- pared directly in saline (dots) and the ethanol-soluble fraction (solid triangles) ; white pigment- concentrating responses evoked by the extract prepared directly in saline (circles) and the ethanol-soluble fraction (empty triangles). Two types of gels, Bio-Gel P-6 (Calbiochem) and Sephadex LH-20 (Phar- macia Fine Chemicals), were used in the present study for chromatographic sepa- ration of leucophore-activating substances. The size of the Bio-Gel column was 27 X cm. The void volume of the column, as determined by filtering Blue Dextran 2000 (Pharmacia Fine Chemicals) through the column, was ml. The material to be separated on the Bio-Gel was prepared in a small volume of distilled water ( to ml) and applied to the top of the column. Distilled.
