Different glycosubstances and galactans in the albumin gland and eggs of Achatina fulica

Abstract

In saline extracts from the eggs and the albumin gland of the snail Achatina fulica 3 different forms of glycosubstances have been found by using heterophile precipitins from different sources: 1. An alkali-stable galactan reacting with the anti-galactans from Axinella polypoides sponge and from the clam Tridacna maxima (Tridacnin) and with Concanavalin A. 2. Another glycosubstance giving cross-reactions with a second precipitin from Axinella polypoides, with the lectin from Ricinus communis, with murine myeloma anti-galactan, with pneumococcus Type XIV antiserum and with Tridacnin. 3. The second precipitin from Axinella polypoides detects a third glycosubstance, which reacts with the lectins from Abrus precatorius and wheat germ (Triticum vulgaris).
