1. The specific antigenicity demonstrated in the alcohol extract of human gastric cancer was traced by preparing rabbit antisera against alcohol extracts of human gastric cancer, normal gastric mucosa, performing complement fixation tests of these antisera, aided by absorption tests, with chemical fraction of the extracts, and continuing the fractionation until the fraction responsible for the specific antigenicity could give a single peak in an electrophoretic pattern when submitted to electro-phoresis.
2. Two substances specific to human gastric cancer have been isolated. They are closely related with each other. Each substance is a single one (not a mixture of two or more substances), presumably consisting of phospholipid and glycolipid.
