Galectin 9, which is a physiologically active substance showing an activity as lectin, is expressed in various cells and a correlationship is observed between the expression dose of galectin 9 and tumor metastasis ability. Namely, it is assumed that galectin 9 would relate to various physiological phenomena. Thus, a substance enabling the control of the production and release of galectin 9 is expected as exerting an antitumor activity, an activity of inducing antiinflammatory effect, etc. Therefore, it is required to clarify the same. It is found out that ~a galectin 9-inducing factor~ inducing the production and release of galectin 9 is contained in a certain solubilized tumor cell membrane fraction. This factor can be obtained as a concentrated active fraction with the use of fractionation by concanavalin A- adsorption, Resource QTM ion exchange column, hydroxyapatite column, etc. By using the activity of inducing galectin 9 of this factor, assay reagents, drugs, assays, etc. can be developed.

L'invention concerne la galectine 9 qui est une substance active physiologiquement présentant une activité similaire à celle de la lectine et qui est exprimée dans diverses cellules. Une corrélation est observée entre la dose d'expression de galectine 9 et une capacité de métastase tumorale. Notamment, la galectine pourrait être liée à divers phénomènes physiologiques. Ainsi, une substance permettant de réguler la production et la libération de galectine 9 est supposée exercer une activité antitumorale, une activité d'induction d'effet anti-inflammatoire etc. De ce fait, il est nécessaire de la clarifier. Selon cette invention, un <= facteur d'induction de la galectine 9 >= qui induit la production et la libération de galectine 9 est contenu dans une certaine fraction membranaire cellulaire tumorale solubilisée. Ce facteur peut être obtenu comme une fraction active concentrée au moyen de l'utilisation du fractionnement par l'adsorption de la concanavaline A, de la colonne d'échange ionique Q?tm¿, de la colonne d'hydroxyapatite etc. L'utilisation de l'activité d'induction de galectine 9 de ce facteur permet de développer des réactifs de dosage, des médicaments, des dosages etc.
