beta-GLUCAN HAVING ACTIVITY FOR ENHANCING IMMUNITY AND FORMED INTO THE LOW MOLECULAR ONE

摘要

PROBLEM TO BE SOLVED: To provide a low-molecular-weight water-soluble β-glucan capable of promoting the in-vivo production of a cytokine exemplified by TNF, capable of enhancing the activities and useful for proliferation of various kinds of infectious disease and development of tumor by enhancing the productivity of antibody or the whole of immunological activities. SOLUTION: This water-soluble β-glucan formed into the low-molecular one has activity for enhancing immunity.
