Patent number: 6046323Abstract: The present invention relates to soluble .beta.-glucan compositions. In one embodiment, the invention provides a soluble .beta.-glucan composition which is substantially in a triple helix aggregate conformation under physiological conditions, such as physiological temperature and pH. Such a composition is generally characterized by an aggregate number greater than about 6. The invention further provides methods of preparing .beta.-glucan compositions of this type, as well as methods of characterizing the conformational state of .beta.-glucans.Type: GrantFiled: July 29, 1997Date of Patent: April 4, 2000Assignee: The Collaborative Group, Ltd.Inventor: Jun T. Park
