Claim CLM-00001. 1. A composition comprising at least two iscom particles, wherein:
the first iscom particle comprises fraction A of Quillaja saponaria Molina and not fraction C of Quillaja saponaria Molina; and the second iscom particle comprises fraction C of Quillaja saponaria Molina and not fraction A of Quillaja saponaria Molina.
Claim CLM-00013. 13. A composition comprising at least two iscom particles, wherein: the first iscom particle consists essentially of fraction A of Quillaja saponaria Molina; the second iscom particle consists essentially of fraction C of Quillaja saponaria Molina; and the composition has a lower toxicity than a corresponding composition in which corresponding amounts of fraction A of Quillaja saponaria Molina and fraction C of Quillaja saponaria Molina are integrated together in iscom particles of the corresponding composition instead of separately in the first and second iscom particles.
