Saponin adjuvant
First Claim
Patent Images
1. Substantially pure saponin purified from a crude Quillaja saponaria extract wherein said pure saponin is characterized by a single predominant peak which comprises 90% or more of the total area of all peaks of a chromatogram, excluding the solvent peak, when analyzed on reverse phase-HPLC on a Vydac C4 column having 5 μ
- m particle size, 330 Å
pore, 4.6 mm ID×
25 cm L in a solvent of 40 mM acetic acid in methanol/water (58/42;
v/v) at a flow rate of 1 ml/mixture, and wherein said saponin has immune adjuvant activity and is less toxic when used as an adjuvant than said Quillaja saponaria extract.
