Objective: To report for the first time successful plant cell culture production of Quillaja saponaria (QS)-21 having structural, chemical, and biological properties similar to the bark-extracted product.
Summary: The data demonstrate that cell culture is a sustainable alternative to natural resources to produce QS-21 as an adjuvant. In this proof-of-concept approach, it’s shown that the chemical, biochemical, and biophysical equivalence of bark extract and cell culture-derived QS-21 translate into conserved biological and adjuvant properties both in vitro and in vivo.
Usage: Pseudo cross-presentation assays (25 ng/mL Saporin).
