Season Proof Production

QXS’s in-vitro production platform is inherently season-proof—unlike conventional tree harvesting, it operates independently of climate, geography, and growing cycles, enabling uninterrupted, year-round manufacturing of QS-21 and other high-value phytochemicals with consistent yield and purity.

Season Proof Production

Blockchain Traceability

QXS logs every custody hand-off, QC datapoint, and IoT condition onto a permissioned blockchain, forging an immutable ledger that tracks material from proprietary in-vitro cultures to finished GMP lots. This always-on provenance engine powers counterfeit defense, rapid recall, and regulator-ready compliance.

Blockchain Traceability

On-Demand Scale-Up, Minimal Footprint

QXS’s proprietary in-vitro solid-state cultures scale on demand—expanding capacity in weeks within just a few hundred m²—so clients receive the required tonnage precisely when promised. Always with ultra-low land, water, and carbon footprint.

On-Demand Scale-Up, Minimal Footprint

Technology

QXS is a plant-molecule manufacturer that propagates proprietary Quillaja saponaria clones with a patented in-vitro production method in closed, soil-free modules, zero deforestation, yielding chemically identical batches with >100 × metabolite concentration versus field trees. This season-proof process secures a continuous, shock-free flow of hig value phytochemicals, led by the QS-21 immune adjuvant for next-generation human and veterinary vaccines, plus precision AgTech inputs. Blockchain plant traceability, week-scale modular scale-up, and competitive unit economics position QXS as the sustainable, reliable pipeline of critical plant-derived molecules for pharma, vet-pharma, and agriculture.

QX-10® — Next-generation biofungicide based on Quillaja saponaria saponins.

QX-10® is a liquid concentrate formulated with standardized extracts of Quillaja saponaria (≥ 0.6 % total saponins) obtained through in-vitro cultivation and pharmaceutical-grade purification processes. Its high triterpene-saponin content makes QX-10® an effective and safe tool for both preventive and curative control of phytopathogenic fungi.

Spectrum and target crops: Botrytis cinerea (grey mould) in table grapes, cherries, berries and vegetables. Powdery mildew and scab (Venturia) in stone and pome fruit. Alternaria and Rhizoctonia in broad-acre crops and seedbeds

QS-21 — Consistent, High-Purity Adjuvant Engineered by QXS

QS-21 is a triterpene saponin fraction from Quillaja saponaria that boosts both humoral and cellular immune responses. It is a critical component in next-generation vaccines against infectious diseases and cancer. Traditional QS-21 is isolated from mature tree bark. Variations in age, soil, climate and post-harvest handling translate into fluctuating isomer ratios, potency drift and regulatory headaches.

Regulatory confidence — Consistent CQAs simplify lot-release and comparability filings. Reproducible immunogenicity — Uniform saponin composition reduces variability in pre-clinical and clinical read-outs. Secure supply chain — Continuous, non-seasonal production decouples your timeline from harvest yields or weather events.

QS-21 Vet-Grade — Cost-Efficient Adjuvant for Modern Veterinary Vaccinology

What it is
QS-21 Vet-Grade is the same immunostimulant trusted in human vaccines, now produced with our proprietary in-vitro Quillaja saponaria platform and purified to veterinary-pharma specifications. The result: a homogenous, high-potency saponin fraction that finally fits the cost and volume realities of animal health.

Lower cost per dose – predictable COGS enables QS-21 use in poultry, swine and companion-animal markets where margins are tight.
