Four Differentiators

Built to remove variability from AAV development.

Our connected service model combines proprietary AAV data, suspension 293 manufacturing, chromatography-grade purification, dual-target dPCR, and a digitally coordinated laboratory workflow in one connected platform.

01Algorithm

Algorithm-driven sequence optimization

A single protein can be encoded by thousands of synonymous AAV sequences. Instead of relying on a generic codon table, we use models trained on proprietary high-throughput AAV data to predict stronger candidates.

  • Proprietary AAV data replaces one-size-fits-all codon substitution.
  • Synonymous redesign can produce expression differences of tens of fold.
  • Algorithmic multi-objective optimization balances yield, quality, and potency.

OptimizationExpression onlyMulti-objective optimization
02Purification

Chromatography-grade quality

Suspension 293 production plus chromatography-grade purification reduces iodixanol residual to <0.001% for cleaner animal-study data.

  • Serum-free suspension production reduces endotoxin and exogenous-material risks.
  • Residual iodixanol is far below conventional levels and close to undetectable.
  • Lower inflammatory, renal-toxicity, and osmotic-stress interference in vivo.

03Accuracy

Dual-target dPCR quantification

Even RUO batches include dual-target dPCR at no additional charge. This is a release standard, not a premium add-on.

  • Independent TaqMan probes cover the ITR and an expression-cassette element.
  • Genome-intact copies improve batch-to-batch consistency and reproducibility.
  • Dual targets help reveal truncated, chimeric, or deletion-containing genomes.

Faster service cycle

RUO AAV manufacturing is delivered in as little as 4-10 business days.

  • A mature manufacturing team and redesigned process shorten the production cycle.
  • Cloud-lab scheduling coordinates work without avoidable handoff delays.
  • Automated equipment accelerates execution and improves operational consistency.

FAQ

Common questions about AAV RUO manufacturing.

How is Crossilico RUO Manufacturing different from traditional CDMOs?

CDMOs focus on how to manufacture compliantly. Crossilico RUO Manufacturing is the physical endpoint of a validation closed loop: every batch includes LingXi optimization, full QC datasets, traceability, and a process parameter summary.

I already have a finalized sequence. Can I skip the optimization step?

No. Crossilico does not accept pure manufacturing orders without optimization. Every sequence goes through LingXi dual optimization before production. The optimization is included in the base workflow.

What is the difference between INVIVO Grade and NHP Grade?

INVIVO Grade is designed for cell experiments and rodent studies. NHP Grade is designed for non-human primate proof-of-concept studies, with higher purity, lower endotoxin, larger volumes, and more stringent QC.

Do you provide clinical-grade GMP manufacturing?

Crossilico focuses on preclinical RUO-grade batches. We provide a clinical transition package and can connect customers with trusted GMP manufacturing partners when the program is ready.

What process parameters do you deliver?

We provide a process parameter summary covering upstream and downstream parameters such as transfection conditions, harvest timing, purification parameters, concentration methods, and scale-up considerations.

How do I know my batch is suitable for animal studies?

Every batch undergoes safety QC, including endotoxin testing, mycoplasma testing, residual host-cell DNA testing, titer, purity, empty/full ratio, and genome integrity review. The batch release report includes the data and traceability.

What volume can I order?

INVIVO Grade typically covers 1-50 mL. NHP Grade typically covers 10-200 mL. Custom volumes are available for large projects.

Can I order multiple batches for a study?

Yes. We support multi-batch orders with batch-to-batch consistency controls and can discuss framework pricing for recurring batch needs.

What is the Triple-Plasmid Ratio DOE add-on for NHP Grade?

It is a Design of Experiments add-on that optimizes the transfection ratio of rep/cap, helper, and transfer plasmids to improve yield, empty/full ratio, and batch consistency. It delivers a design matrix, experimental results, and an optimized ratio recommendation.
