Upstream control

Hold the culture in its narrow viability window.

Bioseon controls media prep, seed train, and production bioreactors across pH, dissolved oxygen, temperature, agitation, CO₂, and fed-batch or perfusion feed while watching VCD and titer.

Closed-loop cell culture.

Designed for mAbs, vaccines, GLP-1 and recombinant proteins, and cell and gene therapy manufacturing.

The upstream problem.

Cells grow product only when biology, chemistry, and fluid dynamics stay aligned. Feed or gas drift can reduce viability, slow VCD growth, shift titer, or create CQA risk before standard sampling catches it.

  • Narrow viability window over days or weeks
  • Delayed lab measurements for titer and quality
  • Manual feed and gas adjustments under time pressure

Control risk signals

Bioseon fuses DCS tags, PAT and Raman signals, lab data, historian context, and environmental observations into one live view of culture health.

Media and seed control.

The media-and-seed agent tracks media and buffer prep, single-use assemblies, seed-train phase, inoculum readiness, and contamination risk before production starts.

  • Composition checks against recipe and lot context
  • Seed train growth state and transfer timing
  • Readiness handoff to production bioreactor control

Media prep

Confirms recipe, material status, conductivity, pH, and hold conditions.

Seed train

Monitors expansion, viability, transfer criteria, and contamination guardrails.

Culture and feed control.

The culture-and-feed agent adjusts setpoints inside validated envelopes, using soft sensors and the twin to keep growth and productivity aligned with the target batch trajectory.

pH

Maintains acid and base correction around the cell-line window.

DO

Coordinates oxygen, gas mix, sparge, and agitation response.

Temperature

Tracks shifts for growth, production, and quality programs.

Agitation

Balances mixing, mass transfer, and shear sensitivity.

CO₂

Controls gas strategy against pH and culture state.

Feed

Optimizes bolus, fed-batch, or perfusion feed against VCD and titer.

Soft-sensing titer and VCD.

Bioseon estimates viable cell density, titer, and culture trajectory from PAT, Raman, process variables, and lab references. Operators see where the batch is heading before the next offline result.

Upstream outcomes.

VCD

Stabilized. Growth is held closer to the intended trajectory.

TITER

Increased. Feed and production phases adapt to live culture state.

DEVIATIONS

Reduced. Drift is caught earlier with explainable actions.

MEDIA

Optimized. Feed and single-use inputs are used against measured need.

Contamination guardrails around the culture.

Bioseon combines bioburden, environmental monitoring, material status, process drift, and operator context to flag contamination and deviation risk while there is still time to respond.

  • Environmental and process signal fusion
  • Seed train and media-prep risk context
  • GMP deviation record linked to batch phase

Titer and CQA sensing

Soft sensors for titer, VCD, metabolites, and quality signals.

Digital twin

Predict culture trajectory and choose control actions before drift becomes deviation.

Downstream

Carry the target batch state into harvest, capture, polish, UF/DF, and viral steps.

Pricing for upstream lines.

Start on one production bioreactor at $13,000 per bioreactor or skid per month, expand to Site at $85,000 per month, or plan Enterprise land from $700k–$8M ACV.

Best first line

Choose a high-value production bioreactor with enough historical batches to calibrate soft sensors and compare shadow-mode recommendations.

Upstream questions.

Which variables can Bioseon control?

Bioseon controls pH, dissolved oxygen, temperature, agitation, CO₂, and fed-batch or perfusion feed inside validated process envelopes.

Does it work with perfusion?

Yes. Bioseon supports single-use and perfusion environments, including cell-retention and media-exchange strategies tied to VCD, titer, and CQA risk.

How are titer and VCD watched in real time?

Soft sensors combine PAT, Raman, DCS tags, historian data, and lab references to estimate live state between offline measurements.

What happens before closed-loop control?

Bioseon runs in shadow mode, compares recommendations to operator actions, validates model accuracy, and then enables constrained action with human override.
