From Bench to Bioreactor—Scalable, High-Yield Systems Tailored to Your Molecule
Why Choose Elise for Upstream?
At Elise Biopharma, upstream is not a room full of reactors—it’s a governed system where biology, transport physics, and analytics are wired together from day one. Whether you’re producing microbial enzymes, antibody fragments, cytokines, Fc-fusions, SAAV-rich designer proteins, or difficult membrane targets, our teams design scale-credible processes that travel cleanly from shake flask to 20,000 L stainless steel without drama. Because we operate microbial, mammalian, and hybrid platforms, you don’t get forced into a chassis—you get the best-fit system, proven by side-by-side data and stress testing.
Microbial, Mammalian, and Hybrid Systems
We run E. coli (BL21(DE3), K-12 ΔendA/ΔrecA, SHuffle/Origami), Pichia pastoris/Komagataella (GS115, AOX1, GAP, and humanized glyco-strains), Bacillus and Corynebacterium for secretion or low-LPS needs; and CHO-S/CHO-K1, CHOZN®, HEK293 for antibodies, Fc-fusions, and complex biologics. When the target benefits from dual-track development, we execute hybrid programs (e.g., microbial expression for screening and analytics + mammalian for clinical drug substance) to compress timelines and de-risk late pivots.
Fast Track from Gene to GMP—With Physics in the Loop
We shorten the path to IND/CTA by parallelizing construct work, micro-DoE, PAT model training, and early DSP scouting. As the process scales, digital twins and model-predictive control (MPC) keep oxygen transfer, heat removal, and carbon flux where CQAs behave. Thus, the same control narrative that wins at 2 L is already rehearsed for 2,000 L and beyond.
Smart Design, Data-Rich Optimization
Every campaign is structured around high-resolution telemetry (capacitance, off-gas MS, Raman/FTIR), statistical DoE (Plackett–Burman, CCD, RSM), and AI-assisted yield modeling with uncertainty. We don’t just pick a “best” setpoint; we define the operating envelope—the defendable window your QA and regulators will approve.
Core Capabilities
Feasibility & Early Expression
- Sequence & vector engineering: codon harmonization (not just optimization), RBS/5′-UTR tuning, signal peptide libraries (PelB, DsbA/OmpA) for periplasmic routes, secretion carriers when DSP wins.
- Host panel screening: BL21(DE3)/T7, leak-suppressed tox variants, SHuffle/Origami for oxidizing cytosol, Pichia AOX1 vs. GAP, CHO-S/K1, HEK transient vs. stable.
- Microscale to mesoscale: 24–96 deep-well, micro-bioreactors (10–250 mL), and high-throughput 2 L discovery pods with online pH/DO and modular feed control.
- Developability readouts: SEC-MALS for aggregation, CE-SDS/icIEF for charge, LC-MS peptide maps, and quick refold screens for IB-prone constructs.
Process Optimization
- DoE & Bayesian optimization: map factor interactions (temperature, pH, DO, µ-trajectory, osmolality, feed carbon/nitrogen) with response surfaces for titer, specific productivity, and quality attributes.
- Media & feed design: exponential vs. µ-stat feeds; amino-acid/trace formulations for mammalian; methanol co-feeds or derepressed regimes for Pichia; glycerol/glycerol+glucose strategies for E. coli to avoid overflow metabolism.
- Oxygen & heat characterization: kLa vs. P/V curves per scale; jacket capacity and gas holdup limits; antifoam use minimized and resin-compatibility validated.
- Real-time monitoring: DO, pH, OUR/CTR, capacitance (viable cell volume), Raman metabolites (glucose, lactate, glutamine, ammonia, acetate), inline OD and viscosity when relevant.
Intensification & Modes of Operation
- Batch/Fed-batch: classic regimes with MPC-governed µ profiles to suppress acetate or lactate overflow.
- Perfusion (ATF/TFF): steady-state CHO/HEK for fragile products; retention stability modeled; viral safety overlays (inactivation windows, filter integrity).
- Repetitive fed-batch / bleed-and-feed: microbial enzymes and diagnostics where productivity and footprint matter.
- High-cell-density fermentation (HCDF): OD600>150 in E. coli with oxygen/heat budgets that hold at 1,000–5,000 L.
Scale-Up & Tech Transfer
- Hydrodynamic fidelity: precise translation of OTR, kLa, tip-speed, P/V, shear across 2, 10, 50, 200, 500, 2,000, 5,000, and 20,000 L.
- Single-use & stainless compatibility: mirrored control strategies, sparger/back-pressure tuning; mass transfer profiles proven with off-gas MS.
- Digital twin handoff: advisory→shadow→write-back MPC qualification; anchor batches at the receiving site with preserved physics and re-fit plant shell.
- Complete transfer kits: SOPs, historian tag maps, soft-sensor/MPC models, alarm logic, and validated troubleshooting trees.
Elite Add-Ons You Can Only Get Here
Precision Fermentation
- Inclusion-body mastery: micro-matrix refolds (GSH/GSSG ladders, arginine/proline, gradient vs. step dilutions), continuous diafiltration refolds, and on-column refolds with kinetics modeled so residence times scale from 10 mL to 1,000 L.
- Endotoxin-light by design: low-LPS hosts, antifoam discipline, early AEX flow-through, and LER mitigation with orthogonal bioactivity checks. IVT-pDNA targets of <0.01 EU/µg achievable and repeatable.
- Secretion paths: Bacillus/Corynebacterium for extracellular enzymes; membrane proteomics feedback to tune signal peptides and export.
Mammalian Excellence—Quality Attributes Over Hype
- Glycoform control: afucosylation via FUT8-attenuated lines; terminal sialylation via ST3GAL/B4GALT tuning; HILIC-FLD and LC-MS glycopeptide mapping; icIEF/CEX linkage to effector function.
- Perfusion with sense: retention stability models, oxygen/heat headroom accounting, and viral clearance preserved; qP maintained without drift.
- High-concentration readiness: viscosity mitigation (histidine/arginine/salt systems), interfacial-stress control, and controlled-nucleation lyo cycles guided by Tc/Tg′.
Hybrid Programs—Where Speed Meets Quality
- Microbial discovery + Mammalian DS: run expression in E. coli or Pichia for rapid screens, analytics, and epitope mapping while CHO/HEK line generation proceeds; converge on a single, audited control strategy.
- Microbial pDNA → Mammalian/LNP mRNA: RNase-controlled pDNA with supercoiled %, residuals, and ultra-low endotoxin feeding IVT and downstream LNP.
Platform-Ready and Customizable
- Plug-and-play platforms: for mAbs, fragments, enzymes, and diagnostic reagents with pre-qualified PAT models, feed recipes, and DSP skeletons.
- Bespoke workflows: for VHH nanobodies, ADC payload proteins, cytokine fusions, elastin-like polypeptides, collagen-mimetic repeats, and tough membrane targets—each with tailored refolds or secretion strategies.
Speed, Control, Repeatability—By Design
- PAT built-in: Raman/FTIR, capacitance, off-gas MS, inline UV/cond; soft sensors validated with scope, accuracy/precision, and residual-alarm thresholds.
- MPC everywhere it helps: multivariable control of pH/DO/feed/back-pressure with hard constraints and fail-safe PID fallbacks; performance indices (IAE/ISE) trended in CPV.
- Audit-ready: ALCOA+ historian, version-controlled methods, pre-agreed CPP/CQA maps, and comparability packages that read like a regulator wrote them.

Because bigger only matters when it is predictable, each tier is hydrodynamically mapped to the next before you spend a day of plant time.
What You’ll See During Execution
- Induction choreography keyed to capacitance slope and RQ inflections, not a wall clock.
- Foam control with mechanical/back-pressure bias; silicone only after resin-compatibility proof and guard-bed/CIP plans.
- Oxygen/heat budgets honored; induction forbidden inside a defined heat-headroom margin to prevent late-run collapse.
- UF/DF designed with TMP×time limits, membrane chemistry screening, and diafiltration trajectories simulated for ionic/osmotic safety.
Analytics With Teeth
- Identity & integrity: intact mass + LC-MS/MS maps for proteins; restriction and topology for pDNA.
- Purity/aggregates: SEC-MALS, CE-SDS (r/nr), SDS-PAGE, AUC when needed.
- Charge/glycan: icIEF/CEX and HILIC-FLD with site-specific MS linkage.
- Potency: enzyme kinetics (kcat/Km), BLI/SPR, and cell-based readouts as required by MoA.
- Residuals: endotoxin, HCP ELISA (platform/custom), host-cell DNA qPCR, Protein A leachables.
- Stability: ICH Q1A real-time/accelerated; forced degradation (thermal, oxidative, agitation, light) with structure–function mapping.
Tech Transfer and CPV—No Surprises
- Transfer on rails: twin physics preserved; plant shell re-fit on anchor batches; equivalence statistics on CPP/CQAs; operator-intervention rates recorded as MPC moves to write-back.
- CPV that predicts: CQAs trended and model residuals monitored; seasonal utilities and raw-material lot switches overlaid; re-fit rules pre-agreed so drift is handled before deviations are written.
