What we lyophilize, and how it is delivered

Any glycerol-free molecular reagent can be dried in the format your kit needs.

PCR & qPCR master mixesRT-qPCR & isothermal amplification (LAMP) reagentsDNA & RNA enzymesReaction buffers & stabilization componentsInternal controls & reference standards
Final formats

Six ways to deliver your dry reagent

Lyophilized beadsDispensed into single tubes, strips, cartridges or bulk vials.3.0–3.4 mm · 25 µL
8-tube strips, in situDried directly in the strip at your reaction volume. Add sample and run.
96-well plates, in situFor high-throughput and automated liquid-handling workflows.
Pre-filled tubes, in situSingle tubes or microtubes dried in place for single-test kits and field use.
Glass vials, in situBulk or single-use vials, stoppered after drying: enzymes, controls, calibrators.
Custom consumablesCartridges, chips and instrument-specific tubes for OEM kits.
Glass vial filled with white lyophilized reagent beads, about 3 mm in diameter, with a few beads on the bench

Every format is validated in its final container during cycle development, so the pilot lot you approve is made the same way as production.

Our freeze-dryers run continuously for many customers at once, so pilot lots and small orders are scheduled alongside other runs instead of waiting for a dedicated batch.

Same process at every scale. Pilot lots get the same cycle validation, release testing and documentation as full production runs.

Brief & acceptance criteria

Step 1 of BIORI lyophilization service: IVD project intake, defining assay, format and volume requirements
Step 1

IVD Project Intake

You share the intended use, target panel, sample type, instrument, reaction volume, required format and expected volume. We return a scoped proposal with a feasibility plan.

You provide assay briefYou receive scoped proposal

1
Step 2: component definition, listing every reagent with its lyophilization compatibility and glycerol-free substitutes
Step 2

Component Definition

Every component of the reaction is listed with its storage buffer and lyophilization compatibility. Glycerol-containing enzymes and other non-volatile stabilizers are flagged for substitution with glycerol-free equivalents.

You receive component compatibility table

2
Step 3: QC criteria definition and alignment, agreeing Ct difference, limit of detection and reconstitution time before drying
Step 3

QC Criteria Definition & Alignment

Before drying, both sides agree on what “equivalent to liquid” means: Ct difference, limit of detection, NTC behaviour and reconstitution time. These criteria become the release specification for the finished product.

You receive signed acceptance criteria

3

Formulation, drying & pilot QC

Step 4: assay and formulation integration, matching the lyoprotectant system and buffer to the customer assay
Step 4

Assay & Formulation Integration

The lyoprotectant system is matched to your assay so that active components keep their structure through dehydration, and the buffer is adjusted to rehydrate at your protocol’s final concentrations. The reformulated liquid mix is tested against your original mix before drying.

You receive lyo-ready liquid mix + wet data

4
Step 5: lyophilization cycle development with pre-freezing, primary and secondary drying validated in the final container
Step 5

Lyophilization Development

The freeze-drying cycle is built by tuning pre-freezing, primary drying and secondary drying, and validated in the final container type. Pilot beads or cakes are compared with the liquid baseline.

Typical 4–8 weeksYou receive pilot beads or cakes

5
Step 6: internal QC and stability testing of pilot lyophilized reagents on water content, efficiency, sensitivity and stability
Step 6

Internal QC & Stability Testing

Pilot material is released against the criteria agreed in step 3 on the four release tests described below. Accelerated stability starts in parallel and real-time stability continues to support your shelf-life claim.

You receive pilot COA + stability summary

6

Validation & production

Step 7: customer validation, scale-up and mass production of lyophilized PCR reagents in an ISO 13485 cleanroom
Step 7

Customer Validation & Scale-Up / Mass Production

After your validation, the process is scaled up with simulated and real material runs until performance and stability are reproducible, then locked for production in the controlled area described below.

You receive locked production process

Real-time stability

Lyophilized Reagent Stability: 18 Months at Room Temperature

Real-time data on two lyo-ready master mixes: the same batch was run as a freshly prepared liquid mix (control) and as lyophilized reagent sealed in a foil pouch under vacuum and stored at room temperature for 18 months. Acceptance criteria were ΔCt ≤ 1 and ΔRn within 10% of the control at every template level. Click a chart to enlarge.

Shipping Stress Data for Room-Temperature Transport

Heat and humidity are the two stresses a parcel meets in transit. This study applied both to beads made with our anti-hygroscopic lyoprotectant and then ran them against freshly prepared liquid mix.

Blue: freshly prepared liquid control. Red: lyophilized beads left open for 4 h at 25 °C and 20–25% RH, vacuum-sealed in foil, then held at 55 °C for 30 days. Human genomic DNA 4-plex qPCR (FAM, VIC, ROX, CY5) and HBV qPCR (FAM, VIC). Click to enlarge.

Frequently Asked Questions

Scope, costs and what to send us.

To start a BIORI OEM lyophilization project efficiently, please share:

  • Product concept & intended use (application, target market, RUO/IVD, performance goals)

  • Required format (liquid/lyophilized, singleplex/multiplex, packaging and label requirements)

  • Technical details (target list/sequence if applicable, sample type, workflow and instrument/platform compatibility)

  • Quality & compliance expectations (ISO requirements, QC items, acceptance criteria, documents needed such as COA/SDS)

  • Demand & timeline (estimated annual volume, pilot quantity, desired milestones, delivery terms)

  • Reference materials (existing formulation/specs, competitor benchmark, any available validation data)

Explore BIORI’s Molecular Diagnostics solutions and OEM Service capabilities.

Yes on both counts. Your formulation can be lyophilized as supplied. The feasibility assessment checks it for components that hinder drying, such as glycerol, and recommends a lyo-compatible substitute where needed; we then optimize the lyoprotectants, buffer system and drying cycle, and verify post-lyo performance against your liquid baseline (sensitivity, specificity, repeatability) with recommended storage and shipping conditions.

The lyoprotectants used in our service are BIORI proprietary formulations and are also available as stand-alone products for in-house development: AcuGenix Lyophilization Protectant-17 (AS212-17) for DNA systems and AcuGenix Lyophilization Protectant-156-5 (AS212-156-5) for RNA systems. Both allow the dried product to stay open for 4 hours at 20–25% RH before vacuum packing.

Free of charge: the feasibility assessment of your formulation and project, covering compatibility, excipient review, key risks and the recommended format.

Quoted per project: primer and probe verification in the lyo-ready system, cycle optimization, and evaluation or pilot lots. BIORI does not supply free lyophilized samples; evaluation quantities are included in the project quotation. There is no minimum order for production runs.

BIORI lead times depend on project complexity and material availability. As a general reference:

  • In-stock evaluation samples: typically 5–10 business days after confirming requirements

  • Customized prototype (lab scale): typically 2–4 weeks

  • Lyophilized prototype with cycle optimization: typically 4–8 weeks

We will confirm a specific timeline after reviewing your requirements, target list, and validation scope.

BIORI provides a documentation package aligned with regulated workflows, which may include:

  • COA (lot-specific Certificate of Analysis)

  • SDS (Safety Data Sheet)

  • TDS / Product Specification and storage/shipping guidance

  • Lot traceability information and key QC records (upon request)

  • Quality system statements (e.g., ISO-managed QMS) and supporting compliance files as applicable

The exact document set can be tailored based on your market, regulatory pathway, and internal QA requirements.
