Lyo-Ready Molecular POC Reagents
Lyo-Ready Molecular Point-of-Care Reagents
Glycerol-free, high-concentration enzymes and master mixes formulated for lyophilization, ambient-temperature storage, and simple rehydration at the point of care.
What Lyo-Ready Reagents Are
Lyo-ready molecular point-of-care reagents are glycerol-free, high-concentration enzyme and master-mix raw materials designed to be freeze-dried and then stored at ambient temperature. Instead of shipping and storing liquid enzymes under cold chain, developers formulate a mix that can be lyophilized into a stable dried format, then rehydrated at the point of care to reconstitute a functional isothermal amplification or CRISPR-based detection reaction.
The value is workflow simplification. Removing glycerol means the mix can be dried down directly, avoiding a separate glycerol-removal step and the reagent loss and post-removal testing that step can introduce. Higher enzyme concentration means less reagent volume is dispensed per reaction, which leaves more room for sample and supports assay sensitivity. Together these properties are commonly used to build room-temperature-stable molecular tests for settings where a thermocycler and a freezer are not available.
Glycerol-Free by Design
Glycerol-free, high-concentration enzymes and mixes are formulated so they can be dried down directly, without a glycerol-removal processing step.
- No separate glycerol-removal step before drying
- Reduced reagent loss during processing
- No post-removal testing step required
Built for Ambient Storage
Lyophilized formats are designed to hold performance at ambient or elevated temperatures, supporting cold-chain-independent shipping and shelf life.
- Lyophilization-compatible formulation
- Ambient-temperature storage and transport
- Rehydration at the point of care
Fewer Steps to a Result
High-concentration mixes minimize the number and amount of reagents needed across protocol steps, from sample preparation to detection.
- Lower dispensed reagent volumes
- More volume available for sample input
- Compatible with colorimetric or lateral flow readout
Why It Matters for POC
Molecular point-of-care testing is valued for timely, accurate diagnosis, and its importance has been highlighted during outbreak response. Isothermal chemistries such as LAMP, RPA, and CRISPR-based detection are well suited to this setting because they run at a single temperature, which reduces device cost and complexity compared with thermal cycling. Lyophilization extends that advantage by removing cold storage from the equation.
Published work in this space shows the pattern repeatedly: premixed, freeze-dried reagents can be rehydrated for immediate use and retain high amplification and detection efficiency; lyophilized RT-LAMP mixes have been evaluated on clinical samples without prior nucleic acid isolation, with performance unaffected by prolonged storage at ambient or elevated temperatures; and freeze-dried RPA or CRISPR reagents have been integrated into single-tube and enclosed device formats for field deployment. These are research demonstrations, not delivery guarantees, but they define the design space your assay can target.

How Engagement Works
Every program starts from your assay target, sample type, and intended readout. Scope, enzyme selection, excipient screening, and validation depth are defined case by case in the project plan rather than chosen from a fixed menu.
Assay and Target Review
We review your target, sample type, intended amplification chemistry, and readout so the reagent format is matched to the assay rather than the other way around.
Glycerol-Free Formulation
Enzymes and master mixes are supplied in glycerol-free, high-concentration formats that can be dried down directly, avoiding a separate glycerol-removal step.
Lyophilization Compatibility
The formulation is assessed for freeze-drying compatibility, including excipient and buffer considerations, so the dried cake rehydrates into a functional reaction.
Rehydration and Readout
Rehydration conditions and readout format are defined for your platform, whether colorimetric, fluorescent, or lateral flow, with or without a prior extraction step.
Customization Options
Lyo-ready reagents are configured around your platform. The table below describes the parameters that are typically adjustable; the specific settings are agreed in the project scope.
Because isothermal and CRISPR-based formats differ in enzyme needs, buffer tolerance, and readout chemistry, we treat each program as its own formulation exercise rather than applying a single default recipe.
Amplification Format
Reagents are configured for the isothermal chemistry your assay uses, such as LAMP, RT-LAMP, or RPA, with optional downstream CRISPR-based detection.
- LAMP and RT-LAMP formats
- RPA and recombinase-based formats
- Optional CRISPR-based detection step
Dried Presentation
The dried format is matched to your device, from single-tube or strip formats to freeze-dried microspheres placed directly in a reaction chamber.
- Single-tube and strip formats
- Freeze-dried microsphere options
- Premixed, ready-to-rehydrate configuration
Detection and Sample Prep
Readout and sample handling are scoped together, including colorimetric or lateral flow detection and formats that avoid a conventional extraction step.
- Colorimetric readout
- Lateral flow strip readout
- Extraction-free sample handling where the assay allows
Service Scope
The table below describes what can be customized for a lyo-ready molecular POC reagent program. Each row is scoped per project after consultation; there are no fixed packages.
Where a parameter depends on your target and platform, the project plan defines the specific setting rather than the page.

Quality and Documentation
Lyo-ready programs are supported by documentation that lets your team review formulation decisions and verify performance after drying. The exact panel is agreed in the project plan.
Because the dried format is the product your device will use, functional verification after lyophilization is treated as a core checkpoint rather than an optional add-on.
Functional Assay After Drying
Dried reagent is tested in a functional amplification or detection assay to confirm it rehydrates into a working reaction.
- Post-lyophilization functional check
- Rehydration performance review
- Results documented against agreed criteria
Storage-Condition Monitoring
Stability is monitored under the storage conditions relevant to your deployment, since ambient and elevated-temperature exposure is the point of the format.
- Ambient-temperature storage assessment
- Elevated-temperature exposure where relevant

Applications
Lyo-ready reagents are commonly used where molecular testing needs to move out of the central laboratory: outbreak response, decentralized clinics, field screening, and other settings where cold chain and specialized equipment are limited.
Published demonstrations span respiratory pathogens, tuberculosis from respiratory or blood samples, and other infectious disease targets, using isothermal amplification with colorimetric or lateral flow readout. Your target and sample type determine which of these patterns is relevant.
Getting Started
Bring your target, intended sample type, amplification chemistry, and readout format. We will review the assay context and propose a formulation and validation approach scoped to your platform.
If your program is still at feasibility stage, the review can focus on whether a lyo-ready format is the right fit before formulation work begins.
FAQ
What makes a reagent lyo-ready rather than just concentrated?
Lyo-ready means the formulation is glycerol-free and compatible with freeze-drying, so it can be dried down directly without a glycerol-removal step. Glycerol-free, high-concentration mixes are designed to be lyophilized and then rehydrated at the point of care into a functional isothermal amplification or CRISPR-based detection reaction.
Do these reagents require a thermocycler?
No. Lyo-ready molecular POC reagents target isothermal chemistries such as LAMP, RT-LAMP, and RPA, which run at a single temperature and therefore do not need thermal cycling equipment. Thermal-cycling PCR and qPCR workflows are a different reagent category and are not the intended use here.
Can the dried reagent be stored and shipped at room temperature?
The format is designed for ambient-temperature storage and transport, which is the main reason developers move to lyophilization. Published work has reported that lyophilized isothermal reagents retained performance after prolonged storage at ambient or elevated temperatures, but the specific stability profile for your assay is established during project scoping and stability monitoring.
Is a separate nucleic acid extraction step always required?
Not necessarily. Some lyophilized isothermal assay formats have been demonstrated on clinical samples without prior nucleic acid isolation, using a rapid release or lysis step instead. Whether an extraction-free path is viable depends on your sample matrix, target, and sensitivity requirements, and is assessed during assay review.
How is performance verified after lyophilization?
Dried material is checked in a functional assay after freeze-drying to confirm it rehydrates into a working reaction, and stability is monitored under the storage conditions relevant to your deployment. The specific acceptance criteria and QC panel are agreed in the project plan rather than fixed in advance.
Can the same formulation support both colorimetric and lateral flow readout?
Readout format is scoped with your detection hardware. Colorimetric, fluorescent, and lateral flow readouts are all used in isothermal and CRISPR-based POC formats, and the formulation and rehydration conditions are adjusted accordingly. The right combination for your device is defined during project scoping.
