Lyophilized Beads for Immunoassay and Molecular Diagnostics
DCN Dx develops and manufactures custom lyophilized beads for LFA and molecular diagnostics—custom-developed for rapid rehydration, rugged handling, and seamless integration. These beads simplify reagent handling, cut costs, extend shelf life, and integrate smoothly into automated devices for better point-of-care performance.
Optimized for Point-of-Care
Lyophilized beads offer the same benefits as traditional lyophilization—long-term reagent stability
and cold chain elimination—with added advantages tailored to point-of-care diagnostics:
.01
Dissolve almost instantly
.02
Enable simple and precise sample pretreatment
.03
Integrate easily into automated formats like microfluidic cartridges or PCR tubes
Broad
Compatibility
with Diagnostic
Reagents
DCN Dx can lyophilize a wide range of materials into bead format, including:
Buffers
Enzymes
Antibodies
Antigens
Controls
Nanoparticles (gold, latex,
fluorescent particles)
We support bead volumes from 5–35 µL and can produce up to 40,000 beads per run.

Designed to Work
in Your Device
Our scientists and engineers work
collaboratively to align bead characteristics—
such as diameter, volume, robustness, and
rehydration profile—with the device’s fluidics
and format constraints. We develop wet assays
first, then transition to lyophilized formats,
integrating directly into your final product to
ensure performance and compatibility.
