EZassay LAMP Reagents Independently Validated in Peer-Reviewed Study
LFD Detection 100× More Sensitive than PCR
Overview
In May 2026, a research team from Guangxi University and the Fujian Academy of Agricultural Sciences published a study in *Microorganisms* — and we found out about it the same way everyone else did. EZassay had no involvement whatsoever.
The team was developing a rapid detection method for *R. anatipestifer* (a waterfowl pathogen). They independently screened five primer sets, optimized all reaction conditions, and ultimately selected EZassay's Colorimetric LAMP Reaction Buffer (2×) and Colorimetric LAMP Enzyme Mix (25×) as the amplification core for all experiments.
No collaboration. No sponsorship. No solicited submission. This was a purely technical choice made by independent researchers evaluating reagent performance in their own workflow.
Key Performance Data
Using EZassay LAMP reagents as the amplification core, the authors constructed a complete detection system and performed systematic validation. All data below are from the published study, not EZassay's internal testing.
Parameter | Result | Notes |
|---|---|---|
Reaction time | 30 min | Isothermal at 65 °C; no thermal cycler required |
LOD (LFD) | 7.76 copies/μL | 100× more sensitive than conventional PCR (LOD 7.76 × 10² copies/μL) |
LOD (Phenol red) | 7.76 × 10² copies/μL | Naked-eye readout; instrument-free |
Specificity | 100% | No cross-reactivity with 12 common waterfowl pathogens |
Clinical sensitivity (n = 30) | 63.3% (LFD) | PCR: 56.7% |
Repeatability | 100% | 4 concentration levels; intra- and inter-assay CV = 0 |
Two Visual Detection Methods
With EZassay LAMP reagents at the amplification core, the study developed two complementary readout strategies.
Method 1 — Phenol Red Colorimetry
LAMP amplification generates H⁺ ions, lowering reaction pH. The phenol red indicator shifts from pink (negative) to yellow (positive). Result interpretation requires only the naked eye — zero instrumentation. Well-suited for field-level screening.
Method 2 — Lateral Flow Dipstick (LFD)
FAM-labeled probe hybridization followed by capture on gold-conjugated antibody strips (LFD strips sourced from Milenia Biotec GmbH, Germany). Positive: control line (C) + test line (T) visible. Negative: C line only. Adding 3–5 min post-amplification hybridization brings the LoD to 7.76 copies/μL — 100× more sensitive than PCR.
Why This Study Matters
1. Independent validation is stronger than self-reported claims.
The authors explicitly state: "The authors declare no conflicts of interest." The research team has no affiliation, collaboration, or financial relationship with EZassay. Their reagent selection was based purely on technical assessment.
2. Cross-species, cross-scenario versatility confirmed.
The study targeted R. anatipestifer (an avian pathogen), but EZassay LAMP reagents are platform-agnostic:
- Not limited to human pathogen detection
- Applicable to veterinary diagnostics, food safety, and environmental monitoring
- Customers can develop their own target-specific assays on the EZassay platform

Compliance & Data Transparency
- All performance data (LoD, specificity, clinical sensitivity) reported above are sourced from the independently published study in Microorganisms, not from EZassay's internal testing or product claims.
- The authors declared no conflicts of interest. This article does not imply that the authors endorse or sponsor EZassay products.
- EZassay LAMP reagents are general-purpose isothermal amplification reagents. Results obtained for the specific target (R. anatipestifer ompA gene) do not automatically translate to equivalent performance for other targets.
