GMO - background
Ensure compliance with EU GMO regulations (1829/2003) using CellMade’s integrated qPCR, ELISA, and LFD testing suite. High-sensitivity detection and 0.9% threshold quantification for a secure supply chain.
In the modern global food supply chain, managing Genetically Modified Organisms (GMOs) has shifted from voluntary disclosure to a critical regulatory requirement. Maintaining market access in the European Union necessitates rigorous screening to ensure compliance with strict labeling thresholds and the prevention of unauthorized transgenic events.
Within the European Union, the regulatory framework—governed by Regulation (EC) No 1829/2003 and 1830/2003—mandates the labeling of food and feed containing more than 0.9% authorized GMOs. Our analytical suite provides an audit-ready framework designed to meet EFSA standards and support Global Food Safety Initiative (GFSI) certifications.
1. Molecular Quantification: Real-Time PCR (qPCR)
CellMade™ Real-Time PCR is the "Gold Standard" for definitive GMO analysis. Unlike protein-based methods, qPCR targets stable DNA sequences (promoters, terminators, or event-specific junctions).
- Application: Quantitative threshold compliance (0.9%) and unauthorized event detection.
- Performance: Achieves a Limit of Detection (LOD) down to 0.01%.
- Key Advantage: Simultaneous quantification of the transgene relative to a species-specific reference gene for exact percentage reporting.
2. Quantitative Protein Detection: PriboFast™ ELISA Systems
The PriboFast™ ELISA provides a cost-effective, high-throughput solution for the quantification of newly expressed proteins (e.g., CP4 EPSPS in Roundup Ready® crops or Cry proteins in Bt-corn).
- Application: Quantitative screening of seeds, grain batches, and minimally processed ingredients.
- Performance: Provides precise concentration data in ng/g or ng/mg of tissue.
- Key Advantage: Faster and more economical than qPCR for large-batch raw material intake where the transgenic protein remains intact.
3. Operational Verification: PriboStrip™ LFDs
For real-time decision-making at the point of intake, PriboStrip™ Lateral Flow Devices (LFD) offer rapid immunochromatographic detection.
- Application: Raw grain truck intake, field testing, and Identity Preserved (IP) shipment verification.
- Efficiency: Provides qualitative "pass/fail" results in <10 minutes.
- Limitation: Best suited for unprocessed raw materials (seeds/leaves) where proteins are functional.
