Applicability of three alternative instruments for food authenticity analysis: GMO identification

Area of Science:

• Food Science
• Molecular Biology
• Analytical Chemistry

Background:

• Accurate food labeling for genetically modified organism (GMO) ingredients is crucial for consumers and regulators.
• DNA-based methods, particularly polymerase chain reaction (PCR), are standard for detecting GMOs.
• Electrophoresis is essential for analyzing PCR products in GMO detection.

Purpose of the Study:

• To evaluate the suitability of three laboratory electrophoresis instruments for detecting GMO ingredients.
• To assess the performance of Agilent Bioanalyzer 2100, Lab901 TapeStation, and Shimadzu MCE-202 MultiNA for GMO screening.
• To validate a previously established PCR-based protocol for GMO analysis across different instruments.

Main Methods:

• Utilized a previously validated polymerase chain reaction (PCR) protocol for GMO detection.
• Employed three distinct laboratory electrophoresis instruments: Agilent Bioanalyzer 2100, Lab901 TapeStation, and Shimadzu MCE-202 MultiNA.
• Analyzed PCR products generated from food samples to screen for GMO ingredients.

Main Results:

• All three instruments demonstrated fitness for purpose in screening GMO ingredients.
• Minor variations in precision and bias were observed between the instruments.
• The instruments successfully detected PCR products, confirming their applicability for GMO analysis.

Conclusions:

• The Agilent Bioanalyzer 2100, Lab901 TapeStation, and Shimadzu MCE-202 MultiNA are suitable for GMO ingredient screening using PCR.
• These instruments provide reliable results for food authenticity testing related to GMOs.
• The validated PCR protocol is robust across the evaluated electrophoresis platforms.
