Species Identification

NSIL employs a rapid seafood species identification technique using a chip-based capillary electrophoresis and species-specific protien patterns.

Seafood substitution and mislabeling have significant economic, environmental and food safety consequences. Currently, DNA-based techniques are most commonly used to detect seafood species substitution. While DNA analysis provides results with a notable degree of confidence, more widespread use of this technology is limited by high capital output, staff and analysis cost, as well as low sample throughput.

A suggested approach for improving seafood species identification validity is use of a tiered method which uses a rapid screening assay of protein profiles with Agilent’s 2100 Bioanalyzer for primary analysis and a confirmatory method on the same platform using RFLP analysis for verifying screening positives. This tiered approach to identification analysis will help ensure that seafood marketed in the USA is accurately labeled and safe.
