FCS-Based Sensing for the Detection of Ochratoxin and Neomycin in Food
In this work, we present an advanced fluorescence assay for the detection of traces of ocratoxin A and neomycin in food. The described assay is based on measurement of the fluctuations of the fluorescein-labeled analytes by a focused laser beam in the absence and in the presence of the specific antibodies anti-analytes. A competitive assay based on the utilization of unlabeled analytes was developed. The obtained results indicated that the combination of high-avidity IgG antibodies together with an innovative fluorescence immunoassay strategy resulted in the detection limit of 0.0078 ng and 0.0156 ng for ochratoxin A and neomycin, respectively.

More about this publication?
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
