Abstract

Chloramphenicol (CAP) is a once widely used antibiotic, which is able to cause great harm to human health, is banned in some countries or organizations such as China, USA and the European Union for animal breeding. Because CAP in pig hair degraded slower and had amount of residues, pig hair could be used as the target to detect CAP residues. In this study, a competitive lateral flow immunoassay (LFIA), whose label was aggregation induced emission fluorescent nanobeads (AIEFN), was firstly developed for the detection of CAP in pig hair samples. It exhibited a low limit of detection (0.001 μg/kg) and a broad linear range (0.0025–0.32 μg/kg). The recovery rate and coefficient variation with spiked pig hair samples were 88.50%–106.17 % and 1.01%–7.37 %, which indicated good accuracy of this assay. The result of AIEFN-LFIA for the detection of CAP in pig hair was consistent with that of liquid chromatography-mass spectrometry. This assay was rapid with the total detection duration of about 20 min. AIEFN-LFIA was able to be used for rapid, sensitive, accurate and convenient detection of CAP residues in pig hair samples.

期刊介绍： The journal''s title Analytical Biochemistry: Methods in the Biological Sciences declares its broad scope: methods for the basic biological sciences that include biochemistry, molecular genetics, cell biology, proteomics, immunology, bioinformatics and wherever the frontiers of research take the field. The emphasis is on methods from the strictly analytical to the more preparative that would include novel approaches to protein purification as well as improvements in cell and organ culture. The actual techniques are equally inclusive ranging from aptamers to zymology. The journal has been particularly active in: -Analytical techniques for biological molecules- Aptamer selection and utilization- Biosensors- Chromatography- Cloning, sequencing and mutagenesis- Electrochemical methods- Electrophoresis- Enzyme characterization methods- Immunological approaches- Mass spectrometry of proteins and nucleic acids- Metabolomics- Nano level techniques- Optical spectroscopy in all its forms. The journal is reluctant to include most drug and strictly clinical studies as there are more suitable publication platforms for these types of papers.
