Anti-keratin Monoclonal Antibodies for Identifying Animal Hair Fibers

In a study from May 1, 2004, researchers developed monoclonal antibodies to differentiate between cashmere and wool fibers. They immunized mice with keratins from cashmere and produced antibodies that showed distinct immunoreactivity with keratins from cashmere and wool, suggesting species-specific identification potential. Two clones, P21 and L45, were highlighted for their specific reactions. This method could offer a more objective and precise alternative to traditional microscopic identification techniques in the textile industry. The study, conducted by the Institute for the Study of Macromolecules of the Italian National Research Council and funded by the Cashmere and Camel Hair Manufacturers Institute, indicated that these antibodies could be used for quantitative analysis of fiber blends and could lead to new routine characterization techniques for animal hairs.
