Maximizing Capture Efficiency and Specificity of Magnetic ...
· In order to introduce specificity for Mycobacterium avium subsp. paratuberculosis prior to a phage amplifiion assay, various magneticseparation approaches, involving either antibodies or peptides, were evaluated in terms of the efficiency of capture (expressed as a percentage) of M. avium subsp. paratuberculosis cells and the percentage of nonspecific binding by other Mycobacterium spp. .
