Determination of MagaCell-IgY beads volume required for immunocapture of MAP ATCC 19698 spiked in bovine feces (2 × 104 cells/g) and incubated at RT for 15 min. For each MagaCell-IgY beads volume used, DNA was run undiluted (N) and at dilutions of 1:10 (−1) and 1:100 (−2). The bead volumes were as follows: lanes 1 to 3, 5 μL; lanes 4 to 6, 10 μL; lanes 7 to 9, 15 μL; lanes 10 to 12, 20 μL. Lane M — 1-kb molecular weight marker; lane +C — positive-control DNA (ATCC 19698); lane −C — negative water control.
