give
a strong positive PCR signal showing that the functionalized
magnetic beads were able to captureC. jejunibacteria. Similar
results were observed with mAb2- and pAb-coated beads (data not
shown). As a whole, these results demonstrate that the antibodies
were conjugated to the magnetic beads and that their immunological activities were still functional after the coating process. The
results also indicate that at least 5 times of washing are required to
remove all non-bidding bacteria
