A modified bead having a structure represented by the formula B-X-A is disclosed, wherein B is a solid support preferably in the form of a bead, X is a spacer selected from the group consisting of poly(threonine), poly(serine), dextran, and poly(ethylene glycol), and A is an antibody. Using such modified beads in an immunoflow module, antigens can be captured and detected from food and environmental samples in about 30 minutes. |
