Prepare and Add Detection Antibodies

1. While the samples are incubating use Tables 9 and 10 or the

Calculation Worksheet on pages 35–36 to calculate the volume
of detection antibodies and Bio-Plex detection antibody diluent
HB needed to prepare a 1x stock. Detection antibodies should be
prepared 10 min before use.

2. Add the required volume of Bio-Plex detection antibody diluent HB to

a 5 ml polypropylene tube.

3. Vortex the 10x stock of detection antibodies for 15–20 sec at

medium speed, then perform a 30 sec spin to collect the entire
volume at the bottom of the tube.

4. Dilute detection antibodies to 1x by pipetting the required volume into

the 5 ml tube. Vortex.

Each well of the assay requires 2.5 μl of the 10x stock adjusted to a

final volume of 25 μl in detection antibody diluent HB.

5. After incubating the beads, samples, standards, blank, and controls,

slowly remove and discard the sealing tape.

6. Wash the plate three times with 100 µl wash buffer per well.
