3. Prepare Wash Method
Bio-Plex Pro assays are compatible with both magnetic separation and
vacuum filtration methods. However, for best results, we recommend
performing the assays in a flat bottom plate with magnetic separation.
Setting up the Bio-Plex Pro or Bio-Plex Pro II
Wash Station
The wash station does not require calibration; however, it should be primed
before use. For more information, refer to the Bio-Plex Pro and Pro II wash
station quick guide (bulletin #5826).
1. Install the appropriate plate carrier on the wash station.
2. Use the Prime procedure to prime channel 1 with wash buffer.
Setting up the Bio-Plex Handheld Magnetic Washer
Place an empty flat bottom plate on the magnetic washer by sliding it
under the retaining clips. Push the clips inward to secure the plate. Make
sure the plate is held securely. If needed, the clips can be adjusted for
height and tension. For detailed instructions, refer to the user guide
(bulletin #10023087).
Setting up a Vacuum Manifold
Calibrate the vacuum manifold by placing a standard 96-well flat bottom
plate on the unit and adjusting the pressure to –1 to –3" Hg. In general,
100 µl liquid should take 3–4 sec to clear the well. For more detailed
instructions, refer to bulletin #10005042.
