Instruction Manual

7. Run Assay
The following instructions apply to premixed multiplex, singleplex, x-Plex
™
,
and Express assay formats.
Considerations
n
Bring all assay components and samples to room temperature before use
n
Use calibrated pipets and pipet carefully, avoiding bubbles
n
Pay close attention to vortexing, shaking, and incubation instructions.
Deviation from the protocol may result in low assay signal and
assay variability
n
Assay incubations are carried out in the dark. Cover the plate with
aluminum foil or otherwise protect from extended exposure to light
Table 8. Summary of wash steps and incubations. After each assay step, select the
appropriate Bio-Plex Pro
™
wash station program or perform the appropriate manual wash step
as summarized below.
Using a Vacuum Manifold
n
After each incubation, place the filter plate on a calibrated vacuum
apparatus and remove the liquid by vacuum filtration
n
To wash, add 100 μl wash buffer to each well and remove the liquid as
before. Ensure that all wells are exposed to the vacuum
n
Thoroughly blot the bottom of the filter plate with a clean paper towel
between each vacuum step to prevent cross contamination
