6. Reconstitute the vial of standards in 781 µl of a diluent similar to your final
sample type or matrix. Reconstitute the vial of quality controls in 250 µl of
the same diluent, as shown below. Vortex for 5 sec and incubate all vials
at once on ice for 30 min.
7. Prepare a fourfold standard dilution series and blank as shown below.
Vortex for 5 sec between liquid transfers.
Note: The quality controls are ready to use after reconstitution. No
dilution is needed.
8. After thawing samples, prepare according to the guidelines shown below.
9. Vortex coupled beads for 30 sec and dilute to 1x in Bio-Plex assay buffer
as shown below. Protect from light.
