RP1 (PMT) Setting for Standard Curves
The Bio-Plex 200 and 3D systems have two RP1 (PMT or photomultiplier
tube) setting options, while the Bio-Plex

®

MAGPIX

has no PMT and

therefore no PMT setting options. Instead, MAGPIX uses default instrument
settings similar to low PMT on the Bio-Plex 200 (Table 6).

Table 6. Overview of PMT setting options on Bio-Plex systems.

The Bio-Plex Pro

human and mouse cytokine assays were developed

on the low PMT setting using the Bio-Plex 200 system, while the rat
cytokine assays were developed on the high PMT setting. Protocols using
alternative standard dilution series or different PMT settings should be
validated by the end user, for example when mixing the cytokine assays
with diabetes assays (Table 7 and Table 24).

settings and cross-panel multiplexing compatibility.

Reconstitute a Single Vial of Standards

This procedure prepares enough material to run each dilution in duplicate.

1. Gently tap the vial containing the lyophilized standard.
