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 5).

The Bio-Plex Pro TGF-b assays were developed on the low PMT setting
using the Bio-Plex 200 system. Protocols using alternative standard
dilution series or PMT settings should be validated by the end user.
