How it works

Bead-based sandwich immunoassay

GeniePlex uses bead populations distinguished by size and fluorescence intensity, each conjugated with a specific capture antibody that traps its target analyte (e.g. a cytokine) from the sample.

Captured analyte is detected with a biotinylated detection antibody against a second epitope, followed by Streptavidin-R-phycoerythrin. A flow cytometer reads each bead’s identity and its PE signal, and concentrations are read off a standard curve — measuring up to 24 analytes in a single reaction.

Workflow

Three short incubations, one read

The complete GeniePlex protocol runs in about 4 hours.

1

Capture (60 min)

Incubate sample with capture-antibody-conjugated beads, then wash.

2

Detect (30 min)

Add biotinylated detection antibody, then wash.

3

Read (20 min)

Add Streptavidin-PE, wash, resuspend and acquire on a flow cytometer.

Multiplex vs. ELISA

Why multiplex?

Measuring many analytes at once means less sample, fewer plates, less time — with sensitivity that matches or beats singleplex ELISA, and excellent correlation with Luminex® xMAP technology.
