Multiplex Flow Cytometry

RnAssays produces screening assays for a wide range of matrices including plasma, serum, eggs, and meat (drip) principally from pigs, poultry and bovine animals. A combination of fluorescent beads and a unique bead surface modification means that both chemical contaminants (e.g. antibiotic residues) and microbial contaminants (e.g. viral and bacterial pathogens and parasites) can be detected at the same time from the same sample.

RnAssays' bead-based multiplex technology measures various properties of a single bead, including:

  • Particle size 
  • Fluorescence of the particle to identify the type of test 
  • Fluorescence of a tag to detect the amount of the analyte.  

 

This Plex™ Technology offers the user several benefits:

  • Tests for microbiological pathogens can be combined with tests for antibiotic residues and other chemical contaminants 
  • Assay combinations are modular and flexible
  • Tens of analytes can be multiplexed simultaneously
  • Total bead surface is larger and suspended
  • The dynamic interaction of bead with analytical matrix gives better analyte-ligand contact
  • Incubation times are shorter than for ELISA tests
  • There is lower background signal compared with ELISAs
  • The assay is easier to handle.

RnAssays BV exhibits at RAFA 2011

RAVA 2011 at Prague

RnAssays attended RAFA 2011 in the beautiful city of Prague to share the news of Residue Plex™ with a global audience.

Residue Plex can identify and report the presence of multiple antibacterial residue families from one sample in one analysis run.

We spoke with interested parties from over 20 countries about the benefits of our flow cytometry affinity assays.

Particular interest was expressed in the possibility to use Residue Plex as a tool to screen out negative samples, leaving only suspected samples to be confirmed by expensive mass spectrometry.
