How will High-Plex proteomics take your research to the next level?


Traditional targeted protein analysis approaches like multiplex assays are valuable for enhancing our understanding of specific pathways and biomarker behavior but lack potential for proteome-wide discoveries and screening.


High-plex analysis leaves behind the limitations of traditional approaches. Incorporate High-plex analysis into your research methodology to unlock novel biological insights.

What is High-Plex Protein Analysis?

High-Plex Protein Analysis refers to the simultaneous analysis of 100s to 1000s of proteins providing a comprehensive view of the protein landscape.

The emergence of oligonucleotide-labeling of antibodies has enabled NGS technologies to be used in protein research and led to new levels of multiplexing.

The new High-Plex Protein technologies based on NGS have allowed unprecedented quality, speed, sensitivity, specificity, and proteome coverage.

You can now discover important biological mechanisms and focus on novel biological insights.
