Discovery Proteomics Services
Efficiently identify key proteins of interest and post-translational modifications (PTMs) when you maximize your protein expression discovery efforts with RayBiotech’s Discovery Proteomics Services.
We use our semi-quantitative, high-density arrays for this service, and work with you to determine whether our label-based or sandwich-based technologies will best achieve your project goals.
Regardless of which technology you choose, we’ll maximize the number of proteins that are simultaneously assessed. We can use any of our antibody array products to quickly screen for biomarkers, PTMs, and other targets across 8000 human, 2808 mouse, 1500 rat, 50 porcine, 30 bovine, or 500 rabbit proteins, or we can create a custom array to meet your project needs.

Why L-Series?
The broadest antibody-based screen available, from a fraction of the sample other high-plex platforms need.
8,000
Human proteins in a single screen
20 µL
Of serum or plasma, vs. 40 µL for PEA and 130 µL for aptamer arrays
300+
Peer-reviewed publications using L-Series arrays
4 species
Human, mouse, rat and rabbit, plus custom arrays
When to Choose Our Discovery Proteomics Services
We recommend choosing this service when you want to screen up to 8,000 proteins, have limited sample (as little as 20 µL), or are running an exploratory study of biomarkers, pathways or PTMs, and semi-quantitative results are sufficient.
If you need absolute concentrations (pg/mL) with ELISA-grade accuracy, you may prefer our Quantitative Proteomics Services. Compare both services →
Why You Should Choose Our Discovery Proteomics Services
For Our Patented Array Technologies and Proven Workflows
This service is delivered using off-the-shelf or custom RayBiotech Label-Based Arrays (L-Series) or Glass Slide Antibody Arrays (G-Series).
Label-Based Arrays maximize the number of targets and PTMs like acetylation, palmitoylation, nitrosylation, oxidation, glycosylation, or phosphorylation you can assess. This approach relies on direct labeling of sample proteins with biotin, enabling detection through binding with labeled streptavidin and avoiding the need to develop validated antibody pairs. Learn more about the PTM analyses available.
Pathway Profiling Arrays target a specific signaling pathway, process or disease mechanism with the same L-Series technology, ideal for mechanism-of-action and pathway-focused studies.
Glass Slide Antibody Arrays use the familiar sandwich detection format and our validated antibody pairs. This option requires larger sample volumes than the L-Series.
For Our Years of Experience
Founded in 2001 as the first company to commercialize the antibody array, we continue to use our decades of experience in multiplex, high-throughput protein analysis to deliver outstanding proteomics services to the research community.
