Discover RayBiotech's signature antibody-based proteomic platforms for multi-protein profiling. Our experts are ready to help you choose a protocol tailored to your research goals — from precise quantification to broad-coverage discovery to post-translational profiling across thousands of proteins.
RayBiotech pioneered the first commercial cytokine antibody array
Human proteins in a single discovery screen
Peer-reviewed publications using RayBiotech array platforms
Every project designed and analyzed by a PhD scientist
Both services are run in-house by PhD scientists and deliver a complete, bioinformatics-ready data package. They differ in what they measure and how broadly.
Quantitative Proteomics | Discovery Proteomics | |
|---|---|---|
Platform | Quantibody® multiplex ELISA glass-slide array (GLP-compliant) | L-Series high-density antibody array |
Quantification | Absolute concentration (pg/mL) | Semi-quantitative (normalized fluorescence intensity) |
Sample volume | 150 µL – 1.5 mL | 20 µL |
Maximum coverage | 1,200 analytes (human) | 8,000 analytes (human) |
PTM detection | — | Yes — phospho, glyco, acetyl, nitro and more |
Sample types | Serum, plasma, urine, CSF, cell & tissue lysates, culture media and more | Serum, plasma, urine, CSF, cell & tissue lysates, culture media and more |
Turnaround | 6–8 weeks | 6–8 weeks |
Species | Human, mouse, rat, porcine, bovine | Human, mouse, rat, rabbit |
Choose this if… | You need absolute protein concentration values Sample volume is not limiting (≥1 mL per sample) ELISA-grade accuracy and sensitivity are required | You want to maximize the number of proteins screened Sample volume is limited The study is exploratory — biomarker discovery, pathway screening or PTM analysis |
Five steps from first conversation to final report.
Select a service and confirm your analyte panel or array type with our team, then receive a quote.
Prepare your samples and ship them with a completed service form.
Arrays are run in our laboratory with QC at every step.
Specialized software converts raw fluorescence data into normalized, statistics-ready results.
Full data analysis delivered in Excel and PDF formats, reviewed by a PhD scientist.
Reproducible, high-quality results from our main laboratory — a high-complexity CLIA lab accredited to ISO 13485:2016 and ISO 17025:2017, operating under cGMP.
More than two decades of multiplex immunoassay experience. Every project is led by a PhD scientist with expertise in the field.
The high-density L-Series array captures post-translational modifications including phosphorylation, glycosylation, acetylation, nitrosylation, SUMOylation and more.
From targeted cytokine panels to panoramic screens of 8,000 proteins — one partner for the full range of proteomics needs.
Arrays specific for mouse, rat, porcine, bovine, rabbit and other under-served animal models.
All raw data, standard curves, normalization steps and bioinformatics-ready outputs — not just a summary report.
Researchers publish with RayBiotech platforms across discovery and validation. Three representative studies:
Using the Kiloplex Quantibody array to quantify 1,000 urine proteins across 30 patients with active lupus nephritis, investigators resolved an IFN-γ-driven chemokine gradient that flagged proliferative disease. Integrated with kidney single-cell RNA-seq, the urine signature tracked kidney-infiltrating CD8+ T cells (r² = 0.84) — positioning multiplexed urine proteomics as a noninvasive liquid biopsy.
Using the L-Series antibody array to screen ~1,000 serum proteins in acute-MI patients with and without heart failure, researchers surfaced S100A8/A9 as the top candidate — then validated it in more than 2,000 patients as a predictor outperforming troponin, BNP and hs-CRP, with Mendelian randomization supporting a causal role.
A 448-analyte Quantibody secretome screen across a living biobank of patient-derived fibroblasts identified HGF and FGF7 as the factors driving EGFR/ALK-inhibitor resistance, defining three functional fibroblast subtypes that tracked patient clinical response and immune-cell infiltration.
