Biomarker Testing Services
RayBiotech offers a comprehensive suite of laboratory biomarker testing services in a wide range of therapeutic areas. With our expertise, we work with clients to provide a unique approach to each project and optimal strategies from design to completion.
Our lab can help clients to:
- Identify biomarkers
- Design experiments
- Choose the best analytical methodology
- Develop and validate the specific assay(s)
Our capabilities include advanced technologies and specialized expertise in the below areas.
Bead-Based Arrays
RayBiotech’s multiplex bead array is an advanced technology using antibody-conjugated multiplex beads to quantitatively detect a wide range of analytes with high sensitivity in a liquid phase.
- A variety of sample types can be used including whole blood, PBMCs and other primary and immortalized cell lines.
- Capability for up to 12-color or 18-color analysis depending upon the needs of the assay.
- Multiplexing for up to 50 targets proteins.
- Custom and pre-validated panels are available.
- Minimal sample volume required per test.
Quantibody
Quantibody® glass slide arrays are fully quantifiable multiplex immunoassays.
- Contains fully validated assays for cytokines, chemokines, growth factors, soluble receptors, and many more molecule classes.
- Design and validation of customized biomarker panels available for >1200 human, >640 mouse, and other species: Rat, Sheep, Chicken, Cow, Pig, Horse, Dog, Primate, Rabbit, Cat & Dolphin.
- Up to 40 proteins can be measured with just 50 µL of sample.
ELISA
Choose from over 4000 targets across 16 different species and 6 different ELISA platforms for single target biomarker detection.
- Sandwich ELISA
- Phosphorylation ELISA
- High-Sensitivity Immuno-PCR
- Competition-based ELISA
- Cell-based ELISA
- Transcription Factor Activity Assay
Auto-Western
RayBiotech’s Auto-Western Service marries our state-of-the-art capillary immunoprobing system with our vast pre-validated antibody library.
Our high throughput system can achieve ng to pg sensitivity with only 5 µL of starting material.
- Standard curve may be included for full quantification.
SIMOA
Single molecule array (Simoa™) testing is a powerful new technique that utilizes the isolation of individual immuno-complexes on paramagnetic beads to generate data that is orders of magnitude more sensitive than standard sandwich based immunoassay techniques.
- Choose from a library of over 4,000 targets
- Sensitivity as low as femtogram (fg/ml) levels
The RayBio Ultrasensitive Simoa Testing Services reach femtogram (fg/ml) levels, allowing the detection and quantification of biomarkers at concentrations previously difficult or impossible to measure.
