Discovery Proteomics Services
Efficiently identify key proteins of interest 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 and other targets across 8000 human, 1308 mouse, 1500 rat, 50 porcine, 30 bovine, or 500 rabbit proteins, or we can create a custom array to meet your project needs.
Full testing service is now 50% off through June 30th using code 2023HD50. Send us your samples. We'll Send You Results. Contact us for a quote: [email protected]
When to Choose Our Discovery Proteomics Services
We recommend choosing this service when you need to maximize the number of proteins that are analyzed, sample volume is not limiting, and semi-quantitative results are sufficient.
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 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.

Frequently Asked Questions
Still have questions?
Most of our arrays are compatible with any biological fluid. This includes cell culture media, cell lysates, tissue lysates, and all clarified body fluids (serum, plasma, urine, cerebrospinal fluid, BAL, saliva, tears, etc.)
However,the label-based arrays (L-Series), have limited compatibility with lysates and non-serum/plasma body fluids. Our phosphorylation arrays, which detect membrane-bound receptors, are only validated for use with cell and tissue lysates.
In general, any cell-free extract that contains soluble, non-denatured proteins is likely to work with our arrays.
There are a few differences between the glass-slide and membrane-based arrays. The main difference concernsdetection methodology. Our glass-slide based arrays use fluorescence and need a compatible laser scanner. However, our membrane-based arrays use chemiluminescence that is detectable with most western blot imaging systems.
The sample size needed for the glass-slide based is smaller than the membrane-based. Glass-slides require ~70 ul – 100 ul, while the membranes require at least 1 ml, after dilution.
Lastly, the price for the glass-slide based arrays are generally cheaper.
The positive control spots are standardized amounts of biotinylated IgG. They are used for signal normalization, monitoring of the detection step, and to help orient the array image.
The negative control spots are printed with buffer only, and are not expected to give signals. Negative control spots are used for background subtraction.
The areas on the array map labeled as “blank” are empty (there is nothing printed there). Both the negative control and blank spots should give similar intensity values. Either one may be used to represent the background.
