Protein Arrays

Efficiently explore protein-protein and protein-ligand interactions—such as for receptor discovery or to screen for auto-antibodies related to cancer or autoimmune disease—with convenient pre-printed or custom protein arrays from RayBiotech.

Why Choose RayBiotech Protein Arrays?

Each protein array we offer is manufactured to our exacting standards on-site in our facilities (Georgia, USA). Our processes and quality standards have been developed over decades and, as the company that pioneered the protein microarray, is based on more experience developing and manufacturing this technology than any other company.

In addition, all of our products and services are backed by a team of expert scientists, all with PhDs in the life sciences, who are ready to help with your scientific, experimental, and logistical questions.

Protein Arrays Versus Antibody Arrays—Which Should I Choose?

If you use the term "protein array" (or protein microarray) interchangeably with "antibody array," you’re not alone. However, it’s important to note that these are different types of arrays that are used in different applications.

Protein arrays consist of immobilized recombinant proteins arrayed on a solid support, such as a membrane or glass slide. They are used to profile serological antibodies as well as to study protein interactions with other proteins, peptides, DNA, and drugs.

Antibody arrays, on the other hand, consist of immobilized antibodies arrayed on a solid support and are used for protein expression profiling.
