Custom Protein Array

RayBiotech provides custom protein array development and testing services for high-throughput analysis of protein interactions and immune responses. Protein arrays consist of purified recombinant proteins immobilized on a solid support in an addressable format, enabling researchers to study antibody specificity, protein–protein interactions, small molecule binding, and immune profiling in a single experiment.

Researchers can design custom arrays containing proteins of interest or select from our existing protein array platforms depending on their experimental needs.

Applications

Custom protein arrays can be used for a wide range of research applications, including:

  • Protein–protein interaction studies
  • Small molecule–protein interaction screening
  • Antibody specificity validation
  • Antibody and autoantibody profiling
  • Receptor–ligand binding analysis
  • Inhibitor and drug candidate screening

Our Custom Protein Array Workflow

customproteinarray_workflow

Create Your Custom Array Protein List

Custom arrays can be designed using proteins from our catalog of over 50,000 purified recombinant proteins, including human, mouse, pig, and allergen targets.

Researchers may also:

  • Provide their own purified proteins for printing
  • Request new protein production through our recombinant protein services

Array Format Options

Custom protein arrays are printed on standard glass slides (25 mm × 75 mm × 1 mm). Depending on the number of proteins printed, multiple samples can be analyzed on a single slide.

Example configurations:

  • ≤ 50 proteins (printed in triplicate) → up to 16 samples per slide
  • ≤ 125 proteins (printed in triplicate) → up to 4 samples per slide
  • ≤ 300 proteins (printed in triplicate) → up to 2 samples per slide
  • > 300 proteins (printed in triplicate) → 1 sample per slide

Testing and Data Analysis Services

In addition to providing custom protein array kits, RayBiotech offers optional services to support different stages of the experiment. These include full testing services, where our team performs the entire workflow from protein production and array printing to assay execution, scanning, and data extraction.

For researchers who run the experiment themselves but do not have access to a compatible laser scanner, we also offer scanning and data extraction services. Optional biostatistical and bioinformatics analysis packages are available for projects requiring deeper data interpretation.

Additional details on these services can be found in the related services links below.
