OmicsArray™ Peptide Microarray Services

Pre-made peptide arrays

Pre-made Peptide Array Services

Validated content for Infectious Disease, Autoimmune, and Oncology research.

We offer a wide range of pre-designed peptide libraries covering major proteomes and disease markers. These arrays feature content rigorously curated from the Immune Epitope Database (IEDB) and other leading sources, allowing for immediate screening of specific biological questions without the need for custom design.

Key Categories:

Infectious Diseases: Full proteomes of SARS-CoV-2, Dengue, Zika, and broad pathogen epitope screens.
Autoimmune & Allergy: Comprehensive profiling of autoantigens (SLE, RA, MS) and common allergens.
Oncology: Tumor-associated antigens (TAAs), melanoma markers, and oncoviruses.
Gene Therapy Safety: CRISPR/Cas9 immunogenicity and AAV capsid profiling.

Custom services

Custom Peptide Array Service

Tailored profiling projects designed for your specific research targets

Our custom service allows you to translate any protein sequence or peptide list into a high-density array experiment. Because we print directly on the slide, we can create highly overlapping libraries (e.g., shift of 1 amino acid) to pinpoint exact binding residues with unmatched precision.

Technology

Step 1: PRINT

In less than a minute, PEPperPRINT’s patented 24-color laser-printer prints a layer of up to 300,000 defined spot patterns of pre-activated and Fmoc protected amino acid toner particles onto a specially coated glass slide.
Step 2: MELT & COUPLE

A heating step melts amino acid toners between printing cycles, releasing activated amino acids to initiate a coupling reaction to either the chip surface, or to previous residues.
Steps 3-4: WASH & DEPROTECT

After removal of excess material by washing, and de-protection of the N-terminal Fmoc group by cleavage, the next amino acid layer is printed and coupled. The cycle is repeated until the designated linear peptide is synthesized e.g. for linear epitope mapping.
Step 5: CYCLIZE

Optimized cyclization routines allows disulfide- and thioether bridging between N and C terminus of each peptides enabaling peptide loops for e.g. conformational epitope mapping.

FAQ

Q: What samples do I need to send?

A: We typically require ~20 µL of serum or plasma, or ~20 µg of purified antibody for a standard assay.

Q: What is the turnaround time for the service?

A: Turnaround times vary by project complexity. Standard pre-designed panels generally have a faster turnaround than fully custom designs.

Q: What data will I receive?

A: You will receive a complete data package including the raw TIFF images, a quantified data file (Excel) with signal intensities for every peptide, and a summary report featuring heat map visualizations and epitope alignments.
