PEPperPRINT’s high tech printing instrument is conceptually based on a 4-color laser printer, but the peptide laser accommodates 24 amino acid printing units for the 20 main L-amino acids as well as other monomers like D-amino acids and citrulline. Combining laser technology with image recognition optics for glass side alignment, linear stage and precision mechanics for repeat printing with micron resolutions, PEPperPRINT can precision print up to 275,000 spots per minute for HTP applications.
Based on PEPperPRINT’s printing platform, we offer PEPperCHIP® Custom Peptide Microarrays, PEPperMAP® Custom Services and Ready-To-Go PEPperCHIP® Standard Peptide Microarrays.
PEPperCHIP® Standard Peptide Microarrays cover selected epitopes, antigens or whole viral proteomes translated into overlapping peptides, or random peptide libraries for signature discovery. The PEPperCHIP Standard Arrays are ready to use, all you need is your sample, Incubation Tray, Staining Kit, Microarray reader, and PepSlide Analyzer software (free trial available).

Type 1 Epitope Mapping Service: Epitope Mapping of one antibody or serum sample against a single antigen translated into 15 aa peptides with a peptide-peptide overlap of 14 aa
Type 1 Epitope Mapping of a monoclonal antibody against an antigen translated into 15 aa peptides with 14 aa peptide overlap. The microarray scan (left) as well as the intensity plot (right) reveal a stretch of adjacent peptides with a consensus motif that represents the epitope of the antibody. Stained HA (red) and Flag (green) control peptides frame the antigen-derived peptides.
Type 2 Epitope Mapping Service: Epitope Mapping of one antibody or serum sample against a single antigen translated into 10, 12 and 15 aa peptides with a peptide-peptide overlap of 9, 11 and 14 aa.
Type 2 Epitope Mapping of a polyclonal antibody against an antigen translated into 10, 12 and 15 aa peptides with 9, 11 and 14 aa peptide overlap. The microarray scan (left) as well as the intensity plot (right) of the 15 aa peptides shows an apparent single epitope stretch which can be separated in two adjacent epitopes with the 10 and 12 aa peptides. Stained HA (red) and Flag (green) control peptides frame the antigen-derived peptides.
Peptide Substitution Scans: Full permutation scan (exchange of each amino acid with all other L-amino acids) of a known epitope against one antibody or serum sample
The full substitution scan of epitope GVPEQEDSVLFR with 23 different amino acids was printed in single spots with two array copies next two each other. HA and Flag control peptides framing the peptide array were stained with the corresponding control antibodies at high and homogeneous spot intensities
Antigen and Epitope Discovery Microarrays: PEPperCHIP Discovery Microarrays are based on a discovery format that covers 50,000 different peptides (up to 60,000 peptides, e.g. 30,000 different peptides in duplicate) for high throughput screening. Discovery Microarrays are ideal for large-scale antigen and epitope discovery screens for biomarker identification, multiplex epitope mappings or peptide discovery and high throughput optimization.
334 different proteins of interest were translated into 15 aa peptides with a peptide-peptide overlap of 10 aa resulting in 26,463 different peptides in duplicates. The first assay was based on pooled control sera at a dilution of 1:1000 followed by data read-out and quantification (left top). A second assay was performed with pooled patient sera at the same dilution (right top) that revealed a number of antigens and epitopes that were exclusively stained by the pooled patient sera. Antigens and epitopes with the highest differential response were selected (right bottom) for further investigations with increased serum numbers on PEPperCHIP® Peptide Microarrays with standard dimensions. Staining of HA (red) and FLAG (green) control peptides complement a typical Antigen and Epitope Discovery Screen (left bottom).
