Peptoid Array

High-density, glass slide-based array of peptide analogs

RayBiotech has delivered another unique solution to the search for biomarkers and small-molecule ligands: the peptoid array. The RayBio^® Peptoid Array consists of thousands of unique peptoid sequences spotted on a glass slide support. The peptoid array combines the diversity of the bead-based peptoid library with the simplicity and rapid processing of the glass chip array. In this format, 2000+ peptoids can be quickly screened for binding activity to biological targets of interest.

Peptoids are synthetic biopolymers that are analogous to peptides, except that the side chains are attached to the nitrogen rather than to the alpha-carbon. Like proteins, peptoids can fold into higher-order structures.

Peptoid sequences are selected randomly from a 10K-diversity peptoid library and spotted onto a 75 mm x 25 mm glass slide solid support. Any combination of these molecules may be printed onto a custom array. A single glass slide can accommodate up to 2800 peptoid spots in duplicate.
