Identify protein-protein interactions in as little as a day

ProtoArray® Human Protein Microarrays are an excellent method to identify protein interactions. Using this method you can profile your purified protein against 9,000 functional proteins and identify possible binding partners. Since the identity of every feature on the array is known, you can immediately identify any target. The protocol is straightforward and is compatible with both native and modified proteins, with antibody and biotin-streptavidin detection protocols available.

The breadth of content offered by ProtoArray® microarray makes it an ideal proteomics platform for discovery researchers who are attempting to uncover new connections that may be difficult to identify using other technologies. Researchers studying a variety of proteins have demonstrated validation of protein profiling results on the ProtoArray® protein array with other in vivo and in vitro assays [1–3].

The ProtoArray® Protein-Protein Interaction Profiling application is available either as a custom service or as a product.
