MPR is a repository of information on commercially available phospho-specific antibodies to human phosphorylation sites.

MPR provides a BLAST search for phosphorylation sites using as query the amino acid sequence surrounding the site.

MPR provides direct links to the relevant antibodies from many companies including BD Pharmingen, Biosource International, Cell Signaling Technology (CST), Santa Cruz Biotechnologies, Upstate Biotechnology.

While every attempt is made to make MPR accessible and viewable on any device, MPR is best viewed in 1024×768 resolution (or higher).
