A novel polyclonal antibody library for expression profiling of poorly characterized, membrane and secreted human proteins

► A novel library of 1559 polyclonal antibodies for membrane/secreted human proteins ► The proteins targeted by the antibodies are unknown or marginally characterized ► The library was validated by WB, confocal microscopy, immunohistochemistry ► A subset of antibodies was used to profile expression of target proteins in tumors ► The antibody library is a tool for systematic protein expression profile analysis
