As part of our proteomic studies and research collaborations, we have generated and thoroughly characterized a number of antibodies against membrane proteins and associated partners. A selected set – mostly affinity-purified polyclonal antibodies – will soon become commercially available by the end of 2008. Our antibodies are unique with respect to their quality and level of validation: specified applications like Westernblots, immunohistochemistry and affinity purification have been tested using native source-derived sample specimens, stringent controls including knockout samples or independent antibodies and quantitative mass spectrometry.
