In 1999, Peter J. Krauser founded PJK GmbH and started selling biochemicals and instruments for biotechnology. Its customers included mainly German universities, university hospitals, Max Planck, Helmholtz and Frauenhofer institutes as well as large pharma companies. In 2009, PJK rejuvenated and transformed itself into a company developing its own products. With the takeover of the subsidiary, Susanne Sabrowski, more and more own products and less merchandise were added to the product portfolio. PJK Biotech has been headed by Susanne Sabrowski for about 10 years now. The focus is on simple solutions for genetic research, such as reporter gene assays. The know-how of the company covers the field of luminescence, fluorescence and absorption measurement with their application products such as cell based assays, ELISA and Western Blot. Today, PJK Biotech's customers are scattered all over the world.
