STEFFENS BIOTECHNISCHE ANALYSEN GmbH is dedicated to the development and production of enzyme-linked immuno sorbent assay (ELISA) test kits. Some of these kits are manufactured exclusively for individual customers; others are generally available and distributed directly by our company. Most of the tests measure human diagnostic parameters and are manufactured in compliance with the European in vitro diagnostica (IVD) directive 98/79/EC.



Our in vitro diagnostic test kits for detection of autoimmune diseases and Helicobacter pylori infections have the CE mark and offer reliably excellent quality with high ease of use.



Our outstanding streptavidin coated microplates offer strong binding with a very low background signal for your application with any biotinylated molecule, especially those that cannot be bound by passive adsorption.
