Molecular Biology

Our molecular biological department – as a biosafety level 2 laboratory – offers a variety of up-to-date analytical methods.

Our motivated team will be pleased to support you in method development and method optimisation, validation/verification of methods in accordance with pharmacopoeias and ICH guidelines as well as in product-specific suitability tests of the test method and consult you on questions relating to your products or projects.
