Research & Development

Employees and decision-makers from Research & Development in particular have direct access to our inventory of over 500,000 patient samples.

We collect the samples directly from our donation centers in Heidelberg and Munich or source samples from our long-term collaborations with our network of laboratories. Another focus is the acquisition of samples from Africa, which we either sample in our own donation center in Cameroon or through our partners / study centers.

You can also purchase prospectively collected negatively tested samples or matched sets from us - with over 300 active donors, we can cater for almost every wish. The sampling of negative donors also takes place daily in our plasma center in Heidelberg.
