Working with Olink Flex

The Olink platform was built in close collaboration with the scientific community, and the tools and services we prioritize are the ones our customers ask for. This close relationship drives proteomics forward.

With its ability to provide precise concentrations of various cytokines in both inflamed and healthy skin, Olink Flex was instrumental in distinguishing between different inflammatory skin conditions. Moreover, while using minimal volumes of skin interstitial fluid, Olink Flex has demonstrated its capability to detect cytokines such as type I Interferons, which are challenging to identify through our next-generation sequencing data.
