Nanobodies
Nanobody characterization
In the recent years, the interest and application of nanobodies or single-domain antibodies has grown significantly. Their unique chemical properties have made them promising candidates for a whole new kind of delivery systems and therapeutic methods.
Biofidus provides a broad range of state-of-the-art analytical techniques to support your biologics. We cover the structural as well as the functional characterization of proteins allowing us to provide you with a complete analytical package for your analytical challenge.
Besides an in-depth analysis of the protein primary structure, amino acid modifications, charge and size heterogeneity, we are experts in analyzing the functional properties of your lead molecules via customized cell-based assays and surface plasmon resonance (SPR) analysis.
Our vast experience and deep knowledge in this field allows us to guide you through the variety of available methods and help you find the optimal analytical solution for your project.
In accordance with your needs, we adapt and, if required, qualify (according to ICH guidelines) our platform methods tailored to your drug substance (DS), its individual formulation matrix and your distinct analytical question.
Get in contact with us to quickly find the optimal setup for your analytical challenge and to speak directly from expert to expert.
