Videos! SPR applications in protein characterization

By Christina Burtsoff Asp

See how fellow Biacore users are improving protein characterization with surface plasmon resonance (SPR).


Watch these exclusive videos from the Biacore Analytical, Comparability and QC Symposium, Vienna, Nov 2017, industry luminaries share insights, tips and techniques that illuminate how SPR with Biacore system is helping advance biotherapeutics research and production.

Start off with a deep dive into a range of assays using Biacore systems to evaluate potency. Followed by Fredrik Sundberg’s insights into global industry and regulatory trends.

Mike Wilcox on compliant Fc receptor potency validation

An important step in the development of mAb biosimilars is to compare binding to Fc receptors of the new therapeutic to the reference medicine. To do this, in vitro functional testing methods are paramount, as outlined by guidelines presented in the 2005 report by the European Medical Agency.

Watch this video where Eurofins Biopharma shares how to perform an SPR assay to validate Fc receptor potency according to ICH Q2 R1 and FDA guidelines.

Stuart Knowling explores SPR in relative potency assays

All biological products must meet prescribed safety, purity and potency requirements for BLA approval. Potency is considered a critical quality attribute (CQA) for any biological product, and the implementation of relevant assays is often at the center of many challenges and discussions among developers and regulators throughout product development.

Watch this video to get a taste of how SPR binding and affinity are being used in relative potency assays, and how that correlates with antibody-dependent cell-mediated cytotoxicity (ADCC) in work being conducted at Sartorius Stedim BioOutsource.

Veronica Fridh sheds light on SPR surrogate potency assays

The utilization of SPR in process optimization and quality control is increasing, due to the combination of robustness, high sensitivity, precision, and accuracy that Biacore SPR technology provides. This, coupled with high throughput capabilities and decreased sample preparation requirements, is why SPR is an attractive method relative to traditional analytical techniques that measure protein quantity and quality.

Watch this video on how SPR surrogate potency assays facilitate comparability biosimilar studies.
