Simplifying the Complexity of Proving Biosimilarity
Biosimilars are biological medicines that are extremely similar to already-approved biopharmaceutical drugs (originator or reference medicinal product (RMP)). Biosimilars can be manufactured when the original product’s patent expires.
A comprehensive analytical data package is the foundation of bringing a biosimilar to market. It is critical that drug developers prove there are no clinically meaningful differences between the biosimilar and its RMP in terms of the safety, purity and potency of the product.
Discover how Sartorius solutions can simplify this complex process and help bring your biosimilar to market faster.

Sartorius Biosimilar Development Solutions Offer:
Analyze multiple parameters with the same assay:
- High throughput, multiplex assay that measures ADCP via co-localization of encoding dye-labeled target cells with CD14 positive effector cells using a simplified, streamlined workflow with iQue® Advanced Flow Cytometry
- Glycan screening combined with titer measurement with Octet® BLI
- Visualization and direct quantification changes in morphology, movement and spatial orientation of cancer and immune cells over days and weeks
Conserve precious sample through multiplexing – analyze multiple parameters from the same well from low sample volume (as little as 1 microliter) with iQue® Advanced Flow Cytometry.
Lower hands-on manipulation and sample consumptions; more in-depth analysis method compared to ELISA using Octet®.
iQue® Advanced Flow Cytometry platform enables rapid, high-throughput walkaway plate sampling and automated analysis and reporting.
Incucyte® Live-Cell Analysis System automatically acquires and analyzes phase and fluorescent images of cells around the clock.

Frequently Asked Questions
It does not require cells be removed from the incubator and lifting, washing or labeling with perturbing (and expensive) antibodies is not necessary. This eliminates a wide range of potential assay artifacts and affords significant additional biological insight.
To compare the antibody-dependent (tumor) cell killing (ADCC) of trastuzumab and potential biosimilar mAbs, Incucyte® CLCA assays were assembled with co-cultures of HER2-positive SKOV-3 ovarian cancer cells and peripheral blood mononuclear cells. Link?
