When looking alike isn’t enough.
For biosimilar insulin, demonstrating structural similarity is only the beginning.
Insulin biology involves multiple receptor interactions, signaling pathways and biological responses. That’s why functional characterization requires more than a single potency assay.
In our new blog, Justyna Sładowska explores how orthogonal functional assays can build a more complete picture of insulin biosimilarity, from:
• receptor binding and selectivity
• receptor activation and intracellular signaling
• metabolic activity and potency
• safety-relevant responses and product quality
Together, these approaches help connect molecular similarity with biological function and provide the evidence needed to support a robust biosimilarity assessment.
