Biosimilar Development

The development of biosimilars is growing extremely rapidly with an annual growth rate of ca. 30% . At the heart of this growth in development is a comprehensive analytical data package to demonstrate that there are no clinically meaningful differences between the biosimilar product and the originator product in terms of safety, purity, and potency. Discover how we can help you to streamline this complex process.

iQue3®️ Advanced Flow Cytometry Platform

Meet the iQue3 - the most advanced flow cytometry platform with a focus on speed - from setup, to acquisition, and analysis - to get you from samples to actionable results in record time. The iQue3 combines a patented sampling method which allows for the fastest sample acquisition in the industry. It has the ability to handle 96, 384, or 1536 well plates, and enables continuous plate loading through connection with any automation system.

Discover the fastest path to actionable results with the iQue platform:

  • Multiplexed binding assays (96-well plate in 5 min)
  • Identify targets in their native conformation
  • Evaluate specificity and species cross-reactivity in the same well
  • Get information on cell health, isotype and titer from a single assay

Microsart® AMP Mycoplasma Kit

Mycoplasma are widespread contaminants in cell culture. Given their tiny size (~0.3-0.8 µm), mycoplasma cannot be visualized by microscopy. Cultivation-based detection takes 28 days, and even then, the colonies are difficult to visualize with the naked eye. Mycoplasma-contaminated products present a human health risk, so you must confirm your cell lines are uncontaminated.
Microsart® qPCR kits offer a safe and rapid method for early detection of mycoplasma contamination. It’s fast, highly specific and compliant with international guidelines.
