Our approach focuses on developing phase-appropriate bioassays for assessment of potency, efficacy and safety, giving you insight to make informed decisions during your drug development journey.

We also develop and fully document the phase appropriate analytical methods necessary to produce high-quality, well-characterized material and the rapid data needed to support successful IND and marketing applications.

For each or both services, your program will benefit from our wealth of knowledge and expertise across a diverse range of modalities including bioconjugates & ADCs, multi-specifics, fusions, fragments, agonist, and antagonist activities and more.

Extensive panel of both target and effector cells

To help understand your molecule in detail, we have an extensive panel of both target and effector cells together with a substantial in-house PBMC cell bank.

Complementing this is a broad choice of bioassay platforms, including:

  • Luminescence, fluorescence, absorbance plate-based assays
  • BiacoreTM
  • Flow cytometry
  • Incucyte® live cell imaging (and other microscopy techniques)
  • Cytokine analysis (Luminex®, FluoroSpot)

Hear what our customers have to say

“I had the pleasure of working with Abzena’s Cambridge UK team on a variety of in vitro pharmacology projects, ranging from cell-based assays to Biacore kinetic analysis. I found the team to be professional, reliable, and excellent partners. Given the virtual nature of the company I work for, we rely on strong partnerships in order to produce quality data to allow us to make strategic program decisions. The Abzena team was instrumental in providing timely, high-quality data that impacted our decision-making. I would highly recommend this team for all your preclinical pharmacology needs.”
