At RoukenBio, our multidisciplinary team of experts is dedicated to supporting the development of therapeutic antibodies for the treatment of diseases, each with its own unique challenges and opportunities. Our deep expertise across different therapeutic areas, combined with our state-of-the-art assay platforms and custom development capabilities, makes us the perfect partner for your drug development journey.

Whether you are advancing therapeutic antibodies, engineered cell therapies, or small-molecule immunomodulators, our scientists build the bespoke in vitro models needed to reveal mechanism, potency, safety, and functional biology. With cross-functional expertise in immunology, bioassay development, and cell engineering we design the right assay system for your modality to drive your project forward reaching the clinic faster.


We use engineered and primary human immune cells to characterize binding, signaling, effector function, receptor engagement, cytokine modulation and other immunological mechanisms. Helping you select and differentiate candidates, understand mechanism of action, and generate data to support IND-enabling packages.


For developers of adoptive cell therapies, RoukenBio builds customized in vitro models using both donor-derived immune cells and bespoke engineered cell systems. We assess cell potency, activation, cytotoxicity and immunological safety, giving you human-relevant insight into how your cell therapy behaves in controlled immune environments.


At RoukenBio, we evaluate small-molecule modulators of immune pathways using in vitro cellular assays. We quantify pathway inhibition/activation, downstream signaling, cytokine release profiles, and immune-cell function to help identify the most promising candidates.
As a global pharmaceutical contract research organization, RoukenBio provides drug development services to the vast scientific network worldwide. Our scientific partners are based mainly in the USA—particularly in Massachusetts (Boston, Cambridge) and California (San Francisco and San Diego)—Canada (from Vancouver up to Seattle), the UK, and Europe.
Difficulty doesn’t deter us; it inspires us. Give us a problem, and we’ll find your solution. Our versatile specialists embrace every obstacle as an opportunity to showcase our innovative thinking and problem-solving prowess.
