A biotechnology CRO built for advanced cellular fluorescence labeling, imaging, and analysis.

CellCircuit Bio is a biotechnology Contract Research Organization (CRO) specializing in advanced cellular fluorescence labeling and imaging across 2D and 3D systems. We design and adapt in vitro models to your biology, enabling more relevant and reliable data for discovery and development.

Founded by Stanford-trained scientists, CellCircuit Bio supports biopharma and biotech companies, antibody developers, and academic research teams with reproducible, high-quality imaging data across standard and complex cellular models.

We integrate optimized labeling workflows, advanced imaging, and quantitative analysis with in vitro systems, ranging from standard cultures to precisely controlled microengineered environments, to visualize and quantify protein expression, subcellular localization, and cellular signaling.

Backed by deep hands-on expertise in cellular imaging, assay development, and bioengineered systems, we also provide scientific guidance, from experimental design and marker selection to data interpretation, helping you move from experiment to decision with confidence.
