Cell-Based Assays and Imaging

Cell-based assays in both 2D and 3D formats across a broad range of human primary cell types
Our assays have provided data supporting a range of different therapeutic indications from diabetes to fibrosis and oncology, but our primary focus remains in anti-inflammatory and autoimmune research. Our customized approach develops fit-for-purpose assays to the specific needs of your program. In addition to assay development, our breadth of analytical platforms enables us to deliver a comprehensive range of assay endpoints, including mediator/cytokine release, changes in gene expression, ICC, and high content cellular imaging.

Cell-Based assays customized to your program

Example Cell Types Used for Assay Development


  • Blood cells: PBMCs, monocytes, lymphocytes, neutrophils, monocyte-derived macrophages
  • Skin cells:  keratinocytes, fibroblasts
  • Lung cells: bronchial epithelial cells, alveolar macrophages, alveolar type II cells, smooth muscle cells, tumor epithelial cells, cancer-associated fibroblasts
  • Liver cells: hepatocytes, Kupffer cells, stellate cells
