In vitro:

  • Primary immune assays using isolated T cells or other immune subsets:
  • Proliferation assays
  • Cell surface marker profiling
  • Intracellular cytokine staining by flow cytometry, or cytokine measurements from cultured T cell supernatant by ELISA or Luminex
  • MLR
  • Antigen-recall assays
  • Others

In vivo: Syngeneic models (for small molecules, cross-reactive or surrogate antibody development):

  • More than 20 syngeneic tumor models including some of the most widely used models, such as CT26, MC-38, 4T1, B16F10, RENCA, EMT6, LLC, A20 and more.
  • Orthotopic and metastasis models

Humanized mouse models:

  • Adoptive transfer of human PBMC into immune compromised animals (under optimization)
  • Human target knock-in: PD-1, CTLA-4, and more to come

Ex vivo analyses:
