In-situ capture of T-cells and analysis of membrane receptor affinity with biofunctionalized lipid sensor
Application Note #167
Schematic view of TCRs on whole CD8+ T-cells binding to pMHCs.
Assessment of T-cell specificity to tumor associated antigens is crucial for the development of personalized immunotherapies against cancer. Multi-Parametric Surface Plasmon Resonance (MP-SPR) was applied for characterization of interaction of T-cell receptors (TCR) from tumor-specific CD8+ T-cells. Intact live cells were captured onto biomimetic surfaces composed of artificial cell membranes functionalized with peptide-major histocompatibility complexes (pMHC). Real-time affinity analysis of immunological synapse formation between TCR and pMHC was completed from 4 different T-cell populations.
