Video 3. Simultaneous observation of ZAP70-EGFP recruitment and pMHC:TCR binding immediately after a living AND T cell lands on the SLB.
This video shows binding of pMHC:TCR, and is from the same cell as the ZAP70-EGFP data in Video 2. Agonist pMHC is labeled as MCC-Atto647N. These data were analyzed to create the spatial map of pMHC and ZAP70 positions displayed in Figure 4A.
