Evaluation of CD19sIg1-4 fusion protein for detection of anti-CD19 CAR-modified primary human T-cells. Flow cytometry plots demonstrating the sensitivity of detection of anti-CD19 CAR-transduced human primary T-cells mixed in increasing numbers of non-transduced (NT) T-cells using FITC-conjugated anti-IgG Fc F(ab’)2 fragment (FITC-anti-IgG Fc, upper panels) or Alexa Fluor 488-labeled CD19sIg1-4 (AF488-CD19sIg1-4, lower panels).
