Storage & Solubility Information
| Bioactivity | 1. Flow cytometric analysis of anti-CD19 CAR expression. 293 cells were lentivirally transduced with anti-CD19 CAR. Flow cytometric analysis was performed with a negative control protein and CD19 Protein, Human, Recombinant (His), APC-Labeled (Cat#TMPY-07081), respectively. Non-transduced 293 cells were used as a control (left). 2. Binding activity of APC-conjugated CD19 protein to PBMC cells. PBMC cells were stained with anti-CD3 antibody and CD19 Protein, Human, Recombinant (His), APC-Labeled (Cat#TMPY-07081) and detected by flow cytometry. PBMC cells stained with anti-CD3 antibody were used as a control (left). |
