CD22 Protein (C-His, Human)

Flow cytometric analysis of anti-CD22 CAR expression. 5e5 of anti-CD22 CAR-293 cells were stained with 100 μL of 1:50 (2 μL stock solution in 100 μL FACS buffer) of PE-conjugated human CD22 Protein (Site-Specific PE Conjugation, His Tag, Cat. No. 11958-H86H-SP) and negative control protein. Non-transduced 293 cells were used as a control (left) . PE signal was used to evaluate the binding activity (QC tested) .
