Recombinant Human CD19 Protein, Atto 647N Conjugate Best Seller

Detection of CD19 construct on human CART cells Human PBMC CD4+ and CD8+ T cells were either (A) transduced or (B) not transduced (negative control) with a Human CD19 CAR and then cultured for 11 days. Cells were washed twice with 2mL 1x PBS then stained with a viability dye for 15-30 min at room temp in the dark. Human block (1-001-1) was added during the viability stain to block Fc receptors. Cells were washed twice with Flow Cytometry Staining Buffer (FC001) then stained with Human CD4 PE-Cy7-conjugated Antibody and rhCD19 Atto 647N-conjugated protein (ATM9269) for 25 min at room temp in the dark. Staining was performed using our staining membrane proteins protocol.
