Fig1:
Western blot analysis of CD19 on different lysates with Rabbit anti-CD19 antibody (HA723533) at 1/50,000 dilution. Lane 1: Raji cell lysate Lane 2: Ramos cell lysate Lane 3: 293T cell lysate (negative) Lane 4: Daudi cell lysate Lane 5: K-562 cell lysate (negative) Lysates/proteins at 20 µg/Lane. Predicted band size: 61 kDa Observed band size: 100 kDa Exposure time: 25 seconds; ECL: K1801; 4-20% SDS-PAGE gel. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA723533) at 1/50,000 dilution was used in primary antibody dilution (K1803) at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature. |

Fig2:
Immunocytochemistry analysis of Raji (positive) and 293T (negative) labeling CD19 with Rabbit anti-CD19 antibody (HA723533) at 1/2,000 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Rabbit anti-CD19 antibody (HA723533) at 1/2,000 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488, HA1121) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI. Beta tubulin (HA601187, red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594, HA1126) was used as the secondary antibody at 1/1,000 dilution. |

Fig3:
Flow cytometric analysis of K-562 (left, negative) and Ramos (right, positive) cells labeling CD19. Cells were washed twice with cold PBS and resuspend. Then stained with the primary antibody (HA723533, 1/5,000) (red) compared with Rabbit IgG Isotype Control (green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Rabbit IgG Secondary antibody (HA1121) at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black). |

Fig4:
Flow cytometric analysis of human peripheral blood cells labeling CD19 (HA723533), counterstained with CD3-PE. Cells were washed twice with cold PBS and resuspend. Then stained with the primary antibody (HA723533, 1/1,000). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Rabbit IgG Secondary antibody (HA1121) at 1/1,000 dilution for 30 minutes at +4℃. |
