Western blot analysis of CD19 using anti-CD19 antibody (PB9800). The sample well of each lane was loaded with 30 ug of sample under reducing conditions.
Lane 1: human Raji whole cell lysates,
Lane 2: human Ramos whole cell lysates,
Lane 3: human Daudi whole cell lysates,
Lane 4: human Jurkat whole cell lysates.
After electrophoresis, proteins were transferred to a membrane. Then the membrane was incubated with rabbit anti-CD19 antigen affinity purified polyclonal antibody (PB9800) at a dilution of 1:1000 and probed with a goat anti-rabbit IgG-HRP secondary antibody (Catalog # BA1054). The signal is developed using ECL Plus Western Blotting Substrate (Catalog # AR1197). A specific band was detected for CD19 at approximately 95 kDa. The expected band size for CD19 is at 61 kDa.

IHC analysis of CD19 using anti-CD19 antibody (PB9800) .
CD19 was detected in a paraffin-embedded section of human appendix tissue. The tissue section was incubated with rabbit anti-CD19 Antibody (PB9800) at a dilution of 1:200 and developed using HRP Conjugated Rabbit IgG Super Vision Assay Kit (Catalog # SV0002) with DAB (Catalog # AR1027) as the chromogen.

IF analysis of CD19 using anti-CD19 antibody (PB9800).
CD19 was detected in a paraffin-embedded section of human tonsil cancer tissue. The tissue section was incubated with rabbit anti-CD19 Antibody (PB9800) at a dilution of 1:100. Fluoro594-conjugated Anti-rabbit IgG Secondary Antibody (red) (Catalog # BA1142) was used as secondary antibody. The section was counterstained with DAPI (Catalog # AR1176) (Blue).
