Anti-CD19 Antibody (R31973)

CD19 Antibody Human Appendix IHC. Immunohistochemistry analysis of FFPE human appendix tissue using CD19 Antibody. Heat induced antigen retrieval was performed by boiling tissue sections in pH 8 EDTA buffer for 20 minutes prior to staining. Strong membranous staining is observed in lymphoid cell populations, consistent with CD19 expression on B cells within immune tissue. These results support the use of CD19 Antibody for studying B cell markers, immune cell identification and lymphocyte-associated pathways.

CD19 Antibody Human Tonsil IHC. Immunohistochemistry analysis of FFPE human tonsil tissue using CD19 Antibody. Heat induced antigen retrieval was performed by boiling tissue sections in pH 6 citrate buffer for 20 minutes prior to staining. Strong membranous staining is observed in B cell populations within lymphoid tissue, consistent with CD19 expression as a B lymphocyte marker. These results support the use of CD19 Antibody for studying B cell identification, immune cell populations and lymphocyte development pathways.

CD19 Antibody Human B Cell WB. Western blot analysis of human B cell lysates using CD19 Antibody / B Cell Marker Antibody. Lane 1: Raji cells; Lane 2: Ramos cells; Lane 3: Daudi cells. Specific bands are detected between approximately 60–100 kDa, consistent with the expected molecular weight range of glycosylated CD19 protein. These results support the use of CD19 Antibody / B Cell Marker Antibody for studying B lymphocyte markers, immune cell identification and hematopoietic cell signaling pathways.

CD19 Antibody Human Tonsil IF. Immunofluorescence analysis of FFPE human tonsil tissue using CD19 Antibody / B Cell Marker Antibody. Heat induced antigen retrieval was performed using pH 8 EDTA buffer, and the tissue section was incubated with the primary antibody at 5 ug/ml overnight at 4°C. CD19 expression is shown in red with DAPI nuclear counterstain shown in blue. Strong membranous staining is observed in B cell populations, supporting the use of CD19 Antibody / B Cell Marker Antibody for studying B lymphocyte markers, immune cell localization and immune tissue organization.
