CD38 Antibody for FACS / CD38 Flow Cytometry Antibody (RQ5801)

CD38 Antibody human tonsil IHC. Immunohistochemistry analysis of CD38 / plasma cell marker expression in FFPE human tonsil using a CD38 antibody. Strong membranous and cytoplasmic HRP-DAB brown staining highlights numerous plasma cells and activated lymphocytes within the tonsillar interfollicular regions, with scattered positive cells extending into germinal center-associated areas. The staining pattern demonstrates dense immune cell distribution with clear contrast against predominantly negative background lymphocytes. HIER was performed by boiling tissue sections in pH 8 EDTA buffer for 20 minutes followed by cooling prior to antibody incubation.

CD38 Antibody human appendicitis tissue IHC. Immunohistochemistry analysis of CD38 / plasma cell marker expression in FFPE human appendicitis tissue using a CD38 antibody. Strong membranous and cytoplasmic HRP-DAB brown staining highlights abundant plasma cells and activated lymphocytes within inflamed lamina propria and peri-glandular regions, with dense immune cell infiltration surrounding epithelial structures. The staining pattern demonstrates prominent immune activation associated with inflammatory pathology, while epithelial cells remain largely negative. HIER was performed by boiling tissue sections in pH 8 EDTA buffer for 20 minutes followed by cooling prior to antibody incubation.

CD38 Antibody human lung cancer tissue IHC. Immunohistochemistry analysis of CD38 / plasma cell marker expression in FFPE human lung cancer tissue using a CD38 antibody. Strong membranous and cytoplasmic HRP-DAB brown staining highlights tumor-infiltrating plasma cells and activated lymphocytes within the tumor microenvironment, forming focal clusters along stromal and tumor interface regions. The staining pattern demonstrates immune cell infiltration associated with malignancy, while the majority of tumor cells remain negative. HIER was performed by boiling tissue sections in pH 8 EDTA buffer for 20 minutes followed by cooling prior to antibody incubation.

CD38 Antibody human A431 cells IF. Immunofluorescence analysis of CD38 / plasma cell marker expression in FFPE human A431 cells using a CD38 antibody (green). Signal is observed predominantly along the cell membrane and within the cytoplasm, outlining individual cells with a punctate to diffuse staining pattern, while nuclei are counterstained with DAPI (blue). The staining demonstrates cell surface-associated localization consistent with CD38 expression, with clear contrast between positive signal and nuclear regions. HIER was performed by steaming tissue sections in pH 6 citrate buffer for 20 minutes prior to antibody incubation.

CD38 Antibody human Raji lysate WB. Western blot analysis of CD38 / plasma cell marker expression in human Raji cell lysate using a CD38 antibody. A band is detected at approximately 40–45 kDa, consistent with the predicted molecular weight of CD38, with slight upward shift reflecting glycosylation of this cell surface protein. The observed band aligns with known expression of CD38 in B cell-derived lines.

CD38 Antibody for FACS. Flow cytometry analysis of CD38 / plasma cell marker expression in human Raji cells using CD38 Antibody for flow cytometry at 1 ug per million cells. The CD38 antibody (blue) demonstrates a clear right-shifted population compared to isotype control (green) and unstained cells (red), indicating strong cell surface expression of CD38. The distinct separation supports accurate gating and identification of CD38-positive B cell populations.
