TCL1B in Human Lymphoma. TCL1B was detected in immersion fixed paraffin-embedded sections of human lymphoma using Goat Anti-Human TCL1B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6794) at 3 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013 ). Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008 ) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm.
