Detection of Human ST8 a-2,8-Sialyltransferase 8A/ ST8SIA1 by Western Blot. Western blot shows lysates of Hs 294T human melanoma cell line, SK-Mel-28 human malignant melanoma cell line, A375 human melanoma cell line, and Bowes human melanoma cell line. PVDF membrane was probed with 2 µg/mL of Sheep Anti-Human ST8 a-2,8-Sialyltransferase 8A/ST8SIA1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6716) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016 ). A specific band was detected for ST8 a-2,8-Sialyltransferase 8A/ST8SIA1 at approximately 48-50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1 .
ST8 a-2,8-Sialyltransferase 8A/ST8SIA1 in Human Breast Cancer Tissue. ST8 a-2,8-Sialyltransferase 8A/ST8SIA1 was detected in immersion fixed paraffin-embedded sections of human breast cancer tissue using Sheep Anti-Human ST8 a-2,8-Sialyltransferase 8A/ST8SIA1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6716) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019 ) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm of epithelial cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections .
