Scientific Data Images for Human Serpin B3/SCCA1 Antibody

Detection of Human Serpin B3/SCCA1 antibody by Western Blot.

Detection of Human Serpin B3/SCCA1 by Western Blot.

Western blot shows lysates of A431 human epithelial carcinoma cell line. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-Human Serpin B3/SCCA1 Monoclonal Antibody (Catalog # MAB6528) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Serpin B3/SCCA1 at approximately 48 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Serpin B3/SCCA1 antibody in Human Squamous Cell Carcinoma by Immunohistochemistry (IHC-P).

Serpin B3/SCCA1 in Human Squamous Cell Carcinoma.

Serpin B3/SCCA1 was detected in immersion fixed paraffin-embedded sections of human squamous cell carcinoma using Mouse Anti-Human Serpin B3/SCCA1 Monoclonal Antibody (Catalog # MAB6528) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in cancer cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Serpin B3/SCCA1

Serpin B3, also known as Squamous Cell Carcinoma Antigen-1 (SCCA1), is a member of the serpin superfamily of serine protease inhibitors (1). Serpins primarily inhibit serine proteases and some are known to inhibit caspases and papain-like cysteine proteases (1). Serpin B3 belongs to the subgroup ovalbumin-related serpins which are involved in the regulation of apoptosis, inflammation, angiogenesis and embryogenesis (2). Serpin B3 was initially isolated from human cervical squamous cell tissue. It is a tumor marker for squamous cell carcinomas in various areas including the cervix, head, neck and lung (3). Unlike typical serpins, Serpin B3 shows inhibitory activity against papain-like lysosomal cysteine proteases Cathepsin K, L, and S, while lacking inhibitory activity against serine proteases (4).
