Scientific Data Images for Human Serpin B2 Antibody
Detection of Human Serpin B2 by Western Blot.
Western blot shows lysates of U937 human histiocytic lymphoma cell line untreated (-) or treated (+) with PMA and HEK001 human epidermal keratinocyte cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human Serpin B2 Monoclonal Antibody (Catalog # MAB8550) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Serpin B2 at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Serpin B2 in U937 Human Cell Line by Flow Cytometry.
U937 human histiocytic lymphoma cell line either untreated (upper panel) or treated with PMA and Calcium Ionomycin for 2 days (lower panel) was stained with Mouse Anti-Human Serpin B2 Monoclonal Antibody (Catalog # MAB8550, filled histogram) or isotype control antibody (Catalog # MAB0041, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B).
Serpin B2 in U937 Human Cell Line.
Serpin B2 was detected in immersion fixed U937 human histiocytic lymphoma cell line stimulated with PMA using Mouse Anti-Human Serpin B2 Monoclonal Antibody (Catalog # MAB8550) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: Serpin B2
Serpin B2, also known as Plasminogen Activator Inhibitor 2 (PAI-2), is a 415 amino acid serine-type endopeptidase inhibitor with high expression in blood, vasculature and placenta. Its expression is upregulated in pregnancy and in activated monocytes/macrophages by a wide range of viral, bacterial and parasitic agents. Serpin B2 is upregulated in monocytes from HIV-1 infected patients, and is thought to modulate Th1/Th2 responses. Serpin B2/PAI-2 colocalizes with CHL1 and Vitronectin and mediates neurite outgrowth during post-natal brain development. Inhibition of uPA by SerpinB2 in tumors is associated with a favorable prognosis.
