Scientific Data Images for Human SLPI Antibody

SLPI antibody in Human Lung by Immunohistochemistry (IHC-P).

SLPI in Human Lung.

SLPI was detected in immersion fixed paraffin-embedded sections of human lung using Goat Anti-Human SLPI Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1274) at 10 µg/mL overnight at 4 °C. 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 cell surfaces and cytoplasm. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Applications for Human SLPI Antibody

Application
Recommended Usage

Immunohistochemistry

5-15 µg/mL
Sample: Immersion fixed paraffin-embedded sections of human lung

Western Blot

0.1 µg/mL
Sample: Recombinant Human SLPI (Catalog # 1274-PI)

Neutralization

Measured by its ability to neutralize Recombinant Human SLPI (0.125 µg/mL, Catalog # 1274-PI) inhibition of Trypsin (0.05 µg/mL) cleavage of the fluorogenic peptide substrate Mca-RPKPVE-Nval-WRK(Dnp)-NH2 (10 µM, Catalog # ES002). The Neutralization Dose (ND50) is typically 2 µg/mL.

Background: SLPI

SLPI is a member of the Serpin family and is primarily expressed in secretory glandular epithelial cells. It is found in various secretory fluids and functions as a potent inhibitor of many proteolytic enzymes. SLPI can modulate cell proliferation and has been shown to have anti-inflammatory, anti-viral, and anti-bacterial activities (1, 2).
