Data Examples

Western Blot Detection  of Human Napsin A by Western Blot. View Larger

Detection of Human Napsin A by Western Blot. Western blot shows lysates of human lung tissue and human kidney tissue. PVDF membrane was probed with 0.5 µg/mL of Rabbit Anti-Human Napsin A Monoclonal Antibody (Catalog # MAB8489) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Napsin A at approximately 35 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Immunohistochemistry Napsin  A in Human Kidney. View Larger

Napsin A in Human Kidney. Napsin A was detected in immersion fixed paraffin-embedded sections of human kidney using Rabbit Anti-Human Napsin A Monoclonal Antibody (Catalog # MAB8489) at 1 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Rabbit HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS005) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in convoluted tubules. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Simple Western Detection  of Human Napsin A by Simple WesternTM. View Larger

Detection of Human Napsin A by Simple WesternTM. Simple Western lane view shows lysates of human lung tissue, loaded at 0.2 mg/mL. A specific band was detected for Napsin A at approximately 46 kDa (as indicated) using 5 µg/mL of Rabbit Anti-Human Napsin A Monoclonal Antibody (Catalog # MAB8489). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: Napsin A

Novel Aspartic Proteinase of the Pepsin Family or Napsin A is an aspartic proteinase that belongs to the peptidase A1 family and plays a role in pneumocyte surfactant processing. It consists of a 24-residue signal peptide, a 40-amino acid propart, the mature enzyme of 336 amino acids, and a C-terminal extension of 18 residues. Highest levels of Napsin A have been detected in adult lung (type II pneumocytes), fetal lung, and kidney tissues. Napsin A is also expressed at lower levels in adult spleen and at very low levels in peripheral blood leukocytes. Human napsin A shares 72.6% sequence identity with the mouse homolog.
