Napsin A Antibody (A9C1-R)

Immunohistochemistry: Napsin A Antibody (A9C1-R) [NBP3-32633] - Immunohistochemical analysis of paraffin-embedded human kidney tissue with Mouse anti-Napsin A antibody (NBP3-32633) at 1/2,000 dilution. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (NBP3-32633) at 1/2,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background

Napsin is a pepsin-like aspartic proteinase, in the A1 clan of the AA clade of proteinases. Other AA family proteinases include Pepsin, cathepsin-D, cathepsin-E and rennin. Of these proteinases, napsin is most closely related to cathepsin-D, sharing 46% identity at the amino acid level. There are two closely related Napsins, napsin A and napsin B, with 85% overall identity at the amino acid level. There are three isoforms. Napsin-A is also termed napsin-1, or TA02, a Tumor Adenocarcinoma marker. Napsin A may be involved in processing of pneumocyte surfactant precursors.
