Napsin A Antibody

SKU: orb385916

Description

Napsin-A is a protein that in humans is encoded by the NAPSA gene. The activation peptides of aspartic proteinases plays role as inhibitors of the active site. These peptide segments, or pro-parts, are deemed important for correct folding, targeting, and control of the activation of aspartic proteinase zymogens. The pro-Napsin A gene is expressed predominantly in lung and kidney. Its translation product is predicted to be a fully functional, glycosylated aspartic proteinase precursor containing an RGD motif and an additional 18 residues at its C-terminus. [Wiki]

Western blot of 1) K562, 2) 293 and 3) A549 cell lysates using Napsin A antibody (clone NPSNA-1). Predicted molecular weight ~45 kDa.

IHC testing of FFPE human lung adenocarcinoma with Napsin A antibody (clone NPSNA-1). FFPE testing requires sections to be boiled in pH9 10 mM Tris with 1 mM EDTA for 10-20 minutes, followed by cooling at RT for 20 minutes, prior to staining.
