Recombinant Napsin A Antibody / Rabbit Monoclonal

SKU: orb606458

Description

Napsin is a pepsin-like aspartic proteinase connected with maturation of surfactant protein B. There are two closely related napsins, napsin A and napsin B. Napsin A is expressed as a single chain protein. Immunohistochemical studies revealed high expression levels of napsin A in human lung and kidney but low expression in spleen. Napsin A is expressed in type II pneumocytes and in adenocarcinomas of lung. The high specificity expression of napsin A in adenocarcinomas of lung is useful to distinguish primary lung adenocarcinomas from adenocarcinomas of other organs.

Images & Validation

• Tested Applications: IHC-P, WB
• Dilution Range: Immunohistochemistry (FFPE): 1-2ug/ml for 30 min at RT,Western blot: 2-4ug/ml
• Reactivity: Human
• Application Notes:
  The stated application concentrations are suggested starting points. Titration of the recombinant Napsin A antibody may be required due to differences in protocols and secondary/substrate sensitivity.1. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.

IHC testing of FFPE human lung adenocarcinoma with recombinant Napsin A antibody (clone NAPSA/1865R). Required HIER: boil tissue sections in pH9 10mM Tris with 1mM EDTA for 10-20 min followed by cooling at RT for 20 min.

SDS-PAGE analysis of purified, BSA-free recombinant Napsin A antibody (clone NAPSA/1865R) as confirmation of integrity and purity.
