Background on Napsin A

Napsin-A is a human protein ecoded by the NAPSA gene. It has many roles including inhibition of active site, folding and control of certain zymogens. Napsin A is found in the lung and kidney.  Napsin A can be used to determine adenocarcinomasspecific to the lung. The affinity purified monoclonal antibody percolated on the ELISA plate and the affiniy purified polyclonal HRP conjugated detection antibody in this kit are selective to Napsin A.


Methods Overview
  1. Equilibrate plate to RT
  2. Add sample to plate, incubate overnight
  3. Add detection antibody, incubate 1 hr
  4. Add color reagents, 30 min
  5. Add stop solution.  Measure OD at 450nm
