Human Napsin A ELISA Kit

Novel Aspartic Proteinase of the PepSIN Family (Napsin A, or NAPSA) belongs to the peptidase A1 family and plays a role in pneumocyte surfactant processing. It is also known as aspartyl protease 4 (ASP4), KAP, Kdap, napsin-1, NAP1, NAPA, and SNAPA. Two closely related proteins are known, Napsin A and Napsin B. Napsin A is a single-chain, 38 kDa protein. It is expressed at high levels in human lung and kidney, and at lower levels in spleen. Napsin A expression has been detected in type II pneumocytes and in lung adenocarcinomas.

This kit is a solid-phase sandwich ELISAs using two antibodies that are highly specific to human Napsin A protein; one is precoated on the ELISA plate and the other is HRP-conjugated. This kit can be used to measure soluble human Napsin A protein in serum, urine, or cell culture supernatant.
