Introduction
Napsin A Aspartic Peptidase, also known as NAPSA is a member of the
peptidase A1 family. NAPSA is involved in the processing of pneumocyte
surfactant precursors. Furthermore the activation peptides of aspartic proteinases
take part as inhibitors of the active site. These peptide segments/pro-parts are
considered essential for correct folding, targeting, as well as control of the
activation of aspartic proteinase zymogens. The pronapsin A gene is expressed mostly
in lung and kidney. In addition, NAPSA translation product is expected to be a
fully functional, glycosylated aspartic proteinase precursor which contains an
RGD motif as well as an additional 18 residues at its C-terminus.
Description
NAPSA Human Recombinant produced in E.Coli is a single, non-glycosylated
polypeptide chain containing 380 amino acids (64-420 a.a) and having a
molecular mass of 40.9kDa.
NAPSA is fused to a 23 amino acid His-tag at N-terminus
& purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile filtered colorless solution.
Formulation
NAPSA protein solution (0.25mg/ml) containing 20mM
Tris-HCl (pH8.0) and 10% glycerol.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
