Product Specification

Alternative Name:nNOS, NOS I
MW:~160kDa/subunit; homodimer.
Source:Produced in Sf9 insect cells. Produced in a baculovirus expression system.
UniProt ID:P29476
Formulation:Liquid. In 20mM TRIS/HCl (pH 7.5), 150mM sodium chloride, 4mM EGTA and 10mM 2-mercaptoethanol.
Purity:≥98% (SDS-PAGE)
Specific Activity:~0.5µmol L-citrulline/mg/min. Amount assayed: 0.1-0.3µl. Optimal conditions: pH 7.0; 37°C; 0.1mM L-arginine, 0.2mM NADPH, 10µM BH4, 5µM FAD/FMN, 10µg/ml calmodulin, 10-500µM CaCl2.
Application Notes:Useful tool for studying NOS enzyme regulation, screening inhibitors and other applications.
Shipping:Shipped on Dry Ice
Long Term Storage:-80°C
Use/Stability:Dilute stock solutions with buffer containing 10mM 2-mercaptoethanol and 1mM CHAPS.

nNOS is relatively unstable. Keep stock vial on ice at all times when performing experiments! Enzyme loses approx. 10-15% of activity during a single freeze/thaw cycle.
Handling:Avoid freeze/thaw cycles. After opening, prepare aliquots and store at -80°C.
