The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
2-4 units per mg protein. One unit is defined as the amount of enzyme that hydrolyzes one µmole of Suc-Ala-Ala Pro-Phe-pNA (1 mM) per minute at 25°C in 160 mM Tris-HCl, pH 7.4, with 1.6 M NaCl.
Additional notesProtein Determination: Extinction Coefficient (E) 0.1% at 280nm, 1cm pathway = 0.66.
Prepared from whole blood shown to be non reactive for HBsAg, anti-HCV, anti- HBc, and negative for anti-HIV 1 & 2 by FDA approved tests.
