Opis

General description

A non-metal complexing, zwitterionic buffer with mixed-mode dissociation constants of pK_a1 = 3.73 and pK_a2 = 7.96 (aqueous solution, 25°C, ionic strength = 100 mM). PIPPS has no interference at wavelengths longer than 240 nm.

Preparation Note

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 3 months at -20°C.
