STORAGE STABILITY
ORGANISM
UNIPROT
LITERATURE
-196°C, kept in liquid nitrogen exhibits only minor modifications
-
-20°C, 0.5 M phosphate buffer, pH 6.9, concentration of approximately 2.5% without noticeable loss of blue colour during 1 month
-
-20°C, 3 months
-
-20°C, A280:A610 ratio increases for several weeks on storage
-
-20°C, frozen in liquid nitrogen 0.2% enzyme solution in 0.015 M phosphate buffer, pH 6.9, containing 0.1 M NaCl loses its blue colour completely after 2 weeks storage
-
-20°C, storage induced heterogeneity and decrease of the oxidase activity
-
-90°C, when frozen in dry ice and thawed, about 5% of the absorbance at 610 nm is lost, no change in the absorbance at 280 nm
-
4°C, 0.1 M Tris buffer, pH 8.0, decomposes into fragments when stored for 36-48 h
-
4°C, 0.2% enzyme solution in 0.015 M phosphate buffer, pH 6.9, containing 0.1 M NaCl: the A610/A280 ratio is reduced by approximately 10% in 1 month
-
4°C, 0.5 M sodium phosphate buffer, pH 7.0, retains catalytic activity for at least 3 weeks
-
4°C, ferroxidase II, purified enzyme is stable for at least 2 weeks
-
4°C, purified enzyme sensitive to storage, no oxidase activity after 4 months
