Space Saver Option（チェックを入れると箱詰めから袋詰めに変更となりますのでご注意ください） Customers purchasing multiple kits may choose to save storage space by eliminating the kit packaging and receiving their multiplex assay components in plastic bags for more compact storage.
Native creatine phosphokinase from rabbit muscle. Catalyzes the conversion of creatine and ATP to creatine phosphate and ADP. Has an optimal pH of 9.0 for the forward reaction and 6.0-7.0 for the reverse reaction.

Product Information
CAS number
9001-15-4
Activity
≥300 units/mg (at 25°C); 750 units/mg (at 37°C)
Unit of Definition
One unit is defined as the amount of enzyme that will catalyze the conversion of 1.0 µmol creatine phosphate per min at 25°C or 37°C, pH 6.8.
Following reconstitution in 0.5% NaHCO₃, refrigerate (4°C). Do not freeze or shake, as SH groups may be oxidized and form linkages between protein molecules, resulting in precipitation, turbidity, and loss of activity. NaHCO₃ stock solutions are stable for 2-3 days at 4°C. Following reconstitution in 0.1 M imidazole buffer, aliquot and freeze (-20°C). Imidazole stock solutions are stable for up to 4 weeks at -20°C. Avoid freeze/thaw cycles, as 20-30% of activity will be lost with each freeze/thaw cycle.
Note that this data sheet is not lot-specific and is representative of the current specifications for this product. Please consult the vial label and the certificate of analysis for information on specific lots. Also note that shipping conditions may differ from storage conditions.

Special Instructions
Following reconstitution in 0.5% NaHCO₃, refrigerate (4°C). Do not freeze or shake, as SH groups may be oxidized and form linkages between protein molecules, resulting in precipitation, turbidity, and loss of activity. NaHCO₃ stock solutions are stable for 2-3 days at 4°C. Following reconstitution in 0.1 M imidazole buffer, aliquot and freeze (-20°C). Imidazole stock solutions are stable for up to 4 weeks at -20°C. Avoid freeze/thaw cycles, as 20-30% of activity will be lost with each freeze/thaw cycle.
