Notiz: It is better to use new beakers, glass rods and glass pipettes or disposable plastic ware when making reagent to avoid phosphorus pollution.

Produktbeschreibung:

Ca++Mg++-ATPase is widely distributed in plants, Tiere, microorganisms and cells, which catalyzes the hydrolysis of ATP to form ADP and inorganic phosphorus.

Ca++Mg++-ATPase decomposes ATP to produce ADP and inorganic phosphorus. The activity of ATPase can be detected by measuring the amount of inorganic phosphorus.

Notiz

1. This kit can detect 24 tubes of Ca++Mg++ -ATPase samples in 50 tubes for each sample need one tube as control.
2. This method has the characteristics of trace, sensitive and rapid. The test tubes used for determination are phosphate-free strictly. Avoiding phosphorus pollution is the key to the success of detection.

Experimentelles Beispiel:

1. Take of pancreas and add 1 mL of Reagent I for ice bath homogenization. After centrifugation at 4℃ for 10 Mindest, the supernatant is put on the ice and operated according to the determination steps. ΔAT = 0.916-0.389=0.527, ΔAS =0.398-0.004=0.394

Ca++Mg++- ATPase activity (U/g-Masse) = 7.5 × ΔAT ÷ΔAS ÷ W = 100.32 U/g-Masse.

2. Take 0.1g of willow and add 1 mL of Reagent Ⅰ for ice bath homogenization. After centrifugation at 4℃ for 10 Mindest, the supernatant is put on ice and operated according to the determination steps. The ΔAT=0.137-0.124=0.013, and the ΔAS=398-0.004=0.394

Ca + + Mg + + – ATPase activity (U/g-Masse) = 7.5×ΔAT ÷ ΔAS ÷ W = 2.47 U/g-Masse.
