Features and Benefits
Analysis Note
Other Notes
Das Kochen von Stammlösungen dieses RNase-A-Produkts zur Inaktivierung von DNase-Resten ist nicht erforderlich und kann zur Ausfällung von RNase und möglicherweise einem Verlust der Enzymaktivität führen. Wenn eine RNase-A-Lösung bei neutralem pH-Wert erhitzt wird, findet eine Ausfällung statt. Bei Erhitzung bei einem niedrigeren pH-Wert findet aufgrund vorhandener Proteinverunreinigungen eine gewisse Ausfällung statt.

Why is RNase A activity not listed as micromoles per minute, and what is a Kunitz unit?
1 answer-
The Kunitz unit was created to reflect the non-linear nature of the RNAse enzymatic reaction. As the reaction progresses the activity changes due to RNA as a heterogeneous polymeric substrate; therefore, the unit of moles or micomoles per minute becomes inaccurate. As such, our enzymatic assay describes a unit that varies throughout the reaction: One unit will cause a decrease of 100% per minute in the value of E0 - Ef at pH 5.0 at 25°C. Ef is determined in the RNAse control step, while E0 reflects the current reaction rate.
