如何查找COA批号
批号可以在产品标签上"批“ (Lot或Batch)字后面找到。
如果您查询到的批号为 TO09019TO 等,请输入去除前两位字母的批号:09019TO。
如果您查询到的批号含有填充代码(例如05427ES-021),请输入去除填充代码-021的批号:05427ES。
如果您查询到的批号含有填充代码(例如 STBB0728K9),请输入去除填充代码K9的批号:STBB0728。
部分情况下,可能未在线提供COA。如果搜索不到COA,可在线索取。
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
Stock solutions of RNase A can be made in 10 mM Tris-HCl, pH 7.5, 15 mM NaCl at a concentration of 10 mg/mL.
This product is stable for at least 3 years when stored properly at -20 °C.
RNase A solutions can be stored, aliquoted and frozen at -20 °C.
Boiling of stock solutions to inactivate residual DNase is not necessary and may cause precipitation of RNase with loss of enzymatic activity.
We suggest using RNase A at a concentration of 10 ug/ml.
The lot specific COA document can be found by entering the lot number above under the "Documents" section.

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.
