Will your Cell Lysis Buffer (10X) #9803 retain enzymatic activity?

We do not perform enzymatic activity assays internally using the Cell Lysis Buffer (10X) #9803, so we are unable to guarantee that the enzymatic activity will be conserved. We routinely use this buffer in immunoassays such as western immunoblot, IP, and ELISA without issue.

As a reference, the components of the Cell Lysis Buffer (10X) #9803 are provided below:
20 mM Tris-HCl (pH 7.5), 150 mM NaCl, 1 mM Na₂EDTA, 1 mM EGTA, 1% Triton, 2.5 mM sodium pyrophosphate, 1 mM beta-glycerophosphate, 1 mM Na₃VO₄, 1 µg/ml leupeptin
