Frequently Asked Questions
Application
The assay used is fluorometric and therefore, is 10-100 times more sensitive than the colorimetric measurement. It is linear over a wide range of enzyme concentrations, which makes it particularly well suited for comparative analysis.
The reporter gene, encoding for alkaline-phosphatase, offers great advantages:
• The enzyme is highly stable.
• The assay is safe and easy to use. It provides rapid and reproducible results.
• When using the mutated version of the human placental alkaline phosphatase (SEAP) which is secreted out of the cells, enzyme activity in the same cell sample can be measured nondestructively and repeatedly over time using an aliquot of the culture medium. This saves the time required for cell extract preparations.
Other Notes
The kit contains buffers, substrate, and control enzyme for an easy and rapid alkaline-phosphatase reporter gene activity assay.
