Measuring \u3b2-galactosidase activity at pH 6 with a differential pH sensor
The \u3b2-Galactosidase activity at pH 6 is used as a cellular marker
to identify senescent cell cultures. The classic method to identify
this enzymatic activity is using cytochemical staining with X-Gal after
16 hrs. In this work, a differential pH sensor was used to measure
\u3b2- Galactosidase activity at pH 6. The measurement is easy and
only takes 3 min
Measuring β-galactosidase activity at pH 6 with a differential pH sensor
The β-Galactosidase activity at pH 6 is used as a cellular marker
to identify senescent cell cultures. The classic method to identify
this enzymatic activity is using cytochemical staining with X-Gal after
16 hrs. In this work, a differential pH sensor was used to measure
β- Galactosidase activity at pH 6. The measurement is easy and
