4 methylumbelliferyl b d galactopyranoside for β gal

Manufactured by Merck Group
Sourced in Germany

4-methylumbelliferyl b-D-galactopyranoside is a fluorogenic substrate used to detect and quantify the enzyme β-Galactosidase (β-Gal) activity. Upon cleavage by β-Gal, the compound releases a fluorescent 4-methylumbelliferone product that can be measured.

Cultured primary urinary cells were collected in cold PBS. Cell lysis was performed by freezing and thawing over five cycles. Enzyme activity for α-Galactosidase A (α-Gal) and β-Galactosidase (β-Gal) was measured after incubation of lysed cells with 4-methylumbelliferyl a-D-galactopyranoside for α-Gal or 4-methylumbelliferyl b-D-galactopyranoside for β-Gal (Sigma, Taufkirchen, Germany) as described previously39 (link) α-Gal A activity was normalized to β-Gal activity, functioning as an internal control.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
