Beta-glucuronidases are members of the glycosidase family of enzymes that catalyze the breakdown of complex carbohydrates. Human β-glucuronidase is a type of glucuronidase that catalyzes hydrolysis of β-D-glucuronic acid residues from the non-reducing end of mucopolysaccharides, such as...

L-glutamine is an essential amino acid that is a crucial component of culture media that serves as a major energy source for cells in culture. L-glutamine is very stable as a dry powder and as a frozen solution. In liquid media or stock solutions, however, L-glutamine degrades relatively rapidly....

Hydroxyurea is a inhibitor of DNA synthesis in vivo, and an antiviral and antineoplastic agent which is S-phase specific.
