General description

4-Methylumbelliferyl β-D-galactopyranoside (MUG) is a UV-absorbing dye that serves as a fluorescent substrate for β-galactosidase in a planar yeast estrogen screen (pYES) for the detection of estrogen active compounds.

Application

4-Methylumbelliferyl β-D-galactopyranoside has been used as a substrate in β-galactosidase activity assay.

The phytohormone 7-iso-(+)-jasmonoyl-L-isoleucine (JA-Ile) mediates plant defense responses against herbivore and pathogen attack, and thus increases plant resistance against foreign invaders. However, JA-Ile also causes growth inhibition; and therefore JA-Ile is not a practical chemical regulator of plant defense responses.

Mucopolysaccharidoses (MPS) are genetic disorders that affect up to 1 in 25,000 births. They are caused by dysfunctions of lysosomal hydrolases that degrade glycosaminoglycans (GAGs) which accumulate in cells, damaging their proper functioning. There are 7 types of MPS, distinguished
