Substrati fluorogenici

4-Methylumbelliferyl-phosphoethanolamine is a phosphorylated substrate that can be used in the detection of enzymes such as alkaline phosphatase, esterase, and lipase. This compound has been shown to be a fluorescent and chromogenic substrate for many diagnostic purposes. 4-Methylumbelliferyl-phosphoethanolamine is also used as a fluorogenic substrate for chemiluminescent reactions that are found in culture media and environmental testing.

3-Carboxyumbelliferyl b-D-galactopyranoside is a fluorescent probe that can be used to study protein synthesis in live cells. It binds to the active site of the enzyme peptidyl transferase, which catalyzes the covalent linkage of amino acids to form a polypeptide chain. 3CMBG is specific for the amino acid proline and is a substrate for peptidyl transferase. The fluorescence of 3CMBG increases when it is bound to peptidyl transferase, making it useful as a marker for protein synthesis.

4-Methylumbelliferyl 2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-a-D-glucopyranoside is a chromogenic substrate for enzymes that catalyze the hydrolysis of glycosidic bonds. It can be used in diagnostic tests to identify antibodies against certain bacteria and fungi. The fluorogenic form of 4-methylumbelliferyl 2-acetamido-3,4,6-triO acetyl -2 deoxy a D glucopyranoside can be used as a chemiluminescent substrate for detecting bacterial activity. 4 methylumbelliferyl 2 acetamido 3,4,6 triO acetyl -2 deoxy a D glucopyranoside is also useful in bioluminescent assays to detect ATP production in bacteria and other microorganisms.

4-Methylumbelliferyl b-D-chitobiose heptaacetate is a fluorogenic substrate that is widely used in diagnostic and research applications. It can be used as a substrate for enzymes such as alkaline phosphatase, β-glucuronidase, β-galactosidase, β-glucosidase, α-amylase, α-glucosidase, α-mannosidase, and α-fucosidase. 4MUBH can also be used in the detection of bacterial growth. 4MUBH reacts with NADPH to produce light through chemiluminescence. This product has been shown to have a high purity and quality and should not be stored in UV light or strong acids. CAS No. 55900-34-0

4-Trifluoromethylumbelliferyl a-D-N-acetylneuraminic acid is a fluorescent chemiluminescent substrate that is used in the detection of beta-galactosidase activity. Beta-galactosidase catalyzes the hydrolysis of 4-trifluoromethylumbelliferyl a-D-N-acetylneuraminic acid to form 4-trifluoromethylumbelliferone and D-galactose, which emits light at approximately 480 nm. This reaction can be detected by fluorescence spectrophotometry using a fluorometer or photometer. 4TFUNA is not toxic, does not inhibit enzymes, and has been tested for toxicity and mutagenicity using bacteria and mammalian cells.

4-Methylumbelliferyl beta-D-gentiotrioside is a fluorogenic substrate for beta-glucosidase. After enzymatic cleaveage, free 4-methylumbelliferone (also known as hymecromone) is released, exhibiting blue fluorescence upon excitation with UV light. The strongest fluorescence of 4-methylumbelliferone requires deprotonation of the hydroxyl group (thus requires alkaline pH), with a maximal fluorescence intensity obtained with excitation at 350 to 370 nm and emission at 440 to 470 nm. The use of 4-methylumbelliferyl beta-D-gentiotriosideas a substrate for measuring the beta-glucosidase activity is used for Gaucher disease screening.

4-Methylumbelliferyl 2-acetamido-3-O-(2,3,4-tri-O-acetyl-a-L-fucopyranosyl)-4-O-(2,3,4,6 -tetra-O-acetylbDgalactopyranosyl)-6-O-acetyldEoxybDglucopyranoside is a chemiluminescent substrate that has been used in the detection of beta galactosidase activity. It is a ligand for beta galactosidases and can be used for the study of enzyme kinetics. This compound also exhibits high purity and is available in CAS number: 916071. 4MUFAGAALF is suitable for use in culture media and environmental testing as well as diagnostics (e.g., bioluminescence), staining (fluorogenic substrate), and chromogenic substrates
