Enzyme Substrates and Kits for Cell Regulatory Enzymes.

These products have been developed exclusively for use in cell systems expressing a common marker gene in order to modutate their physiology, growth (inhibit or enhance cell growth) or secondary gene expression. They are intended for research use only. Contact our technical assistance staff for more information about the use of these new products for use in your cell systems.

Product ID Product Name Description
M0149 Dexamethasone-21-O-ß-D-Galactopyranoside  Cleavage product: Upon enzymatic or chemical hydrolysis of the galactoside group, dexamethasone is produced. Dexamethasone is a useful inducer of gene expression when combined with a dexamethasone-inducible promoter system, and is also a potent glucocorticoid anti-inflammatory. Dexamethasone has also been used as an inducer of apoptosis in tumor cells.  
M0165 Chloramphenicol ß-D-Galactoside  Cleavage product: Upon enzymatic or chemical hydrolysis of the galactoside group, chloramphenicol, an antibiotic (bacteriostatic), is produced. 
M0174 5-Fluorouridine 5-O-ß-D-Galactopyranoside  This analog of 5-fluorouridine (5-FUR) is useful for lacZ specific release of 5-FUR in recombinant cells or tissues. 5-FUR is a potent anti-metabolite, with mode of action by inhibition of thymidylate synthetase or by incorporation into RNA in vivo.  
M0176 Tetracycline 10-O-ß-D-Galactopyranoside  Tetracycline analog useful as an antibiotic for specific release in lacZ transfected cells and tissues. 
M0182 7-N-Benzoyl-Cephalosporanic acid, L-glutamate ester  This conjugate of Cephalosporin C and glutamate is useful for release of the essential amino-acid L-glutamate, upon action of ampicillinase (beta-lactamase activity) in amp-positive cell lines from vectors incorporating the amp (selection) marker gene. 
M0220 1,2-di-O-Octanoyl Galactopyranosyl rac-glycerol  This synthetic diglyceride analog is an activator of protein kinase C, that is released upon action of beta-galactosidase in lacZ transfected cells and tissues. 
M0224 1-O-Oleoyl-2-O-acetyl-3-O-ß-D-Galactopyranosyl syn-Glycerol  This synthetic diglyceride analog is an activator of protein kinase C, that is released upon action of beta-galactosidase in lacZ transfected cells and tissues. 
M0304 Pyridoxine Galactoside  This pyridoxine (vitamin B6) analog is a useful tissue culture component that will release pyridoxine upon action of lacZ beta-galactosidase. 
M0326 Myo-inositol galactoside  This galactoside derivative of myo-inositol will release myo-inositol upon action of beta-galactosidase. myo-Inositol is a component of membrane phospholipids, glycophosphatidylinositol anchors that bind glycoproteins to cell membranes and a precursor of inositol phosphates that act as second messengers in vivo. This derivative can also be used as a tissue culture media component that will be selectively released in lacZ transfected cell lines. 
M0328 Riboflavin galactoside  This analog of riboflavin (vitamin B2) releases riboflavin upon action of beta-galactosidase enzyme activity. Riboflavin is a common component of tissue culture media and M0328 can be used to select for lacZ transfected cells in culture. 
M0330 Pyridoxal galactoside  This pyridoxine (vitamin B6) analog is a useful tissue culture media component that will release pyridoxal upon action of lacZ beta-galacotsidase. Useful as a media component for selection of lacZ positive cells in culture. 
M0338 Pantothenic acid 2,4-di-O-ß-D-Galactopyranoside  This analog of pantothenic acid (vitamin B5) releases pantothenic acid upon action of beta-galactosidase enzyme activity. Pantothenic acid is a common component of tissue culture media and M0338 can be used to select for lacZ transfected cells in culture. 
M0351 Thiamine Galactoside  This thiamine (vitamin B1) analog is a useful tissue culture component that will release thiamine upon action of lacZ beta-galacotsidase activity. Useful for selection of lacZ transfected cell lines in culture. 
M0630 Bromoxynil glucuronic acid triacetate methyl ester  Bromoxynil is a nitrile herbicide that is used for post-emergent control of annual broadleaf weeds. It is especially effective in the control of weeds in cereal, corn, sorghum, onions, flax and mint. This bromoxynil derivative can be used for selective release in GUS-positive plant systems, in a tissue specific manner. The compound works by inhibiting photosynthesis in the target plants. This beta-glucuronide derivative lacks activity until acted upon by intracellular beta-glucuronidase (cloned with the GUS marker gene). Additional ester groups help with cell permeation of this herbicide derivative. 
M0632 Bromoxynil glucuronic acid methyl ester  Bromoxynil is a nitrile herbicide that is used for post-emergent control of annual broadleaf weeds. It is especially effective in the control of weeds in cereal, corn, sorghum, onions, flax and mint. This bromoxynil derivative can be used to selectively ablate GUS-positive cells and tissues in plant systems. The compound works by inhibiting photosynthesis in the target plants. This beta-glucuronide derivative lacks activity until acted upon by intracellular beta-glucuronidase (cloned with the GUS marker gene). The methyl ester helps with cell permeation in vivo.
