Nonstick and laser-safe gold aids laser trapping of biomolecules
...ts are easy to lay down in desired patterns at the nanometer scale. Perkins group attached the DNA to the gold with sulfur-based chemical units called thiols
(widely used in nanotechnology), an approach that is mechanically stronger than the protein-based bonding techniques typically used in biology. The JI...
Progress toward an antitumor vaccine
... spacer, which has an allyl group (two carbon atoms attached by a double bond) at its end. The glycopeptide is coupled to a building block that causes thiols
(sulfur–hydrogen groups) to protrude from the molecule. In the next, light-initiated (photochemical) reaction, only the desired thioether bonds are fo...

Dithio-bis(2-nitrobenzoic acid) BioChemica from AppliChem GmbH
Description:... The chromogenic reactant should not interfere with the enzymic reaction.
5,5'-Dithiobis-2-nitrobenzoic acid (DTNB, Ellman's reagent) reacts with free thiols
in an exchange reaction that produces the yellow 4-nitrothiolate anion. For the assay of acetylcholine esterase (E.C. 18.104.22.168), acetylthiocholine iodi...
IMPACT-CN System from New England Biolabs
Description:...f the intein and the chitin binding domain (5), to either the C-terminus (pTYB1,2) or N-terminus (pTYB11,12) of the target protein. In the presence of thiols
such as DTT, -mercaptoethanol or cysteine, the intein undergoes specific self-cleavage which releases the target protein from the chitin-bound intein ...

Total Antioxidant Power Colorimetric Assay Kit from Neogen Corporation
Description:...th intra- and extracellular). Lipid soluble antioxidants (most importantly vitamin E) and water-soluble antioxidants (uric acid, vitamin C, bilirubin, thiols
and gluthathione) are involved in these processes. Given the multiplicity of antioxidant pathways, their centrality in the prevention of oxidant stres...
