The isomeric 6-TAMRA, SE is an amine-reactive form of tetramethylrhodamine. The single-isomer preparations of TAMRA are most important for high-resolution techniques such as DNA sequencing and capillary electrophoresis. 6-TAMRA is one of the traditional

7-Amino-4-methylcoumarin (AMC) can be used as a fluorescence reference standard for AMC-based enzyme substrates including AMC-based caspase substrates. The fluorescence spectra of AMC is not subject to variability due to pH-dependent protonation/deproton

Thermo Scientific™ Pierce 8M Guanidine-HCl Solution is an accurately formulated, ready-to-use solution of guanidine hydrochloride, that can be easily diluted and pH-adjusted to any concentration below 8M. Highlights:Any concentration below 8 M can be qui

Acryloyl-X, SE (6-((acryloyl)amino)hexanoic acid, succinimidyl ester) is an amine-reactive molecule that enables crosslinking of acrylamide to proteins and other biomolecules containing amines. The succinimidyl ester of acryloyl-X covalently reacts with
