N-Hydroxysuccinimide (NHS) esters are reactive species which couple with amines efficiently. This type of activated esters is particularly suitable for the labeling of biomolecules in aqueous environments.
Product category
Sulfotetrafluorophenyl ethers (STP ethers) are reactive derivatives that react efficiently with primary amines to form the same acylation products as NHS esters. They are dramatically more water-soluble than the corresponding N-hydroxysuccinimidyl (NHS) esters, making them ideal for labeling biomolecules in an aqueous environment.
Product category
Tetrafluorophenyl ethers (TFP ethers) are reactive derivatives that react efficiently with primary amines to form the same acylation products as NHS esters. They are more stable at the basic pH values typically associated with reactions with amines and are also less susceptible to spontaneous hydrolysis.
