Applications of FTI's molecular affinity tags range
from separations and scavenging in medicinal chemistry, to
purification of peptides and other biomolecules, to protein enrichment
in proteomics. (ChemDiv) is a global chemistry-driven contract research
organization focused on the delivery of new scientific innovation, products
and services that meet the drug discovery needs of its partners.

The association can be by adsorption or chemisorption (as is the case for solid , heterogeneous catalysts) or by complexation or coordination (as is the case for homogeneous catalysts , including enzymes).

New to science in the past decade, fluorous
affinity tags act as molecular handles for purification without
affecting any other aspect of the chemistry. After placing a fluorous
tag on an oligonucleotide by means of traditional solid-phase
techniques, the tagged material can be easily separated from
impurities. Yeske, CEO of
