Abstract
Libraries encoded with electrophoric tags present a unique challenge with
respect to library quality control and characterization. Libraries are
prepared on Tentagel resin in 200-fold redundancy wherein each resin
particle contains one compound per one tag set. The amount of compound
present on the bead is ca. 200-500 pmole while tag levels are estimated at
0.5-1 pmol/bead. Several quality control protocols have been developed in
order to accurately estimate bead yield and purity for the entire library,
ensure high tag fidelity, and to determine the overall performance of
individual synthons. This review provides a unique, collective portrait of
Pharmacopeia's approach in assessing the quality of libraries prepared
using its molecular encoding technology.
