High-throughput multiplexed competitive immunoassay for pollutants sensing in water
Desmet, Cloé,Blum, Loic J.,Marquette, Christophe A.
, p. 10267 - 10276 (2012)
The present study described the development and evaluation of a new fully automated multiplex competitive immunoassay enabling the simultaneous detection of five water pollutants (okadaic acid (OA), 2-chloro-4-ethylamino-6- isopropylamino-1,3,5-triazine (atrazine), 2.4-dichlorophenoxyacetic acid (2,4-D), 2,4,6-trinitrotoluene (TNT), and 1,3,5-trinitroperhydro-1,3,5-triazine (RDX)). The technology is taking advantage of an optical-clear pressure-sensitive adhesive on which biomolecules can be immobilized and that can be integrated within a classical 96-well format. The optimization of the microarray composition and cross-reaction was performed using an original approach where probe molecules (haptens) were conjugated to different carriers such as protein (bovine serum albumin or ovalbumin), amino-functionalized latex beads, or dextran polymer and arrayed at the surface of the adhesive. A total of 17 different probes were then arrayed together with controls on the adhesive surface and screened toward their specific reactivity and cross-reactivity. Once optimized, the complete setup was used for the detection of the five target molecules (less than 3 h for 96 samples). Limits of detection of 0.02, 0.01, 0.01, 100, and 0.02 μg L-1 were found for OA, atrazine, 2,4-D, TNT, and RDX, respectively. The proof of concept of the multiplex competitive detection (semiquantitative or qualitative) of the five pollutants was also demonstrated on 16 spiked samples.

Paragraph 0283-0286, (2016/12/01)
The present technology provides polycyclic epoxides of Formula I, compositions comprising such expoxides and methods of using such epoxides. In particular, these compounds are useful for inhibiting cancer cell proliferation and tumor angiogenesis or treating ovarian, breast, prostate, liver, pancreatic, and colon cancers, as well as leukemia.

supporting information; experimental part, p. 1153 - 1155 (2010/06/17)
We have synthesized an analog of dehydroepiandrosterone (DHEA, 1) containing both a benzophenone (BP) and a biotin (Bt) group (DHEA-BP-Bt, 8). Compound 8 was prepared by functionalization on C-17 of 1. Biocytin was reacted with 4-benzoylbenzoic acid and t
