Biparatopic binding of ISB 1442 to CD38 in trans enables increased cell antibody density and increased avidity by Jeremy Loyau, Thierry Monney, Marco Montefiori, Fedir Bokhovchuk, Jeremy Streuli, Matthew Blackburn, Arnaud Goepfert, Lydia N. Caro, Samitabh Chakraborti, Stefania De Angelis, Camille Grandclément, Stanislas Blein, M. Lamine Mbow, Ankita Srivastava, Mario Perro, Stefano Sammicheli, Eugene A. Zhukovsky, Michael Dyson, Cyrille Dreyfus

“…The predicted antibody-antigen stoichiometries at different CD38 surface densities were experimentally validated by surface plasmon resonance and cell binding assays. The specific design and structural features of ISB 1442 enable: 1) enhanced trans binding to adjacent CD38 molecules to increase Fc density at the cancer cell surface; 2) prevention of avid cis binding to monomeric CD38 to minimize blockade by soluble shed CD38; and 3) greater binding avidity, with a slower off-rate at high CD38 density, for increased specificity. …”

Radiation-Induced Correlation between Molecules Nearby Metallic Antenna Array by Yoshiki Osaka, Nobuhiko Yokoshi, Hajime Ishihara

“…The most distinguishing feature of our work is to show that the shift is largely enhanced even when the individual molecules couple with localized surface plasmons near the different antennas. Specifically, we first consider the case that two sets of dimeric gold blocks with a spacing of a few nanometers are arranged and reveal that the intensity and spectral peak of the optical absorption strongly depend on the position of the molecules. …”
