Calcium Rubies: A Family of Red-Emitting Functionalizable Indicators

We designed Calcium Rubies, a family of functionalizable BAPTA-based red-fluorescent calcium (Ca2+) indicators as new tools for biological Ca2+ imaging.

NMR Crystallography:Disentangling Crystallographic Inequivalence and Crystallographic Forms of L-Arginine by One- and Two-Dimensional Solid-State NMR Spectroscopy

Overlapping 13C or 15N solid-state NMR spectra from crystallographically different forms of L-arginine hydrochloride can be separated by exploiting differential proton T1 relaxation in conjunction with cross polarization.

Mapping molecules inside cells is a contemporary challenge that requires both high sensitivity and sub-micrometric resolution. IR-spectroscopy is valuable for chemical imaging.
