PARcaEDX

PAR-Ca spheres formed after incubation of the polysaccharide poly (ADP ribose) with calcium ions. The EDX spectrum shows peaks for PAR-bound calcium, the phosphorus peak is derived from the pyrophosphate groups of PAR. The SAED shows the amorphous nature of these spheres (Karin Müller – CAIC; Prof. Melinda Duer – Dept. of Chemistry, Cambridge; Prof. Cathy Shanahan – King’s College London).
