Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Bis(2,5-dioxopyrrolidin-1-yl) O,O’-ethane-1,2-diyl disuccinate, is researched, Molecular C18H20N2O12, CAS is 70539-42-3, about Chemical crosslinking approach to reveal spatial arrangement of subunits in PS II oxygen-evolving core complexes.Quality Control of Bis(2,5-dioxopyrrolidin-1-yl) O,O’-ethane-1,2-diyl disuccinate.
The spatial arrangement of subunits of photosystem II O2-evolving core complexes was analyzed by crosslinking the core complexes with bifunctional crosslinking agent [such as 1-ethyl-3-[3-(dimethylamino)propyl]carbodiimide, di-Me hexanedioate, N,N- dicyclohexylcarbodiimide, etc.] at room temperature for 10 min, terminating with 10% glycine solution, centrifuging, suspending in SMN buffer (composed of sucrose 0.4, NaCl 10, and Mes-NaOH 50 mM, its pH 6.0), and detecting via SDS-PAGE.
Compound(70539-42-3)Quality Control of Bis(2,5-dioxopyrrolidin-1-yl) O,O’-ethane-1,2-diyl disuccinate received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(Bis(2,5-dioxopyrrolidin-1-yl) O,O’-ethane-1,2-diyl disuccinate), if you are interested, you can check out my other related articles.
