Abstract
Potassium tris(oxalato)chromate(III) trihydrate (chromium ixalate) has been shown to be a more useful broadening agent than potassium ferricyanide for the spin label 2,2,6,6-tetramethylpiperidine-N-oxyl-4-amine (Tempamine) in thylakoid suspensions. Our data show that chromium oxalate is less permeable than ferricyanide, does not inhibit thylakoid electron transport or photophosphorylation, and is not photoreduced by thylakoids.
摘要
三水合三草酸根合铬(III)酸钾（草酸铬）已被证明，对于类囊体悬浮液中的自旋标记物2,2,6,6-四甲基哌啶-N-氧基-4-胺（Tempamine）而言，它是一种比铁氰化钾更有效的展宽剂。我们的数据表明，草酸铬的渗透性比铁氰化钾低，不会抑制类囊体电子传递或光合磷酸化，并且不会被类囊体光还原。
