Opis ogólny

Sodium cacodylate trihydrate is a biological buffer. Its crystals have been analyzed by single-crystal X-ray diffraction studies. Studies suggested its crystals exhibited two phases, viz. penta-μ-aqua-disodium(I) bis(dimethylarsenate), {[Na2(H2O)5](C2H6AsO2)2}n and di-μ-aqua-bis[triaquasodium(I)] bis(dimethylarsenate), [Na2(H2O)8](C2H6AsO2)2.

Zastosowanie

Sodium cacodylate trihydrate may be employed as buffer to maintain pH 7.4 in electron microscopic studies. It may be used to compose cacodylate buffer for use in electron microscopic studies.

Enhanced expression of tenascin-C (TN-C) at the invasive edges of glioblastoma multiforme in close association with vascular sprouts, suggests a role for TN-C in microvascular cell migration. To test this hypothesis, we studied the migration of endothelial cells in vitro.

Crystals from commercial samples of sodium cacodylate trihydrate, NaO2As(CH3)2 x 3 H2O, were analyzed by single-crystal X-ray diffraction and two phases were identified, viz. penta-mu-aqua-disodium(I) bis(dimethylarsenate), {[Na2(H2O)5](C2H6AsO2)2}n, (I), and di-mu-aqua-bis[triaquasodium(I)] bis(dimethylarsenate), [Na2(H2O)8](C2H6AsO2)2, (II).

While the subcellular organisation of mitochondria is likely to influence many aspects of cell physiology, its molecular control is poorly understood. Here, we have investigated the role of the retrograde motor protein complex, dynein-dynactin, in mitochondrial localisation and morphology. Disruption
