Peculiar features of application of pH gradients formed in borate buffer with a polyhydroxy compound for separation of proteins in a free-flow electrophoretic apparatus

The use of pH gradients in borate buffer with a polyhydroxy compound for separation of proteins in a free-flow electrophoretic apparatus is outlined. The composition of the pH gradients, the free-flow apparatus design and its operation, and the main causes of failures in the protein separation are considered.

Photochemical reduction of organic electron acceptors in aqueous solutions

Conclusions The formation of OH radicals in the photoreduction of aqueous solutions of anthraquinonesulfonic acid as the result of electron transfer from water (OH^–) to a triplet molecule has been demonstrated.Translated from Izvestiya Akademii Nauk, Seriya Khimicheskaya, No. 11, pp. 2615–2617, November, 1969.
