Leaf proteins from 14 barley cultivars (Hordeum vulgare) were analyzed by two-dimensional electrophoresis with immobilized pH gradients (IPG 4-7 and IPG 6-10) in the first dimension. Highly reproducible two-dimensional patterns were obtained, owing to constant spot positions along the isoelectric focusing axis. A number of variety-specific protein spots(More)
Cytodifferentiation in many melanocytic cells is regulated through the adenylate cyclase-cAMP pathway. To analyse the molecular changes associated with this process we have compared the proteins produced by two closely related cell lines which, though derived from a single cell line, respond very differently to modulation of this signalling pathway. The(More)
Most of the problems connected with the use of the Immobiline chemicals (a set of six, non-amphoteric, acrylamido buffers having pK values in the pH 3.5-9.5 interval) can be attributed to the alkaline species (with pK values 6.2, 7.0, 8.5 and 9.3). These compounds, to varying degrees are subjected to two degradation pathways: (a) hydrolysis of the amido(More)
