Focus Gels

FocusGels are available with different pH gradients, with or without sample slots. FocusGels are 0.65 mm thin polyacrylamide gels with T = 5 % gel concentration and C = 3 % crosslinking for isoelectric focusing, which have been polymerized under special conditions, in order to obtain an optimal matrix suitable for IEF.
Catalysts as well as other non toxic and non polymerized compounds have been removed from the matrix. Therefore, FocusGels are not toxic. The gels contain a special carrier ampholyte cocktail to achieve an optimal pH gradient. No electrode solutions and electrode stripes are used; the electrodes are placed directly on the gel surface. FocusGels 24S contain 24 pre-polymerized sample wells for easy application of up to 25 µl protein solution close to the anodal or cathodal side. The other FocusGel types do not contain sample wells. Here samples can be applied employing various sample applicators.
