Our isoelectric focusing (IEF) horizontal gels are made by Serva Electrophoresis. These isoelectric focusing (IEF) gels are for use for determining isoelectric points of proteins. The IEF gels come in both mini-gel formats for vertical gel boxes and as horizonal gel IEF. The horizonal IEF gels are used for analytical quality control IEF where very minor variations in isoelectric points are need to be screened for. They offer higher sample throughput, two different thicknesses for great resolution and are available in a variety of pH gradients included blank gels. A pH gradient in a blank gel is easily made by electrophoresing the ampholyte of choice into the gel along with the sample.
