Protocol for selection of an ion exchanger: Determining the pI of a protein using isoelectric focusing. The choice of whether to use an anion or a cation exchanger should be based on knowledge of the stability of the protein, and the binding properties of the target protein and other molecules present. - [Read Selection of an Ion Exchanger Protocol]
Protocol for selection of an ion exchanger: Determining the pI of a protein using the titration curve method. The choice of whether to use an anion or a cation exchanger should be based on knowledge of the stability of the protein, and the binding properties of the target protein and other molecules present in the sample. - [Read Selection of an Ion Exchanger Protocol II]
Protocol for selection of an ion exchanger: Determining the pI of a protein using the test tube method. The choice of whether to use an anion or a cation exchanger should be based on knowledge of the stability of the protein, and the binding properties of the target protein and other molecules present in the sample. - [Read Selection of an Ion Exchanger Protocol III]
Protocol for selection of an ion exchanger: Determining the pI of a protein using the Trial-and-Error method. The choice of whether to use an anion or a cation exchanger should be based on knowledge of the stability of the protein, and the binding properties of the target protein and other molecules present in the sample. - [Read Selection of an Ion Exchanger Protocol IV]
Protocol for separating proteins using ion-exchange chromatography. Protocol details the practical considerations of an ion-exchange chromatography (IEC) experiment. The choice of what type of ion exchanger to use, as well as the composition of the buffers used in this experiment, should be determined prior to beginning this protocol. - [Read Separating Proteins Using Ion-Exchange Chromatography Protocol]
