Choose SDS-PAGE and native-PAGE gels, convert to TGX Precast Gels, or choose specialized gel chemistries including stain-free. Refer to the list of compatible reagents for more information. Typically, a low concentration of imidazole is added to both binding and wash buffers to interfere with the weak binding of other proteins and to elute any proteins that weakly bind. Most importantly, from a range of sample sources into minimal elution volumes (i.e., 6 l). Thank you to the thousands of users who visited our guide design tool over the past five years. Salting out proteins requires prior knowledge of the proteins solubility. Available in Protein A and Protein G. Antibodies.
