Bio-Rad Protean IEF Cell

This used Bio-Rad Protean IEF Cell is a compact isoelectric focusing system used in the first dimension of two dimensional gel electrophoresis workflows. It is designed to run IPG strips for protein separation based on isoelectric point, providing precise voltage control and temperature regulation to support reproducible focusing runs. The unit has seen prior lab use and continues to function as intended for standard IEF protocols. The system accommodates multiple IPG strip lengths and includes a focusing tray with individual sample wells, allowing labs to run several strips simultaneously under controlled conditions. Its built in power supply and program presets make it straightforward to set up voltage gradients for various protein classes, which supports high resolution separation ahead of SDS-PAGE second dimension runs. This reliability has made it a familiar fixture in proteomics labs working with complex protein mixtures. Researchers performing 2D gel electrophoresis for proteomic profiling, biomarker discovery, or quality control of protein preparations will find this IEF cell a practical addition to their workflow. It is well suited to academic, pharmaceutical, and biotech labs that need dedicated isoelectric focusing capability alongside their existing electrophoresis equipment. The unit is offered as a functional used system ready to support ongoing protein separation work.
