Protein Gel Electrophoresis | Thermo Fisher Scientific

This page provides an overview of Invitrogen and Thermo Scientific protein gel electrophoresis products. Protein gel electrophoresis is a fundamental laboratory technique to separate and analyze proteins based on size and charge as they migrate through a gel matrix under an electric field. By resolving protein samples on protein gels, researchers can assess protein expression, purity, molecular weight, and integrity, making protein electrophoresis essential for protein biology labs.

Buffers for SDS-, Native- PAGE electrophoresis, and IEF.

Protein ladders

Prestained, unstained and western blot ladders.

Protein stains

Stains for every application from quick visualization to high-sensitivity applications.

Electrophoresis chamber systems

Perform multiple types of gel runs using mini and midi gel tank systems and gel transfers in some chambers using optional blot modules.

Tetra electrophoresis cores

Run Invitrogen Precast Protein Gels in your Bio-Rad Mini-PROTEAN Tetra Cell tank. Easy to assemble and use.

Power supplies

A range of powerful, easy-to-use electrophoresis power supplies for gel electrophoresis, western transfer, and more demanding applications.

Tools to improve quality and accuracy of your protein analysis workflow

Total protein normalization for gel or blots

Use the Invitrogen No-Stain Protein Labeling Reagent for total protein normalization to help improve the accuracy of your quantitative western blotting data. The No-Stain Protein Labeling Reagent provides a flexible, accurate, and rapid method to visualize and normalize proteins in a gel or on a membrane (post-transfer).

Protein sample preparation

Generate quality protein samples for separation with optimized tissue lysis, cell lysis, and sub-cell fractionation buffers. Protect samples with easy and effective protease and phosphatase inhibitors, excellent for the protection of proteins during extraction or lysate preparation.
