Protein Expression, Purification & Analysis

Protein Expression

Visit our Protein Expression page to find the latest information on cell-free expression products, including the New S30 T7 High Yield Protein Expression System:

• Eukaryotic Cell-Free Systems
• Prokaryotic Cell-Free Systems
• Prokaryotic Cell-Based Systems
• Expression Vectors

Protein Purification

Visit our protein purification page to find out how you can improve isolation of  polyhistidine, HaloTag^®, or GST tagged proteins using manual or automated systems.

Protein Interactions

Quickly identify protein:DNA interactions with the HaloCHIP™ system--the fast alternative to ChIP assays.

For protein:protein interactions, try the GST-based MagneGST™ Pulldown Assay or the CheckMate™ Mammalian Two-Hybrid System.

Mass Spectrometry Analysis

Enhance solubilization and denaturation of proteins with Trypsin Gold and ProteasMAX™ Surfactant: get efficient in-solution digestion, and improve recovery of peptides from in-gel digestions.

Imaging, Protein Detection & Labeling

HaloTag® Technology offers a powerful alternative for protein functional analysis. The multiple interchangeable fluorophores allow use of a single genetic construct for all your applications, including in vivo localization and protein trafficking.

For Western blots and other immunoblotting applications, our easy-to-use colorimetric and fluorometric protein labeling systems allow you to detect proteins without the use of radioactive labels.
