Optimised and Efficient Protein Sample Preparation

Protein extraction, purification, and cleanup products.

Why choose Thermo Scientific™ Protein Sample Preparation

Protein Extraction Reagents and Kits

We offer a full range of optimised protein extraction products designed to maximize protein yield and activity. The gentle formulations have been validated with multiple sample types to eliminate mechanical disruption and preserve protein activity.

Protein Cleanup

Our easy-to-handle devices offer high performance for secure sample processing and protein recovery, removing unwanted small molecules and salts, to help maintain protein integrity and purity for subsequent downstream applications.

Protein Purification

Our high-performance resins and magnetic beads offer a broad range of formats for ion exchange and affinity-based isolation of proteins and antibodies in microgram to kilogram quantities.

Protein Sample Preparation

Extract. Clean up. Purify.

Our convenient devices and high-performance affinity resins and magnetic beads enable maximum yield for the purification, enrichment, and cleanup of proteins and antibodies for downstream applications.

Protein sample preparation is a process which includes protein extraction through cell disruption, protein preservation using protease and phosphatase inhibitors, protein isolation and purification, buffer clean-up through dialysis, desalting and concentration, and quantitation with assay methods that may use fluorescent or colorimetric detection.

Protein preparation is an important step before proteomics workflows involving mass spectrometry or gel electrophoresis. These products are optimized for a wide range of tissue and cell types and are compatible with a broad range of protein purification resins and formats.

Desalt, buffer exchange, remove contaminants, and concentrate proteins with our secure and efficient devices and resins.
