Recombinant protein purification Service

Detai Biologics can provides a variety of protein purification services,including:recombinant protein purification , Natural protein purification. Such us antibody,enzyme,growth factors,Membrane protein.

The goal of protein purification is to obtain high purity and high activity protein under high efficiency and high yield. The target protein is different, protein research purpose,Protein source, These factors lead to the selection of protein purification methods should also be different. We will analyze the physical and chemical characteristics and biological characteristics of the target protein (such as Solubility, charge, hydrophobicity,Molecular), According to the analysis results, choose the most suitable method.

We have advanced AKTA purification system and Ion column Molecular sieve, hydrophobic column and affinity column. Professional protein purification team, Using gel filtration, ion column, molecular sieve, affinity column, electrophoresis, covalent chromatography and other protein purification techniques for you to develop the most suitable protein purification program.

Protein purification service advantages

Protein purification serviceAdvanced AKTA purification system, suitable for purification of proteins from different sources. Multiple protein purification system (Affinity chromatography, ion exchange, molecular sieve, hydrophobic chromatography, HPLC) . We provide comprehensive protein purification analysis report and protein QC report.

Protein purification methods

purification methods content
Affinity chromatography Separated with the specificity between protein and ligand
Ion exchange chromatography The ion exchange agent and protein binding charge, By changing PH or increasing the ionic strength of the buffer elution of target protein
Gel filter chromatography Proteins are separated by protein molecularand shape
Hydrophobic chromatography Purified by reversible effect of protein and Hydrophobic ligand
HPLC High separation efficiency, high sensitivity, fast analysis

In general, the protein that we delivered are stored in the Tris buffer. If yuo need other requirement, we cna provide otners buffer or freeze drying service.
