Protein Purification

The process that isolates one or a few proteins from cells or tissues is protein purification, which is vital for the characterization of the structure, function, and interaction of proteins. Protein purification generally based on the distinction between protein size, properties, binding affinity, and biological activities. Creative Biostructure has developed an advanced purification platform that use various purification strategies to provide either small amount of protein for research purposes or manufacturing large quantity of proteins for commercial uses. We are confident to efficiently deliver solutions for high purity protein purification and constantly develop and improve the purification protocols. The available methods to purify proteins range from simple precipitation to sophisticated chromatographic and affinity techniques.

Depending on the project requirements and the nature of the proteins, purification protocols can be either de-novo designed by us or obtained from customers or literature. Our purification methods include affinity chromatography with various tags, protein-specific chromatography, etc. The final goal is to accomplish a homogeneous and biologically active protein preparation that is critical for crystallization, protein-drug assays and other related studies.

Protein purification protocols

  • De-novo purification protocols
  • Existing protocols from customers or published sources
  • Optimized protocols for various expression systems

Key features
