Protein purification is a crucial step in biotechnology, pharmaceuticals, and academic research, ensuring the isolation of high-quality proteins for various applications. Protein purification services provide tailored solutions to meet diverse needs, offering expertise, advanced technologies, and scalable workflows to achieve optimal purity and yield.
Customized Purification Strategies
Different proteins require specific purification strategies depending on their properties, intended use, and production scale. Protein purification services employ a range of techniques to ensure high-quality results:
- Affinity Chromatography: A widely used method that leverages specific interactions between a protein and a ligand attached to a resin, enabling highly selective purification. Common affinity tags include His-tag, GST, and FLAG-tag.
- Ion-Exchange Chromatography: Separates proteins based on their charge by utilizing cation or anion exchange resins, offering high resolution and scalability.
- Size-Exclusion Chromatography: Also known as gel filtration, this technique isolates proteins based on molecular size, effectively removing aggregates and contaminants.
- Hydrophobic Interaction Chromatography: Utilizes hydrophobic properties to separate proteins under controlled conditions, maintaining protein stability.
- Mixed-Mode Chromatography: Combines different interaction principles to enhance selectivity and efficiency, particularly for challenging purification tasks.
