Protein Expression & Purification

Scalable Solutions for Efficient Protein Production

Molecular Express provides tailored protein expression and purification solutions, with capabilities for E. coli expressions from small (1–4 liters) to large (up to 25 liters) scales. Using animal product-free media to generate high yields of contaminant-free biopharmaceuticals with batch-to-batch consistency.

Our team specializes in purifying challenging hydrophobic proteins, using advanced techniques to meet specific purity requirements.

• Immobilized-Metal Affinity Chromatography (IMAC): Ideal for His-tagged proteins, providing high specificity and yield.
• Ion Exchange Chromatography: Efficient separation based on the protein's charge, optimizing purity levels.
• Size Exclusion Chromatography: A powerful method for separating proteins based on size, perfect for removing aggregates.
• High-Performance Liquid Chromatography (HPLC): Ensures the highest purity and concentration of your target proteins.
