Protein Purification

Fina BioSolutions protein purification services help biotech companies move from discovery to early clinical trials. We specialize in developing protein purification/downstream processing protocols for laboratory-scale and process scale-up.

We can scale from milligrams to multi-gram production.

We offer affordable recombinant protein production for laboratory and preclinical projects. Starting from the amino acid sequence of your protein of interest we can deliver purified protein, either tagged or unmodified.  We can provide assistance with purification and scale-up issues. Our expert scientists have extensive experience with bacterial and expression systems.

We can step in at any stage of your protein production and help you with scale up or purification issues. Our experts have extensive experience with expression of difficult proteins including improving the solubility of expressed protein and inclusion body refolding.
