Custom Protein Purification Services

We have a world-class reputation for purifying proteins and go beyond this to provide custom solutions for our customers including many upstream and downstream activities that add exceptional value for our clients. Don't see what you need listed below? The question we hear most at mtibio is, "Can you do this?" Most of the time, the answer is yes. If you want to find out if we can help you face your research challenges, please feel free to contact us at any time.


Assay development to direct purification of fully active enzymes from both recombinant and native sources.

Traditional Purification Methodology

Many custom proteins must be expressed without purification tags for proper function.  We develop protocols using tag-independent “traditional” methodologies.

Protein Purification from Native Tissues

Native source proteins require traditional protein purification methods and generally require enzymology to select the most active fractions and direct the purification.

Molecular Biology

cDNA cloning from special and exotic species has become an increasingly popular request.  Much of this has been driven by the requirements to functionally verify a target in toxicology studies.

Endotoxin Exclusion

Our process of producing proteins from mammalian cells such as antibodies and Fc-fusions involves the use of dedicated purification equipment that is validated at every stage of the purification.

Endotoxin Removal

We have developed special processes to remove endotoxin from E. coli sourced protein including a number of active enzymes.
