Custom Protein Expression Service

We offer different analytical methods according to your needs. Always included is SDS-PAGE and determination of protein concentration. Very often we do Western blot analysis. If needed, we can determine the oligomeric state by analytical size exclusion chromatography (SEC) or native PAGE. Mass spectroscopic analysis is also offered on request to determine for example the modification of proteins. Other assays such as ELISA and activity assays are available.

The concentration is mostly between 0.1 and 2 mg/ml but can be adjusted according to your needs. The concentration will be determined by either BCA, adsorption at 280nm or densitometric determination after Coomassie staining.

We are working on recombinant proteins for more than 20 years and we have successfully produced more than 3000 different proteins so far.

Our expertise covers a wide range of protein classes, including soluble enzymes and secreted proteins such as antibodies and their derivatives, as well as more complex variants such as nuclear and membrane proteins. To ensure the ultimate success for your target protein, we identify and utilize the most appropriate expression system and backbones and screen different variants in small scale.

Yes, in most cases we use cleavable tag sequences. But cleavage efficiency can be influenced by the target protein and has to be tested.

Yes, we offer various recombinant proteins off the shelf. Have a look at our continuously growing ➥ catalog.

Yes, at Trenzyme, we specialize in the production of high-quality recombinant human proteins.

Our custom protein expression service utilizes a range of advanced expression systems, including mammalian cells, insect cells, yeast, and E. coli, to ensure optimal yield, purity, and functionality. Whether you require small-scale research-grade proteins or large-scale production, we tailor our approach to meet your specific project needs.

With our extensive expertise and state-of-the-art technologies, we guarantee high reproducibility, scalability, and regulatory compliance. Let us support your research with reliable and fully customized recombinant human proteins!
