FAQ - Frequently Asked Questions about Recombinant Protein Production

Which expression systems do you use for recombinant protein manufacturing?

We provide expert consultation to select the right system. For complex proteins requiring human-like glycosylation, we use mammalian systems (HEK, CHO). For simpler proteins, E. coli is a cost-effective alternative.

What is the typical timeline for protein production?

From gene synthesis to purified protein, our timeline is typically 6-12 weeks, depending on complexity and scale. We also offer express services for urgent projects.

Do you offer protein engineering and modifications?

Yes, we can customize your proteins with various tags, conjugates, or modifications – from His-tags to specific mutations.

Is your protein manufacturing ISO 13485 certified?

Yes. As a specialized contract manufacturer in Germany, our entire protein production process is ISO 13485:2016 certified. This guarantees full traceability and documentation – making our proteins ideally suited as critical raw materials for IVDR-compliant diagnostics.

Can your proteins be used for IVDR diagnostic kits?

Yes. We produce under strict ISO 13485 guidelines and provide all necessary documentation (CoAs, production protocols) to support your technical file and regulatory compliance under IVDR.
