Recombinant Proteins Support
Explore our “Getting Started” and “Troubleshooting” sections for solutions to top inquiries and common problems. Browse through our "Guides and Tools" section to access resources and documentation regarding use of recombinant proteins (including Gibco PeproTech recombinant proteins) for various applications.
Getting Started
- How do I store my lyophilized recombinant protein?
- How should I reconstitute Gibco recombinant proteins and Gibco PeproTech recombinant proteins?
- What are the growth factors or cytokines used in neural stem cell (NSC) culture?
- What are the major differences between the recombinant proteins produced in different expression systems?
- What is the relationship between the specific activity expressed as an ED50 and as units/mg?
Troubleshooting
- It looks like the recombinant protein vial I received from you is empty. Is this normal?
- Why is my recombinant protein not soluble?
- Why does my recombinant protein not have the activity claimed by the product materials?
- Why does my recombinant protein not show activity in my own experiment?
- Why is there no ED50 information available for some of the cytokines/chemokines?

Custom Services
Looking for bulk or custom production of your recombinant protein? Once you have determined your requirements, please download the custom service requirements form, complete, and submit it.
Custom Antibody Production Service
Custom antibody production services include competitively priced packages and purification options for antibody production, all supported by online tools for peptide design and project tracking. We provide complete support for all types and steps of antibody production—from peptide design, synthesis, and carrier protein conjugation to animal immunization, serum collection, or hybridoma fusion, titer analysis, and final antibody purification. We also immunize with recombinant proteins or protein fragments provided by you (or expressed and purified in our lab using cDNAs from our extensive in-house genomics library) to generate antibodies in rabbits, chickens, goats, guinea pigs, mice, or rats.
Custom Protein Labeling Service
Our custom protein labeling service combines years of conjugation expertise with a wide selection of labels, including fluorescent dyes, phycobiliproteins, and enzymes, along with a choice of labeling chemistries. We provide conjugation services for both research and commercial use. Once you have determined your requirements, please download the custom labeling quote form, complete it, and email it to the address on the form. For questions, please contact us at customorders@thermofisher.com.
