Introduction
 |
GeneCopoeia provides a range of pre-made recombinant proteins for various applications including Western Blot, ELISA, antibody development and more. Our protein production facility uses host-cell expression systems, including E.coli and mammalian cells systems, and cell-free expression systems. We also use a variety of unique fusion tags to increase protein expression, solubility and yield. |

Frequently Asked Questions
Answer: We offer pre-made recombinant protein products. Our expression facility uses host cell systems such as bacteria, mammalian cell lines (HEK293 and HEK293T cells), yeast, insect (Sf9 cells) and cell-free expression systems.
Answer: Yes. GeneCopoeia recombinant proteins are produced serum-free. In addition, most of GeneCopoeia’s proteins are carrier-free (except for proteinase products). They do not contain BSA, and therefore can be used directly in SDS PAGE gels and western blots.
Answer: Yes. Removing a tag can be as easy as choosing one. The removal of some small molecular weight tags, such as His and Flag, is often not necessary.
Answer: GeneCopoeia uses either affinity purification or ion exchange chromatography for protein purification. We will determine the best purification strategy based on your needs and the protein’s properties.
Answer: GeneCopoeia recombinant proteins have not been functionally tested in vivo. Therefore, GeneCopoeia cannot guarantee that all proteins are fully functional in all assays, including those for in vivo applications.
Answer: GeneCopoeia recombinant proteins generally remain stable for 1-3 years under appropriate storage conditions. We recommend aliquotting the protein solution and storing the tubes at -80℃. Avoid repeated freeze-thaw cycles.
