Recombinant proteins from trusted brands

Whether conducting basic research or developing next-generation engineered cell therapies, you need to be able to rely on the quality and integrity of the recombinant proteins used in your experiments. As a premiere recombinant protein supplier and manufacturer, Thermo Fisher Scientific offers a large section of high-quality Invitrogen and Gibco brand proteins, including Gibco PeproTech proteins to meet these needs.

Explore recombinant proteins by intended use

Thermo Fisher Scientific recombinant proteins are produced and tested to rigorous standards that vary depending on the product grade/intended use.

All research-grade recombinant proteins are produced in cell culture (mammalian, bacterial, yeast, insect). Every batch is tested for identity, purity, and biological activity using appropriate assays. PeproTech and other Gibco recombinant proteins are designed and tested for cell culture modulation whereas Invitrogen proteins are ideal for use in biochemical and cell analysis applications.

Search RUO recombinant proteins

Animal-free recombinant proteins are manufactured using only chemically defined, animal-origin free (AOF) materials. Animal-free recombinant proteins are ideal for use in animal studies as well as 3D cell culture models, as they mitigate the risk of spurious results from unknown etiological agents that may exist in animal-derived proteins.

Gibco PeproGMP recombinant proteins are manufactured for use as ancillary materials in clinical manufacturing. Considerations such as quality control, documentation, and technical support are center to your bench-to-clinic success. PeproGMP recombinant proteins are designed to help you deliver results quickly.
