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.
RUO
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.
Animal-free
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.
GMP
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.
Innovative engineered proteins
Wnt surrogate-FC fusion
Gibco Wnt Surrogate-Fc Fusion Protein has been engineered for increased solubility and potency, while activating similar Wnt signaling pathways as most recombinant Wnt3a proteins or Wnt-conditioned media.
Heat-stable technology
Gibco and PeproTech heat-stable recombinant growth factors have been engineered for greater stability in cell culture conditions. Get exceptional performance and retain bioactivity without artificially high concentrations.
Recombinant proteins for modulating cell growth and differentiation
Recombinant proteins for SARS-CoV-2 research

 | SELE SELE (E-Selectin) is found on cytokine-stimulated endothelial cells and is thought to be responsible for the accumulation of blood leukocytes at sites of inflammation by mediating the adhesion of cells to the vascular lining. This adhesion molecule participates in the interaction between leukocytes and the endothelium and appears to be involved in the pathogenesis of atherosclerosis. |  | CDH1 CDH1 (E-Cadherin) is one of the best-understood cadherin proteins. In addition to its role in cell adhesion, E-cadherin is involved in transmitting chemical signals within cells, controlling cell movement, and regulating the activity of certain genes. Loss of function is thought to contribute to progression in cancer by increasing proliferation, invasion, and/or metastasis. | |||
 | AMICA1 AMICA1 (JAML) is an adhesion molecule that may function in the migration of leukocytes through epithelial and endothelial tissues. Expressed at the plasma membrane of polymorphonuclear leukocytes, it mediates adhesive interactions with CXADR, a protein of the junctional complex of epithelial cells. AMICA1 enhances myeloid leukemia cell adhesion to endothelial cells. |  | ICAM1 ICAM1 (CD54) is an endothelial- and leukocyte-associated glycoprotein known for its importance in stabilizing cell-cell interactions and facilitating leukocyte endothelial transmigration. It binds to integrins of type CD11a/CD18, or CD11b/CD18 and is also exploited by Rhinovirus as a receptor. | |||
 | L1CAM (CD171) L1CAM (CD171) is an axonal glycoprotein belonging to the immunoglobulin supergene family. This cell adhesion molecule plays an important role in nervous system development, including neuronal differentiation, migration, and the formation of myelin and synapses. |  | CDH2 CDH2 (N-Cadherin) is a classical cadherin from the cadherin superfamily as it is a calcium dependent cell-cell adhesion glycoprotein comprises five extracellular repeats, a transmembrane region and a highly conserved cytoplasmic tail. CDH2 functions during gastrulation and is required for establishment of left-right asymmetry. At certain central nervous system synapses, presynaptic to postsynaptic adhesion is mediated at least in part by this protein. |
