MedChemExpress (MCE) provides a range of cytokines and growth factors, including interleukins, chemokines, interferons, transforming growth factors, fibroblast growth factors, as well as the cytokine receptor family.

Covering a series of immune checkpoint molecules, including PD-1/PD-L1, CTLA-4, TIM-3, OX40, TIGIT, and novel immune checkpoint proteins such as butyrophilins (BTNs).

Covering popular targets, including BCMA, CD19, MSLN, HER2, MUC1, CD22, ROR1, and providing labeled target antigens, such as fluorescently labeled and biotin-labeled, to support CAR-T research and development.

CD molecules function as cell adhesion molecules, cytokine receptors, ion channels, or nutrient transport proteins, playing various roles in immune system function. CD molecules are commonly used as cell markers for immune antigen recognition.

The binding activity between the Fc fragment of antibodies and receptors affects the efficacy of antibody drugs. MedChemExpress (MCE) offers a range of high-quality recombinant Fc receptor proteins for antibody drug modification and evaluation, facilitating the development of antibody drugs.

Receptor proteins include enzyme-linked receptors, cell adhesion molecules, G protein-coupled receptors, nuclear receptors, pattern recognition receptors, Notch, and other receptor families.

Most biological processes in organisms are regulated by enzymes. MedChemExpress (MCE) provides a variety of enzyme-related proteins, including various families of enzymes and inhibitors, such as MMPs, proteases, CDKs, phosphatases, protease inhibitors, kinase inhibitors, and CDK inhibitors.

MedChemExpress (MCE) has developed a series of high-quality recombinant proteins, including C3, C5, MASP, complement regulatory factors, etc., to support research on the complement system mechanism and related diseases.

Ubiquitination regulates various cellular processes, including cell division and differentiation, responses to environmental stress, cell differentiation, immune reactions, DNA repair, and apoptosis.

MedChemExpress (MCE) provides a variety of recombinant viral proteins, including influenza viruses, coronaviruses, HIV, hepatitis viruses, and more, to support research on viral infections.

MedChemExpress (MCE) has developed nearly a thousand recombinant biotinylated and Avi-Tag proteins, which can be used in protein purification, protein-protein interactions, detection, screening, and other research applications.

Fluorescent labeling is a versatile tool for studying molecular interactions, tracking protein movement, and probing protein biological functions.

MedChemExpress (MCE) GMP recombinant proteins are manufactured under specific guidelines to ensure product quality and consistency. Each lot of our GMP-grade recombinant proteins undergoes rigorous QC testing tests.

Animal-free recombinant proteins have the same biological activity as proteins produced using standard laboratory techniques, while researchers do not have to worry at all about traces of animal components or mammalian pathogens affecting their experiments.

MedChemExpress (MCE) provides key proteins in signaling pathways, transporters, or popular drug target proteins such as Wnt3a, Fibronectin, CLDN6, APOE2, etc.
