Proteins and Peptides

Proteins are essential components of all living cells, as they fulfill countless biological functions within organisms. These functions comprise, for example, enzyme catalysis, defense against pathogens, transport of molecules, structural maintenance of the cell and regulatory functions. Major protein goups are antibodies, enzymes, cytokines, hormones, signalling peptides, structural components and transport proteins. We offer a broad portfolio of protein products, including recombinant proteins, enzymes, cytokines and peptides, for researchers in molecular biology, cell biology, biochemistry and many other scientific fields. The products can be used for a large variety of investigations and applications, such as protein-protein interaction and protein localisation studies, enzymatic assays, Western blots (e.g. as control) and immunohistochemistry.
