Proteins and Peptides

Proteins are used in routine laboratory procedures such as binding enzymes or coupling peptides to carrier proteins. These kits, mixture solutions, and collagen matrices fulfill a myriad of essential laboratory functions for developing relationships between proteins and other cellular components. The stimulating proteins offered have various amino acid arrangements and functions to fulfill any sample manipulation for testing purposes in any field.

Human/Mouse Recombinant IHH (from E. coli)

Human/Mouse Recombinant IHH (from E. coli)

Supplier: VWR International
