B7-33 is a synthetic single-chain peptide corresponding to the B-chain of human relaxin-2, held as a research material for laboratory use.
Scientific publications have placed the peptide across extracellular matrix and connective tissue biology, fibrotic signalling, relaxin biology, receptor pharmacology, cardiovascular biology, and molecular signalling.
The same body of work records the peptide within laboratory studies covering receptor interactions and the cellular signalling pathways connected to them, where it remains a subject of continuing scientific research. Supply is as lyophilized powder in vial format.
