7-33 (6mg) – Targeted Research Solution
B7-33 6mg is a high-affinity, soluble peptide derivative of the human gene H2 relaxin. Specifically engineered for research applications, this 6mg lyophilized vial offers a stabilized format for investigating the potent signaling pathways associated with tissue remodeling and cardiovascular physiology.
Unlike the full-length relaxin hormone, B7-33 is designed to be functionally selective. It focuses on the RXFP1 receptor, which researchers utilize to study the mitigation of fibrotic tissue accumulation and the promotion of vasodilation without the off-target effects often associated with broader hormone analogs.

B7-33 6mg is a synthetic research peptide derived from the relaxin hormone family, designed for laboratory studies focused on relaxin receptor signaling, tissue remodeling, and cellular communication pathways. B7-33 is particularly studied for its interaction with the RXFP1 receptor (Relaxin Family Peptide Receptor 1), which plays a role in regulating connective tissue, cardiovascular biology, and cellular repair mechanisms.
Unlike the full relaxin hormone, B7-33 is a single-chain peptide analog engineered to selectively activate certain relaxin-related pathways in experimental models. Because of this targeted activity, it has gained attention in research exploring fibrosis, tissue regeneration, and cell signaling.
The 6mg lyophilized peptide format allows researchers to work with a precise quantity suitable for controlled laboratory experiments and receptor interaction studies.
