If you're going to wholesale bulk durable b7 33 peptide, welcome to get quotation and free sample from our factory.
Product Description
B7 33 peptide is a synthetic single-chain research peptide derived from the B-chain fragment of human relaxin-2, consisting of 27 amino acids.
Unlike natural relaxin, this synthetic B7-33 retains only the key active fragment and dispenses with the complex double-chain structure; yet, it can still target the RXFP1 receptor and is specifically used in various experimental studies regarding organ fibrosis.

Research Applications
1. Research on cardiac fibrosis and myocardial injury
Used in animal models of myocardial infarction and myocardial injury to observe myocardial collagen accumulation and myofibroblast differentiation, as well as to investigate the mechanisms underlying cardiac remodeling and cardioprotection. Observed effects include reduced tissue collagen deposition and improved post-injury cardiac functional parameters; all results are derived from animal experiments.
2. Multi-organ fibrosis studies
The B7-33 peptide is utilized to investigate the mechanisms of sclerosis and scar formation in liver, kidney, and lung tissues, and to screen for potential anti-fibrotic targets.
3. Research on RXFP1 receptor biased agonist mechanisms
Used to distinguish the specific biological effects mediated by the ERK1/2 and cAMP downstream pathways; by comparing it with native relaxin, researchers can determine which pathway drives the anti-fibrotic effect, making it a popular tool peptide for pharmacological pathway analysis.
4. Experiments on vascular and endothelial protection
Used in vascular injury models to study endothelial protection and vascular remodeling; due to its weak activation of the cAMP pathway, it allows researchers to isolate the effects from cAMP-mediated vasodilation and specifically examine tissue changes driven by the ERK pathway.
