Overview
What it is.
B7-33 is a single-chain peptide engineered to mimic a therapeutic domain of relaxin-2, a hormone studied for anti-fibrotic and tissue-remodeling effects, without relaxin's full structural complexity — designed for research into a more stable, single-chain research alternative.
Research Areas
- Studied for its relaxin-receptor-pathway activity in a simplified single-chain structure
- Studied for its potential role in anti-fibrotic, tissue-remodeling research
- Studied as a stability-focused alternative to native relaxin-2 in research settings

How it works.
B7-33 is a single-chain peptide engineered to mimic a specific therapeutic domain of relaxin-2, a hormone studied for anti-fibrotic and tissue-remodeling effects, without replicating relaxin's full, more complex two-chain structure.
It's studied for activating the relaxin receptor (RXFP1) through a simplified structure, an approach researchers are examining as a more stable, single-chain alternative to native relaxin-2 for anti-fibrotic and tissue-remodeling research.

The Evidence
Preclinical animal models
B7-33's anti-fibrotic and relaxin-receptor activity has been documented primarily in rodent studies; there is no published human clinical trial data specific to this engineered peptide.
Early-stage structural-biology research
Much of the published work centers on demonstrating that the simplified single-chain design retains relaxin-receptor activity, rather than establishing broad therapeutic outcome data.

B7-33 FAQ
Questions
B7-33 FAQ
What is B7-33 studied for?+
B7-33 is studied for its relaxin-receptor-pathway activity and its potential role in anti-fibrotic, tissue-remodeling research.
What does B7-33's 'single-chain' design offer over native relaxin-2?+
It's engineered to mimic a therapeutic domain of relaxin-2 without relaxin's full structural complexity, studied as a more stable, single-chain alternative for research settings.
How should B7-33 be handled and stored?+
It ships as a lyophilized powder in a single 10 mg size. Reconstitute with bacteriostatic water and refrigerate at 2–8°C after mixing — good for roughly 4–6 weeks refrigerated, or up to 24 months unreconstituted in a cool, dry place.
What testing does this batch undergo?+
Every batch is HPLC tested for purity and identity, plus sterility and endotoxin screening, before release. The Certificate of Analysis for that lot ships with your order.
