B7-33 is a synthetic single-chain relaxin mimetic derived from the B-chain of relaxin, designed to selectively activate the RXFP1 receptor while reducing affinity for other relaxin receptors. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials. B7-33 is investigated in research on fibrosis, tissue remodeling and relaxin-receptor signaling, and is commonly applied in cell-culture and preclinical studies. The stable freeze-dried format supports easy reconstitution and reproducible dosing. B7-33 lets investigators study relaxin-family receptor signaling in engineered cell systems without the complexity of full-length relaxin, and dose-response experiments measure concentration-dependent receptor activation and downstream responses. Its reduced sequence simplifies handling and analysis. The lyophilized material reconstitutes reliably for dose-response work, and our records verify purity. Trial and bulk quantities are available, with storage and shipping guidance. B7-33 ships with its analysis record and reconstitution guidance, and the lyophilized powder stays stable until use. Since receptor assays are usually dose-response based, we can provide multiple vial sizes from one lot to support the full concentration range, with packing matched to transit conditions. We are a professional peptide supplier with in-house quality control, offering both small trial packs and bulk quantities at factory-direct prices. Every order is packed carefully and dispatched with tracking, and our team provides responsive after-sales support for research customers worldwide.
