Whereas natural relaxin consists of two chains connected by disulfide bridges, B7-33 is a single-chain analog. This makes the compound significantly simpler and more stable to produce than the full hormone. Supplied as freeze-dried powder, 6 mg per sealed vial.<\/p>\n<p>B7-33 binds to the RXFP1 receptor, the same receptor as relaxin-2, but with a different signal profile: the compound primarily activates the ERK pathway and the cAMP pathway much more weakly. This separate action makes B7-33 interesting in research as a tool to study the two signaling pathways of the same receptor independently.<\/p>\n<h2>What is B7-33 being investigated for?<\/h2>\n<p>Within controlled research environments, B7-33 is addressed in, among other things:<\/p>\n<ul>\n<li><strong>Receptor binding:<\/strong> affinity and activation of the RXFP1 receptor.<\/li>\n<li><strong>Signal selectivity:<\/strong> the preference for the CEFR route over the cAMP route, and what that distinction yields in cell models.<\/li>\n<li><strong>Connective tissue models:<\/strong> collagen deposition and matrix turnover in cultured fibroblasts.<\/li>\n<li><strong>Comparative study:<\/strong> the single-chain analog alongside complete relaxin-2.<\/li>\n<li><strong>Peptide chemistry:<\/strong> stability and solubility of the single-chain structure relative to the two-chain hormone.<\/li>\n<li><strong>Analytical reference:<\/strong> Calibration substance for peptide analysis via LC-MS.<\/li>\n<\/ul>\n<p>It is important to emphasize that these applications take place exclusively within controlled research environments and that B7-33 is the subject of scientific research.<\/p>\n<h2>Buy B7-33 for research purposes<\/h2>\n<p>We supply B7-33 exclusively as a research chemical for professional laboratory research.
