B7-33 vs Full-Length Relaxin in Research Models

By: Mindful Research Team1 min read

Key takeaways

  • B7-33 is a single-chain peptide; full-length relaxin is a two-chain hormone.
  • Both target RXFP1.
  • The single-chain design is simpler to synthesize and characterize.
  • It is a simplified tool for studying RXFP1 signaling in vitro.
  • For in vitro research use only.

B7-33 differs from full-length relaxin in being a single-chain peptide rather than a two-chain hormone, which makes it a simpler tool for studying RXFP1 activation in vitro. This guide compares the two.

Structural difference

Full-length relaxin is a two-chain, disulfide-linked peptide; B7-33 is a single chain derived from relaxin’s B-chain.

Why it matters in research

A single-chain peptide is simpler to synthesize and characterize, which is useful when studying RXFP1 signaling without the complexity of the two-chain structure.
