Xen-dorphins — frequently asked

What are Xen-dorphins?
Xen-dorphins are a named series of amphibian skin peptides associated with Xenopus secretions and supplied here as synthetic analogues. Published information on the series is limited, so they are generally treated as exploratory research standards rather than well-characterised pharmacological tools.
Why are amidated and non-amidated versions listed?
Many amphibian skin peptides are naturally amidated at the C-terminus, a modification often reported to influence stability and receptor interaction. Supplying both forms lets researchers compare them directly and determine whether amidation matters in their particular assay system.
What are these peptides used for?
They are typically used as synthetic reference material for analytical characterisation, purity and stability testing, mass spectrometry standards, and exploratory screening. Because supporting literature is sparse, investigators are expected to validate identity and behaviour independently before interpreting any result.
