The Claim

Collagen extracted from cannonball jellyfish (Stomolophus sp.2) shows α-chain bands (α1 and α2) and higher-molecular-weight β and γ components on SDS-PAGE that are consistent with type I collagen.

Verified by Lenz ·

The Short Version

Primary studies on blue cannonball jellyfish report SDS-PAGE profiles with α1/α2 chains and β/γ components that match the classic pattern associated with type I collagen. Because the claim says the pattern is “consistent with” type I rather than proving identity, the evidence supports it well. The main limitation is that SDS-PAGE alone is supportive, not conclusive, for collagen typing.

Caveats

  • SDS-PAGE banding supports a type I-like pattern but does not by itself definitively establish collagen type.
  • Some studies on jellyfish collagen report additional proteins or alternative collagen classifications, so the result should not be read as exclusive proof of pure type I collagen.
  • Taxonomic labels vary across the Stomolophus literature, so the strongest support comes from sources explicitly examining Stomolophus sp. 2 or clearly linked blue cannonball specimens.
