Kassinin vs Ranatensin

Kassinin vs Ranatensin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Kassinin
Neuropeptide / Tachykinin

Kassinin is a tachykinin peptide isolated from the skin of the African frog Kassina senegalensis. It preferentially activates NK2 receptors, distinguishing it from physalaemin (NK1) and making it valuable in delineating NK2 receptor pharmacology....

Ranatensin
Neuropeptide / Tachykinin

Ranatensin is an 11-residue tachykinin peptide isolated from the skin of the North American frog Rana pipiens. It belongs to the same tachykinin family as substance P and physalaemin, sharing the conserved C-terminal Phe-X-Gly-Leu-Met-NH2 sequence....
