[Nle11]-Substance P is a substance P analog that avoids methionine oxidation problems.

体外研究
(In Vitro)

Substance P and its analog, [Nle11]-Substance P have shown similar potency in tests. The spasmogenic activity of Substance P and [Nle11]-Substance P are preserved in the same potency order on stimulated guinea-pig ileum[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
