生物活性

L-Carnosine is a dipeptide composed of beta-alanine and histidine. L-Carnosine is an endogenous metabolite found in human brain, muscle and gastrointestinal tissues and is present in all vertebrates. L-Carnosine is a non-enzymatic free radical scavenger and natural antioxidant with anti-inflammatory and neuroprotective properties that can inhibit biochemical changes associated with aging[1][2][3].

體外研究
(In Vitro)

L-Carnosine is a dipeptide of the amino acids beta-alanine and histidine and has the potential to suppress many of the biochemical changes that accompany aging[1].
L-Carnosine also exhibits some antioxidant effects. The antioxidant mechanism of L-Carnosine is attributed to its chelating effect against metal ions, superoxide dismutase (SOD)-like activity, and ROS and free radicals scavenging ability[2].

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

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
