Chemicals used in the experiments were purchased from Cayman Chemical (Ann Arbor, MI, USA), including 6-shogaol, TRPA1 antagonist HC-030031. Capsaicin (CAP), Allyl isothiocyanate (AITC), and cinnamaldehyde were purchased from Sigma-Aldrich (St Louis, MO, USA). The stock solution of capsaicin (10 mM) was prepared in ethanol and working solutions were prepared freshly by the day of use. AITC and cinnamaldehyde were prepared freshly with KBS. All other chemicals (6-shogaol and HC-030031) were prepared freshly with KBS within one hour before application.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
