All reagents were applied without purification. Histamine (His) (≥99%) was purchased from Sigma Aldrich Sdn. Bhd. Cadaverine (Cad), putrescine (Put), tyramine (Tyr), heptylamine (Hep), and spermidine (Spe) were bought at 99% purity and purchased from Sigma Aldrich Sdn. Bhd. Potassium hexacyanoferrate III (K₃ [Fe(CN₆]) and potassium hexacyanoferrate II-3-hydrate (K₄ [Fe(CN₆] 3H₂O) were obtained from Merch Sdn. Bhd. Sulfuric acid (H₂SO₄), ≥97%, and lithium perchlorate were purchased from Sigma Aldrich, and polyurethane (PU) was produced by Munir et al. [36 (link)]. The phosphate buffer solution (PBS) was obtained by the combination of sodium dihydrogen phosphate (Na₂H₂PO₄) and disodium hydrogen phosphate (Na₂HPO₄), and both reagents were purchased from Merck, Sdn. Bhd. Ultrapure Milli-Q water was applied throughout.

All reagents were applied
in this study without purification. The current study also employed
histamine (≥99%) purchased from Sigma Aldrich Sdn. Bhd. Potassium
hexacyanoferrate III (K₃[Fe(CN₆]) and potassium
hexacyanoferrate II-3-hydrate (K₄[Fe(CN₆] 3H₂O) were obtained from Merch Sdn. Bhd., sulfuric acid (H₂SO₄) (≥97%) and lithium perchlorate were
purchased from Sigma Aldrich, and PU was produced according to the
procedure outlined by Munir et al.²⁷ The
present study acquired phosphate buffer solution (PBS) by mixing sodium
dihydrogen phosphate (Na₂H₂PO₄) and
disodium hydrogen phosphate (Na₂HPO₄), which
were both purchased from Merck, Sdn. Bhd. This study also utilized
ultrapure Milli-Q water.

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.
