Regarding chemicals, 0.01 M phosphate buffered saline (PBS) powder sachets (0.01 M NaH2PO4, 0.138 M NaCl, 0.0027 M KCl), Tris(hydroxymethyl)-aminomethane (Trizma base, ≥99.9%), sodium chloride (NaCl ≥ 99.5%), sodium hydroxide pellets (NaOH, ≥97%), mercuric chloride (HgCl2, ≥99.5%), L-cysteine (Cys, ≥98% purity), and L-glutathione reduced (GSH, ≥98% purity) were purchased from Sigma-Aldrich (St. Louis, MO, USA). HCl (plasma pure 34–37%) was purchased from SCP Science (Baie D’Urfe, QC, Canada), while CH3HgOH (aqueous 1.0 M solution) was obtained from Alfa Aesar (Haverhill, MA, USA). Arsenobetaine bromide (AB) was synthesized according to a previously published procedure, and its recrystallization from ethanol yielded white crystals with a melting point of 225 °C (literature: 227 °C) [53 (link)].

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.
