All materials used were
HPLC grade unless
otherwise indicated. Sodium hydroxide, sulfuric acid, sodium cyanide,
KH₂PO₄, K₂HPO₄, and NH₄OH were purchased from Fisher Scientific (Hanover Park, IL).
2,3-Naphthalene dialdehyde (NDA) was obtained from TCI America (Portland,
OR). Taurine (2-aminoethane sulfonic acid) and NaBO₂·4H₂O were purchased from Alfa Aesar (Ward Hill, MA). NaSCN was
purchased from Acros Organics (Morris Plains, NJ). Human serum albumin
(HSA) and NaHS were purchased from Sigma-Aldrich (St. Louis, MO).
Phosphate (0.1 M)/borate (0.05 M) buffer and stock solutions of sodium
hydroxide (1 M), sulfuric acid (1 M), and NaSCN (1 mM) were prepared
in deionized water. sodium cyanide standards and NaHS were obtained
by dilution from 1.8 mM and 1 M stock solutions, respectively, with
10 mM NaOH. NH₄OH was prepared by diluting the original
aqueous solution (29% by weight or 14.5 M) to 30 μM in deionized
water. The NDA (2 mM) stock solution was prepared in phosphate/borate
buffer and 40% methanol. A taurine (50 mM) solution was prepared in
phosphate/borate buffer. A standard HSA solution was obtained by dissolving
3.3 mg of HSA per mL of deionized 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.
