Deuterium oxide d2o

Manufactured by J&K Scientific
Sourced in China

Deuterium oxide (D2O), also known as heavy water, is a colorless, odorless, and tasteless liquid. It is an isotopic form of water in which the hydrogen atoms have been replaced by deuterium, a stable isotope of hydrogen. Deuterium oxide has a slightly higher density than regular water and a higher boiling point.

Fatty acid-free HSA was purchased from Sigma Aldrich (Milwaukee, USA) and used without further purification. BPB (purity > 99%), BPE (purity > 99%), deuterium oxide (D2O, 99.9% purity), dimethyl sulfoxide-d6 (DMSO-d6), and 5-dimethylaminonaphthalene-1-sulfonamide (DNSA) were purchased from J&K Scientific, Ltd. (Beijing, China). Dansylsarcosine (DNSS) was obtained from Heowns Biochemical Technology Co., Ltd. (Tianjin, China). All other reagents were of analytical grade and used without further purification.

HSA (approximately 99% and fatty acid-free) was purchased from Sigma Chemical Company (USA), and MLN8237 was purchased from Selleck (USA). Warfarin sodium, ibuprofen, deuterium oxide (D2O, 99.9% purity), and dimethyl sulfoxide-d6 (DMSO-d6) were purchased from J&K Scientific Ltd. (China). The HSA stock solution was prepared in 0.1 M PBS at pH 7.4. The MLN8237 stock solution was also prepared by dissolving an appropriate amount of the drugs in DMSO. All reagents were of analytical reagent grade, and thrice-distilled water was used throughout the experiment.

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.
