Aniseed Oil and Thymol Solubilization in Phosphate Buffer

Check if the same lab product or an alternative is used in the 5 most similar protocols
D-Glucose, L-Lysine monohydrochloride and linalool were purchased from Acros Organics, thymol from Applichem and anise oil from Sigma Aldrich (CAS: 8007-70-3, nature identical, synonym: aniseed oil). All solutions (glucose, lysine and the test compounds) were prepared in phosphate buffer 0.1 M, pH 7.2 ± 0.1 (PBS, Bectron, Dickinson and Company, Bergen County, NJ, USA) and Tween 80 (Serva Electrophoresis GmbH, Heidelberg, Germany) which helps to incorporate aniseed oil and thymol in phosphate buffer. As linalool possesses a very good aqueous solubility at pH 7.0, the use of Tween 80 was not necessary [26] (link).

Working solutions were then diluted in 10% DMSO, 10% Tween-80, and 80% USP saline for injections. Rimonabant (Tocris, #0923) was made up in DMSO and then diluted to 20% DMSO, 10% Tween-80, and 70% USP saline for injections. Istradefyllene (Tocris, #5147) was made up in DMSO and then diluted to 20% DMSO, 10% Tween-80 and 70% saline for injections. Morphine sulfate pentahydrate (from the NIDA Drug Supply Program) was dissolved in USP saline. Vehicle injections were matched accordingly as a control in each experiment. All solutions were made immediately before use without long-term storage. For in vitro experiments, 100 mM stocks of terpenes, and 10 mM stocks of all other compounds, were made up in DMSO. DMSO concentrations in assays were maintained at 1% or lower. Vehicle controls were matched accordingly.

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.
