Check if the same lab product or an alternative is used in the 5 most similar protocols
Carbamazepine (CBZ) was obtained from Sigma-Aldrich (St. Louis, MO) and CBZ treatment was adapted from a previously published protocol [31 (link)]. CBZ was solubilized in 45% (2-hydroxypropyl)-ß-cyclodextrin (Sigma-Aldrich) to produce a 40 mg/ml stock solution. Following a baseline day, flies were transferred to 5% sucrose, 1% agar medium containing vehicle or CBZ at ZT 8, and nighttime sleep/wake parameters were calculated.

Carbamazepine and Morphine Pharmacokinetics

Check if the same lab product or an alternative is used in the 5 most similar protocols
Carbamazepine (CBZ) was purchased from Sigma (St. Louis, MO). Morphine sulfate salt and morphine-3-glucuronoide (M3G) was provided by NIDA Drug Supply Program (Rockville, MD). For in vitro studies, a 75 mM solution of CBZ was made up in dimethyl sulphoxide (DMSO). A 2.67-µl aliquot was taken directly from this stock and put into the 2 ml of bathing solution for the population data to obtain a final concentration of 100 µM [DMSO, 0.1% (v/v)]. For in vivo studies, CBZ was suspended in 5% DMSO (% of final volume) in saline (0.9%). Morphine was freshly prepared on the day of the experiment in saline such that the final dose was dissolved in 1 mL and administered by intraperitoneal (i.p.) injections.

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.
