Ibuprofen

Manufactured by Fujifilm
Sourced in Japan

Ibuprofen is a pharmaceutical product used for the analysis and quantification of ibuprofen, a common non-steroidal anti-inflammatory drug (NSAID). It is a laboratory equipment designed to accurately measure the concentration of ibuprofen in various samples, such as pharmaceutical formulations, biological fluids, or environmental samples. The core function of this product is to provide researchers and analysts with a reliable and precise tool for the detection and quantification of ibuprofen, which is essential for quality control, pharmacokinetic studies, and environmental monitoring.

Probing PEPT1-Mediated Glycylsarcosine Uptake

Check if the same lab product or an alternative is used in the 5 most similar protocols
The culture medium was removed and the cells were preincubated with the transport buffer (Hanks’ balanced salt solution containing 10 mM 2-(N-morpholino)ethanesulfonic acid (MES), pH 6.0) at 37 °C for 15 min. The uptake assays were initiated by replacing the medium with transport buffer containing 135 nM [3H]glycylsarcosine at 37 °C in the presence or absence of 3 mM ibuprofen (Wako Pure Chemical Industries) (PEPT1 inhibitor) or at 4 °C. Uptake was stopped by the addition of ice-cold transport buffer; the cells were rinsed using the same buffer. The cells were lysed with 0.2 M NaOH solution (0.5 mL/well) containing 0.5% sodium dodecyl sulfate (SDS). Radioactivity was measured through liquid scintillation counting, using 3 mL Clear-sol I (Nacalai Tesque, Inc., Kyoto, Japan) as the scintillation fluid. The total protein in differentiated cells was measured using the Pierce™ BCA Protein Assay Kit (Thermo Fisher Scientific).

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.
