Check if the same lab product or an alternative is used in the 5 most similar protocols
Capillary electrophoresis time-of-flight mass spectrometry (CE-TOFMS)-based metabolome analysis of fecal samples was conducted as described previously (Hirayama et al., 2012 (link)) with some modifications. In brief, fecal samples were lyophilized using a VD-800R lyophilizer (TAITEC) for 24 h. Freeze-dried feces were disrupted with 3.0-mm Zirconia Beads (Biomedical Science) by vigorous shaking (1,500 rpm for 10 min) using the Shake Master (Biomedical Science). Fecal metabolites were extracted using the methanol:chloroform:water extraction protocol (Wang et al., 2015 (link)). CE-TOFMS experiments were performed using the Agilent CE System, the Agilent G3250AA LC/MSD TOF System, the Agilent 1100 Series Binary HPLC Pump, the G1603A Agilent CE-MS adapter, and the G1607A Agilent CE-ESI-MS Sprayer kit. In-house software (MasterHands) (Sugimoto et al., 2010 (link)) was used for data processing, quantification, and peak annotation.

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.
