All chemicals were ACS grade or higher, purchased from Sigma Aldrich (St Louis, MO): styrene (substrate), styrene oxide (product), styrene glycol (product), benzyl alcohol (internal standard), acetaminophen (substrate), and 2-acetoamidophenol (internal standard). Barium hydroxide, zinc sulfate, 1,4-dioxane, HPLC grade methanol and HPLC grade acetonitrile were purchased from Fisher Scientific, Wilmington, MA. The acetaminophen-glutathione (APAP-GSH) and acetaminophen-cysteine (APAP-cys) adducts were synthesized in-house. For purification of adducts, solid-phase extraction Oasis MAX columns were obtained from Waters Corp. (Milford, MA). NAPQI solid was provided as a generous gift from Drs. Dean Roberts and Laura James at Arkansas Children’s Hospital (Little Rock, AR).

Measuring Intestinal Lactase and Sucrase

Check if the same lab product or an alternative is used in the 5 most similar protocols

Intestinal lactase and sucrase activities were measured as previously described (33 (link), 34 (link)). Briefly, mucosal homogenates were prepared and incubated with 0.6 M lactose (Thermo Fisher Scientific) or 0.3 M sucrose (Thermo Fisher Scientific) buffer (dissolved in 0.0625 M maleate buffer) for 60 min at 37°C. The reaction was stopped by the addition of 2.0% zinc sulfate (Thermo Fisher Scientific) and 1.8% barium hydroxide (Thermo Fisher Scientific), and the amount of glucose released was detected via a glucose oxidase reagent (Thermo Scientific). Enzyme activity was in μmoles glucose per minute per gram of protein. Protein was measured in intestinal homogenates via the Bradford method (Bio-Rad).

Intestinal lactase and sucrase activities were measured as previously described [28 (link),29 (link)]. Mucosal homogenates were prepared and incubated with 0.6 M lactose (Thermo Fischer Scientific, Hanover Park, IL, USA) or 0.3 M sucrose (Thermo Fisher Scientific, Hanover Park, IL, USA) buffer (dissolved in 0.0625 maleate buffer) for 60 min at 37 °C. The reactions were stopped by adding 2.0% zinc sulfate (Thermo Fisher Scientific, Hanover Park, IL, USA) and 1.8% barium hydroxide (Thermo Fisher Scientific, Hanover Park, IL, USA), and the amount of glucose release was detected by using a glucose oxidase reagent (Thermo Fisher Scientific, Hanover Park, IL, USA). Enzyme activity is expressed as µmoles glucose/minute/g protein. Protein was measured in intestinal homogenates using the Bradford method (Bio-Rad, Hercules, CA, USA).

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.
