from ThermoFisher Scientific. Premixed 10× Tris/glycine/SDS electrophoresis
buffer (25 mM Tris, pH 8.3; 192 mM glycine; 0.1% SDS) was purchased
from BioRad. Deionized water (18.2 MΩ) was obtained using an
Ultrapure water system from Millipore. N-[3-[(3-Benzoylphenyl)formamido]propyl]
methacrylamide (BPMAC) was custom synthesized by PharmAgra Laboratories.
Note that the BPMAC used in the previous studies was synthesized in-house17 (link),18 (link) and is a positional isomer (para-form, N-[3-[(4-benzoylphenyl)formamido]propyl]
methacrylamide) of the BPMAC used in the present study.

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.
