S-Acylation is increasingly being recognized as an important dynamic posttranslational modification of cysteine residues in proteins. Various approaches have been described for assaying protein S-acylation with acyl-switch approaches being the most common and accessible. However, these approaches can be time-consuming with low reproducibility as a result of multiple protein precipitation/resuspension cleanup steps. Here we present a faster, cleaner, and more sensitive acyl-switch approach for detecting the S-acylation state of any protein, from any cell or tissue type, that can be detected by western blotting. In the case of acyl-RAC, the procedure is now performed without protein precipitation, greatly increasing speed and improving sample handling in the assay. This also allows for more samples to be processed simultaneously and opens the way for medium-throughput assays. Overall, maleimide scavenging improves the reliability of determination and quantification of protein S-acylation state by acyl-switch methods.
