Thiol assay
Webover this range. Therefore, to directly assay for thiol and disulfide levels present in the entire sample and to avoid tedious frac-tionation procedures, the direct colorimetric assay was developed. Chemical and physical aspects of the direct colorimetric assay. A schematic of the mixed-phase method is shown in Figure 2. WebThe assay, performed at room temperature, can be completed in 5 min. As low as 2 - 10 uM free thiols can be detected, including low-molecular weight thiols and those thiol groups on proteins. Each kit provides sufficient material for 250 assays, and includes a cell/tissue extraction solution for preparation of crude lysates for the assay. The ...
