| Cat.No.: | Kit-0533 |
| Product Overview: | Maleimide Assay Kit is a quantitative assay for the determination of maleimide groups. |
| Description: | Maleimides can be directly assayed spectrophotometrically at 302 nm. However, the small extinction coefficient of 620 M-1cm-1 renders this assay insensitive, and the assay is further complicated by the protein absorbance at the same wavelength. |
| Applications: | This colorimetric maleimide assay kit quantifies maleimide groups by first reacting a sample with a known amount of thiol present in excess and then assaying the remaining unreacted thiol using 4,4"-DTDP with a molar extinction coefficient of 19,800 M-1cm-1. |
