Descrição

Descrição geral

Maleimide is an unsaturated imide[1] used in protein conjugation reactions.[2] The direct measurement of maleimide moieties following conjugation reactions by spectrophotometric analysis at 302 nm is insensitive due to the small extinction coefficient (620M-1 cm-1) and complicated by protein absorbance at this wavelength.

Adequação

Suitable for quantifying maleimide groups

Princípio

The colorimetric maleimide quantiation kit provides a simple and direct procedure for measuring maleimide groups. The sample is first reacted with a known amount of excess thiol and then the remaining unreacted thiol is assayed using 4,4′-DTDP (4,4′-Dithiodipyridine). The amount of maleimide is calculated as the difference between the initial amount of thiol and the amount of unreacted thiol after the complete reaction of all maleimide groups.
