Biotin-maleimide- 0.01 mg/ml in PBS containing 0.1% Tween 20, incubated for 1 h at room temperature can be used to detect deprotected cysteine thiols present on immobilized peptides.

Biotin-maleimide is a biotin specific thiol containing reagent used to biotinylate different proteins through artificially induced or natural sulphadryl group. It can be used as a universal, multipurpose, thiol-specific probe. Biotin-maleimide can also be used in dot blots to detect protein SH groups.
