Application: 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.
Application: Sulfhydryl-specific biotinylation reagent. Couples by highly efficient thioether linkage. Typically used to couple to intrinsic sulfhydryls, e.g. protein, and avoid modification of primary amine.
