The B1267 Biotin-maleimide is a white powder that is soluble in DMSO at 10mg/ml, resulting in a clear colorless solution. A stock solution of the product in DMSO at 20 mg/ml can be prepared without the need for heat. This solution can then be diluted 1:10 with an aqueous buffer system, such as PBS or other. Concentrations of 40-50 mg/ml can also be prepared, but heat, i.e. 40°C, is needed. For most applications, a stock of 20 mg/ml would be suitable.

General description
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[1].
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[2].
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.
