生化/生理作用
在与低分子量硫醇发生共轭反应之前，单溴二胺基本上是不发荧光的。与普通的单溴二胺不同，它带有正电荷，因此可以通过电泳或阳离子交换色谱法分离缀合物
包装

Techniques have been developed to measure the reactivity of free thiols in the HLA class I antigen-binding cleft. HLA-B27, which sequencing predicts has a free cysteine at position 67, reacts rapidly with the positively charged thiol reagent monobromotrimethyl-ammoniobimane bromide (qBBr)

Monobromobimane (mBBr, bimane), a compound that penetrates cells and forms a fluorescent adduct with thiol groups, was used to asses the significance of thiols in platelet function. Exposure of washed platelets for 1 min to 100 microM mBBr abolished ADP-induced

Fluorescent localization of thiols and disulfides in marsupial spermatozoa by bromobimane labelling.
K E Mate et al.
Molecular reproduction and development, 37(3), 318-325 (1994-03-01)
The acrosome of marsupial spermatozoa is a robust structure which, unlike its placental counterpart, resists disruption by detergent or freeze/thawing and does not undergo a calcium ionophore induced acrosome reaction. In this study specific fluorescent thiol labels, bromobimanes, were used
