说明

Biochem/physiol Actions

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

Localization of thiol and disulfide groups in guinea pig spermatozoa during maturation and capacitation using bimane fluorescent labels.

T T Huang et al.

Biology of reproduction, 31(4), 797-809 (1984-11-01)

The distribution of thiols and disulfides in the guinea pig spermatozoon during maturation and capacitation was studied using both membrane-permeable (mBBr) and impermeable (qBBr) forms of bromobimane, a specific fluorescent probe for thiol groups. In conjunction with the disulfide (SS)-reducing

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
