SampleProtocolforLabelingProteinswithtrFluor™TbMaleimide:
1. Dissolveyourthiol-containingproteinatconcentration1-10mg/mL(3-10mgistheoptimallabelingconcentration)usingPBSbuffer(20mM,pH7.2).
2. DissolvethetrFluor™TbMaleimideinDMSOattheconcentrationof10-15mg/mL(Forexample,tothe100µgtrFluor™TbMaleimideadd10µLDMSOtomake7mMdyelabelingsolution).
3. MixthetrFluor™TbMaleimide(fromStep2)andproteinsolution(fromStep1)at20:1molarratioofdye/protein,andshakethereactionmixtureatroomtemperaturefor2-4hoursinthedark.
