Forlabeling100µgantibody(assumingthetargetantibodyconcentrationis1mg/mL),mix5µL(5%ofthetotalreactionvolume)ofReactionBuffer(ComponentC)with100µLofthetargetantibodysolution.
Note1:Ifyouhaveadifferenceantibodyconcentration,adjusttheantibodyvolumeaccordinglytomake~100µgantibodyavailableforyourlabelingreaction.
