..well you should...!

 The powerful T-Rex protein label combines excellent performance and photostability over a wide pH-range of 2-11.

It is therefore ideally suited for high performance visualization of protein samples separated in 2D gels. In contrast to green fluorescence protein stains or labels the red fluorescence of T-Rex causes almost no background.

Therefore the signal-to-noise ration of T-Rex is much better compared to most other fluorescence products on the market. 

T-Rex labeled proteins do not interfere with antibody recognition and mass spectrometry !
