Description GFP-Trap® coupled to fluorescent dye ATTO 488

Relevance

GFP is a powerful tool to study protein localization and dynamics in living cells. However, the photo stability and the quantum efficiency of GFP is not sufficient for Super-Resolution Microscopy (e.g. 3D-SIM or STED) of fixed samples from cells expressing GFP-fusion proteins to visualize specific structures. Furthermore, many cell biological methods such as HCl treatment for BrdU-detection, the EdU-Click-iT™ treatment or heat denaturation for FISH lead to disruption of GFP signal.
Here we offer our GFP-Booster _Atto488, a specific GFP-binding protein coupled to the fluorescent dye ATTO 488 (from ATTO-TEC) for reactivation, boosting and stabilization of GFP.

Specificity

GFP-Trap® efficiently detects and labels green fluorescent protein from Aequorea victoria and derivates thereof such as eGFP or eYFP but not eCFP.
Tested Applications and Recommended Dilutions
Immunofluorescence
 
Enhancement of GFP signal with GFP-Booster after EdU-Click-iT™ treatment. EdU-Click-iT™ treament leads to disruption of GFP signal. GFP-Booster labels GFP fusion proteins and thus reactivates and boosts the fluorescence.
