Background Information

GAP SH3 Binding Protein 1 (G3BP1), also named as G3BP, is an effector of stress granule (SG) assembly. SG biology plays an important role in the pathophysiology of TDP-43 in ALS and FTLD-U. G3BP1 can be used as a marker of SG. It has been shown to function downstream of Ras and play a role in RNA metabolism, signal transduction, and proliferation. G3BP1 is a ubiquitously expressed protein that localizes to the cytoplasm in proliferating cells and to the nucleus in non-proliferating cells. G3BP1 has recently been implicated in cancer biology.

Patryk (Verified Customer) (03-18-2021)

I used the antibody for immunofluorescence imaging to label stress granules induced by treating the cells with with 50µM sodium arsenite. Used the antibody at a dilution 1:100 overnight at 4°C. Worked perfectly well, strong and specific signal. I am very satisfied of this antibody and strongly recommend if for immunofluorescence.
