I've used it for Westerns and immunofluorescence. Works fine in Westerns,
but the batch I got was a bit dirty--I had to clean it up by pre-adsorbing
with acetone powder. Once I did that, it give crisp and clear detection
of a single band (presumably GFP !). I could get away with a 1:10,000
dilution for a Western dectecting GFP expressed in E.coli.
In immunofluorescence in mammalian cells, the background seems quite low. See
for a couple of immunofluorescent images with the anti-GFP antibody.
