FLAG epitope - sources and advice

[David Clayton]

I need to put a small epitope onto a protein to allow detection of it in 
cultured cells and perhaps tissues.  I have the impression that the FLAG 
epitope might be a good choice for this. Questions:
1) is there a commercial source for FLAG-epitope related reagents?
2) Anybody want to offer opinions as to the utility of FLAG, vs. other 
candidates such as His, myc, HA, etc?
Any advice appreciated!
