FLAG tag the octapeptide sequence and artificial epitope binds to the FLAG antibody. I want to know in which region of the FLAG antibody does the FLAG epitope binds ?
Antibodies bind their epitopes in the complementarity determining region, which is within the Fab part of the molecule.
Hi Puneeta, I have heard from many researchers that the FLAG-tag purification is very expensive and not worth the cost.
Hi, My research project had numerous results and because the conference paper is usually just 5-6 pages long, I could not discuss all my results in it. However, is it still possible to mention...
