An epitope is an antigenic determinant, a biological structure or sequence to which an antibody binds. Proteins of interest are often expressed as fusion proteins which comprise an epitope tag. The most commonly used epitope tags include among others 6-His tag, HA tag, c-Myc tag, as well as proteins like Green Fluorescent Protein (GFP), Glutathione S-Transferase (GST)…

Covalab offers highly specific antibodies to a wide range of these tag epitopes. Our antibodies are tested by several methods to make sure of their specific and efficient performance.
