RhodopsinEpitopeTag, a 9-amino acid peptide representing the C terminus of bovine rhodopsin, is widely used as an epitopetag recognized by various anti-rhodopsin antibodies.
The recognized V5 epitope represents 95GKPIPNPLLGLDST108 of RNA polymerase α subunit of simian parain uenza virus type 5. This short peptide sequence was chosen because high-af nity antibodies can be reliably produced in many different species1.
