Rhodopsin Epitope Tag is a 9-amino acid peptide localized within the C-terminal region of bovine rhodopsin . Rhodopsin Epitope Tag is widely used as an epitope tag and can be recognized by a number of anti-rhodopsin antibodies. The specificities of four monoclonal antibodies rho 1D4, 1C5, 3A6, and 3D6 prepared by immunization of rod outer segments containing rhodopsin have been defined using synthetic peptides. All of these antibodies interact within the 18 residues at the COOH terminus of rhodopsin and recognize linear antigenic determinants of 4-11 residues[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

3x DYKDDDDK Tag is a useful tool for investigating the function and localization of proteins whose antibodies (Abs) are not available. Often it is also used in a 3X FLAG format (3x DYKDDDDK Tag) for purifying difficult proteins that accumulate in low abundance [1][2].

体外研究
(In Vitro)

HEK293 cells transiently transfected with HARS-expressing plasmids were harvested and lysed in CelLytic M buffer containing mammalian protease inhibitor cocktail for 20 min at 4 °C. FLAG-tagged HARS is purified by binding to an anti-DYDDDDK resin per manufacturer protocol and eluted by competition with 3X-DYKDDDDK peptide in buffer containing 50 mM Tris-HCl pH 7.4, and 150 mM NaCl (purification of human HARS)[2].
