The molecule is an L-lysyl-L-glutamine dipetide in which the N(6) of the lysyl residue is linked to an acid-form fluorescein derivative and the glutamine residue carries an N-(2,4-dinitrophenyl)-L-alanine-containing substituent. It is used as a fluorescently labelled hapten. It has a role as an epitope and a hapten. It contains a 2,4-dinitrophenyl group.
