The present invention provides a presentation system and method of use for quantifying a target moiety in a sample which may contain the target moiety, the method comprising using a specified concentration or varying the concentration of a presentation system in order to generate a comparison poi nt or calibration curve which provides means for comparing a signal generated b y the presentation system and a signal generated by a sample, wherein said presentation system comprises at least one copy of said target moiety or par t thereof covalently attached to a domain of a scaffold wherein the domain is non-reactive to a binding partner specific to said target moiety.
