A user interface for a radio frequency identification interrogation system is disclosed, which interface may include graphics, sounds, lights, or combinations of the foregoing that provide information to a user in regard to the materials being interrogated. These hydridomas are obtained by fusing mouse spleen cells having a high antibody titer against neurosin with mouse-derived myeloma cells, screening fused cells being highly reactive with neurosin, and thus producing an antibody binding specifically to neurosin. The method includes selecting a business object of an application executing in memory of a computer for cloning and ascertaining a contemporaneous state of the selected business object. This apparatus allows execution of low-cost and high-resolving-power ion separation and detection.
