A method for capillary electrophoretic analysis of a biological sample, comprising using negatively surcharged modified antibodies so that they migrate to a zone located outside the migration zone for proteins from the biological sample when they are separated during electrophoresis is disclosed. The electrical pulses can be provided either unilaterally or bilaterally and can be supra-diaphramatic or be sub-diaphramatic. Accordingly, a ultra-high performance base station and terminal having no-interference reception performance as well as achieving high hardware and power efficiency may be realized. At least two of the shaped elements are fixed in a shaped element composite in a positional relationship with respect to one another with a first plane of a first shaped element overlaps in sections a second plane of a second shaped element.
