Immunoselection techniques for cloning DNA-encoding parasite-specific antigens.
New techniques sometimes generate a 'band- waggon' effect, with research workers keen to jump on and apply the technique in their own favourite field without always pausing to consider why. Michael Miles and Louise Clarke describe a new technique which they are applying to a well-defined and valuable end - improvement in the differential diagnosis of parasitic infections.
