(A) Schematic representation of the exon arrangement of human iGb3 synthase. Numbers (1–7) in the left-hand column denote the different primer combinations used in PCR analysis. Arrows define both primer direction and specific binding exons.
(B) PCR products generated from dendritic cell cDNA template using the primer combinations described above. Numbers on the left are size markers (kilobases).
(C) Schematic representation of the exon arrangement of human iGb3S. Numbers (1–4) in the left-hand column denote the different primer combinations used in PCR analysis. Arrows define both primer direction and specific binding exons.
(D) PCR products generated from dendritic cell cDNA template using the primer combinations described above. Numbers on the left are size markers (kilobases). Using these and other primer combinations, these PCR experiments were repeated several times.
