Direct nucleotide sequencing of posttransplant H CDR3s. Shown are the 6 representative panV_H CDR3 sequences from patients no. 1, 9, and 11. J_H family assignments are shown in parentheses following the sequences. Also shown are the germline (GL) D_H sequences that match CDR3s. Asterisks represent gaps introduced to optimize homology. N- and P-nucleotides are underlined. Italic letters represent P-nucleotides. CDR3 aa sizes are shown.
