  1. aDominant bands containing ≧50% and 45–50% of the counts within a CD8+ TCR-specific PCR product were sequenced directly with CB-R and/or specific BJ-R primers to establish oligoclonality. The sequence success rate was determined on the basis of cleanly readable dominant sequence with no discrepancies at all.
  2. bThe percentage of those dominant bands containing ≧50% and 45–50% of the counts in which direct sequencing with CB-R and/or BJ-R primers yielded sequences with discrepancies at 1, 2, 3, or >3 nucleotide (nt.) positions.
