The pool of Vγ2-Jγ1.2+ sequences in cord blood mononculear cells (CBMC) is dominated by public clonotypes. Vγ2 sequences from six fresh CBMC specimens were cross-compared and public clonotypes were identified. Public Vγ2 clonotypes are amino acid sequences present in two or more donors and identical at all positions in V, N and J regions. Abundance of public (a) Jγ1.2⁺ and (b) Jγ1.3/2.3⁺ clonotypes, as well as their proportion in the Vγ2 pool or Jγ1.2 or Jγ1.3/2.3 subset are shown for six CBMC specimens. Shaded clonotypes can be encoded by germ-line sequences; bolded clonotypes are present in every specimen.
