Genomic profiles of G12 and other P[6] rotavirus strains having long (L) and short (S) electropherotypes. Lanes 1 to 3 (long) and 4 and 5 (short) represent G12P[6] strains; lanes 6 (short) and 7 (long) were G9P[6] strains; lanes 8 and 9 represent G2P[6] strains with a long RNA migration pattern. Reference strains, L26 (G12P[4]), RV024 (G12P[6]), Se585 (G12P[6]), 116E (G9P[11]), and DS1 (G2P[4]), were also included for PAGE.
