Southern blot analysis of Ig gene configuration in the EU12 subpopulations.
gDNA from placenta and sorted EU12 subpopulations was digested withBglII before hybridization with a JH probe for IgH chain gene analysis (A), or with EcoRI before hybridization with a Cλ probe for Igλ L chain gene analysis (B). Arrows indicate HC and LC gene rearrangements in the R3 subpopulation.
