High affinity cross-reacting mAb generated by minimal mimicry: implications for the pathogenesis of anti-nuclear autoantibodies and immunosuppression.

abstract：:Herpes simplex virus type 2 (HSV-2) DNA was treated with four restriction endonucleases (EcoRI, HincIII, Bgl II, and Xba I) and eight fragments were purified and labeled with 32P in vitro. The kinetics of renaturation of each of the fragments was measured in the presence of DNA extracted from 333-8-9, a hamster cell l...
