Summary of anti-EBNA1 murine mAbs.

WB: Western blot, WB': Western blot signal with endogenous EBNA1, ELISA: the average ELISA signal when adding equal concentrations of purified mAb to an EBNA1-coated well, PR-mAb: polyol-responsive mAb, IP: immunoprecipitation, Supershift: ability to bind to EBNA1/DNA complex and change its mobility during non-denaturing gel electrophoresis, NYT: not yet tested. Epitope was determined as in Fig. 1. *particularly high affinity for endogenous EBNA1. aresponsive to salt alone.
