Fig 1: TcdBUK1 lacks significant ability to interact with FZD2. The wells of an ELISA plate were coated with TcdBVPI or TcdBUK1 followed by treatment with CSPG4-EC-GFP (1 nM) (A), FZD2-Fc (4 nM) (B), or PVRL3 (100 nM) (C). The amount of plate-bound CSPG4, FZD2, or PVRL3 was detected using each of the respective antibodies. Results are representative of at least two independent experiments. Error bars represent the mean deviations of results from duplicate samples.
