Characterization of K1-18 Ab.

<p>(A) Binding activity of K1-18 Ab to 1-69Abs. Binding activity of K1-18 Ab to 1-69Abs was examined by ELISA. F004-122, F009-165, F021-112, F021-256, F035-095, and F058-031 are not 1-69Abs. The group number is indicated under the name of the clone. (B) Binding activity of 1-69Abs to virus particles under the presence of K1-18 Ab. Binding activity of 1-69Abs to Bri07 virus particles was examined under the presence of 100 or 200 µg/ml K1-18 Ab by ELISA. F008-009 is not anti-HA Ab and was used as a negative control. The group number is indicated under the name of the clone. The experiment was performed in duplicate, and the error bars show standard deviation.
