Fig. 1From: Preparation of a highly specific and sensitive monoclonal antibody against tilmicosin and its application in lateral flow immunoassayESP energy, Mulliken atomic charges and molecular overlap of haptens and target. A ESP energy of haptens and target. Red, blue, and white indicate negative ESP regions, positive regions, and neutral regions, separately. B Mulliken atomic charges of targets and haptens. Only heavy atoms belonging to targets and haptens are shown. C Molecular overlay based on the lowest energy conformation of TM (green), TM-H1 (blue), TM-H2 (yellow) and TM-HS (red)Back to article page
