A Schematic representation of the sandwich ELISA for selecting the positive clones of antibodies. B ELISA signal with various colonies of antibodies. Mix and Comm. indicates a mixed antibody prior to selection and a commercial anti-hMMP9 antibody, respectively. C SDS-PAGE analysis of #6 antibody after (+) or before (–) protein reducing through 100 mM DTT and heating. We displayed a cropped gel in Fig. 3C. The original gel was presented in Additional file 1: Fig. S6.
