Fig. 4From: An auto-antibody identified from phenotypic directed screening platform shows host immunity against EV-A71 infectionCharacterization of 07-IgG1 using mass spectrum identification. A Mass spectrum identification of 07-IgG1 pull-down proteins could be HSA, β-actin, or ENO1. B ENO1, HSA, or β-actin recombinant protein was used in indirect ELISA with 07-IgG1. C EV-A71 patients’ sera were used to detect IgG against hENO1 protein. The levels of anti-ENO1 antibody were quantified by ELISA using 07-IgG1 as the standard antibody. **p < 0.001Back to article page
