Fig. 3From: DNA aptamer against EV-A71 VP1 protein: selection and applicationThe dissociation constant (Kd) values of aptamer candidates for EV-A71 VP1 protein, were measured by ELISA. The Kd value of V7 (a). The Kd value of V11 (b). The Kd value of V21 (c). The values of OD450 and Kd represent the mean ± SD of three independent experimentsBack to article page
