Fig. 4From: Optimization of Zika virus envelope protein production for ELISA and correlation of antibody titers with virus neutralization in Mexican patients from an arbovirus endemic regionELISA assays to assess the reactivity of human sera from patients in a ZIKV endemic region of Mexico. Sera from Zika patients from Mexico (blue) and sera obtained from healthy donors (who should have less or no previous flaviral exposure (red). a. The graph of ZIKV Env-CD4 vs commercial Env OD405 against sera dilutions. b. The graph shows the endpoint reciprocal titers for ZIKV patients using Env-CD4 and commercial Env proteins. P value (< 0.0001) was determined by pairwise t-testsBack to article page
