Recombinant Antibody
Specificity
Z23 binds to the ZIKV soluble envelope (sE) protein, shown using ELISAs, SPR and kinetic competition assays (Wang et al, 2016). This mAb is highly specific for ZIKV, and was shown to exhibit no neutralisation activity against DENV-1 to DENV-4 virions, which are highly related to ZIKV. Z23 was shown to bind domain III of sE by cryo-electron microscopy. ZIKV has recently become a major global health concern, following a 2015 outbreak. Viral infection is associated with neurological complications and microencephaly.
Alternative Names
ZIKV sE; Zika virus soluble envelope protein; Zika virus envelope protein; ZIKV soluble envelope protein; ZIKV envelope protein; Zika virus sE protein; ZIKV sE protein; ZIKV sE; Z-23
UniProt
Immunogen
Anti-ZIKV mAbs were obtained from the sera and peripheral blood mononuclear cells of a ZIKV-infected patient.
Application Notes
Z23 was confirmed to bind ZIKV sE protein by ELISA, with an affinity of 0.44 uM shown by SPR (Wang et al, 2016). Using a FACS-based assay, it was shown that Z23 potently neutralised viral activity against infected C6/36 and Vero cells. In vivo, Z23 completely protected IFN receptor KO mice from ZIKV infection.

Note on publication
Describes the identification of several anti-ZIKV mAbs from the blood of a patient with ZIKV infection. The mAbs identified were characterised for antigen specificity using biochemical and biophysical methods, and a few of the mAbs found were crystallised with the ZIKV sE protein.
