Anti-Zika, Env (Clone ZIKA-4499)

≥1.0 mg/ml

Formulated in 0.015 M phosphate buffered saline (0.85% NaCl), pH 7.2 and contains 0.05% sodium azide. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.

Zika virus (ZIKV) infection during pregnancy is a global public health problem 1, linked causally to severe fetal abnormalities 2. Prophylactic antibodies may prove useful in treating pregnant patients or for designing epitope-specific vaccines 1. ZIKV is a mosquito transmitted flavivirus that encodes a single polyprotein with an ~11 kb positive-sense RNA open reading frame 1. The polyprotein is cleaved into seven non-structural (NS) proteins and three structural proteins (capsid (C), pre-membrane (prM), and envelope (E)). C forms a nucleocapsid. prM complexes with E to facilitate folding and prevent premature fusion to host membranes. E is responsible for viral assembly, attachment, entry, and fusion 1,3 and is a major target of neutralizing antibody research 3. Mature ZIKV virions incorporate 180 copies each of the E and M proteins 4,5.
