Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

The recombinant HHV-2 Envelope glycoprotein E protein is a cell-free system in vitro E.coli expressed protein (Full Length of Mature Protein). In cell-free systems, synthesis of the protein can be carried out in vitro using extracts of whole cells that are compatible with translation. These cell extracts contain all the molecules and enzymes that are needed to transcribe, translate, and post-translationally modify the recombinant protein. With additional supplements of cofactors, Envelope glycoprotein E proteins can be formed in a few hours. However, this system may not be applicable for the large-scale production of recombinant proteins. Advantages of this system include that proteins can be synthesized without cell culturing; also, it is possible to express many proteins together.

HSV-2 gE is important for cell-to-cell transmission and virus-induced cell fusion. It acts as an immune evasion molecule by attaching the IgG Fc domain. HSV-2 gE protects the virus from antibody and complement neutralization in a synergistic manner with gC. Antibodies generated by gE immunization prevented gE-mediated IgG Fc binding and cell-to-cell dissemination. As a result, gE is a potential antigen for inclusion in a multivalent subunit vaccination aimed at blocking HSV-2 immune evasion.

Target Background

In epithelial cells, the heterodimer gE/gI is required for the cell-to-cell spread of the virus, by sorting nascent virions to cell junctions. Once the virus reaches the cell junctions, virus particles can spread to adjacent cells extremely rapidly through interactions with cellular receptors that accumulate at these junctions. Implicated in basolateral spread in polarized cells. In neuronal cells, gE/gI is essential for the anterograde spread of the infection throughout the host nervous system. Together with US9, the heterodimer gE/gI is involved in the sorting and transport of viral structural components toward axon tips.; The heterodimer gE/gI serves as a receptor for the Fc part of host IgG. Dissociation of gE/gI from IgG occurs at acidic pH. May thus be involved in anti-HSV antibodies bipolar bridging, followed by intracellular endocytosis and degradation, thereby interfering with host IgG-mediated immune responses.
