Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein indeionized sterile water to a concentration of 0.1-1.0 mg/mL.Aliquot for long-term storage at -80°C. Solubilize for 60 minutes at room temperature with occasional gentle mixing. Avoid vigorous shaking or vortexing.
Tag

Relevance
Glycoprotein N): Glycoprotein N and glycoprotein C interact with each other and are present at the surface of the virion (Probable). Glycoprotein N probably locks the Gn-Gc complex in a prefusion state. Glycoprotein N and glycoprotein C are able to attach the virion to host cell receptors (Probable). This attachment induces virion internalization predominantly through clathrin-dependent endocytosis. ; Glycoprotein C): Glycoprotein C and glycoprotein N interact with each other and are present at the surface of the virion. The spikes at the surface of the virion are formed by an N-terminal extension of glycoprotein C. Glycoprotein N and glycoprotein C are able to attach the virion to host cell receptors (Probable). This attachment induces virion internalization predominantly through clathrin-dependent endocytosis. Class II fusion protein that promotes fusion of viral membrane with host endosomal membrane after endocytosis of the virion. Exposure of the glycoprotein spikes to potassium is necessary for the conformational change leading to fusion.

Notes
The VLPs are expressed from human 293 cells (HEK293).Mix the sample gently by repeatedly pipetting it up and down. Do not vortex.Repeated freezing and thawing is not recommended.Store the protein at -20°C/-80°C upon receiving it, and ensure to avoid repeated freezing and thawing, otherwise, it will affect the protein activity. The immunization strategy should be optimized (antigen dose, regimen and adjuvant).
Lyophilized from a 0.2 um sterile filtered PBS, 6% Trehalose, pH 7.4.
Purity
The purity information is not available for VLPs proteins.
Storage
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.
