  • (Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
  • Based on the SEQUEST from database of E.coli host and target protein, the LC-MS/MS Analysis result of CSB-EP360986EFA could indicate that this peptide derived from E.coli-expressed Epstein-Barr virus (strain B95-8) (HHV-4) (Human herpesvirus 4) BLLF1.

Form 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.
Buffer If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution 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.

Protein 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
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
(From Uniprot)
Initiates virion attachment to host B-lymphocyte cell, leading to virus entry. Acts by binding to host CR2 at the surface of B-lymphocytes, facilitating the binding of viral glycoprotein gp42 to HLA class II molecules. Attachment triggers virion-host membrane fusion and invasion of the host cell.
Gene References into Functions
  1. The similar distribution of gp350/220 variants in nasopharyngeal carcinoma, EBV-associated gastric carcinoma and healthy donors suggest that gp350/220 variations are geographically restricted rather than tumor-specific polymorphisms. PMID: 22038027
  2. gp350 mainly exerts its functions after the internalization step, presumably during release of the viral capsid from the endosomal compartment, and that CD21-dependent but also CD21-independent molecular mechanisms are involved in this process. PMID: 19889766
  3. X-ray structure of the highly glycosylated gp350; defined the CR2 binding site on gp350, deglycosylated gp350 bound CR2 similarly to the glycosylated form, suggesting that glycosylation is not important for receptor binding PMID: 17072314
  4. These site-directed mutations identified a novel negatively charged complement receptor type 2-binding surface described by residues Glu-21, Asp-22, Glu-155, Asp-208, Glu-210, and Asp-296. PMID: 18786993
Subcellular Location Virion membrane; Single-pass membrane protein. Host membrane; Single-pass membrane protein. Note=Most abundant component of the viral envelope.
