| Description |
Recombinant Ebola Zaire Glycoprotein is a mucin like domain containing 181 amino acids was derived from Zaire Ebola Virus (strain Kikwit-95) gp mucin sequence produced in E. coli, and fused to a 6xHis tag at its C-terminus, having a molecular weight 38kDa.Ebola Zaire GP is purified by a proprietary chromatographic technique. |
| Protein Background |
Ebolavirus (EVD) belongs to the Filoviridae family of proteins which is comprised of a single-strand, non-infectious RNA genome. EVD genome is about 19,000 base pairs long and covers 7 genes in the order 3'-UTR-NP-VP35-VP40-GP-VP30-VP24-L-5'-UTR. There are 4 different ebolaviruses such as: Zaire (EBO-Z), Sudan (EBO-S), Cote dIvoire (EBO-CI) and Reston (EBO-R) that differ in amino acid sequence and location of where the gene overlaps. The EBOV glycoprotein is the only virally expressed protein above the virion surface. The EBOV glycoprotein is essential for virus attachment to host cell and fusion with target cell. Mucin like domain within Ebola virus glycoprotein contains multiple glycosylated amino acids. It has been shown that antibodies frequently develop against its mucin like domain. Recombinant mucin like domain is a suitable antigen to test specific antibodies from Ebola virus infected patients. |
| Expression host |
Escherichia Coli. |
| Stability |
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles. |
| Rapid Test Assay |
Each reaction contains 50 ug of partially purified thioredoxin-NP-27 fusion protein and varying amounts of Bovine EK. Reactions were incubated at 25°C for 16 hours and analyzed on a Coomassiestained 15% SDS gel. |
