Ebolavirus EBOV(subtype Zaire,strain Kikwit-95) Envelope Glycoprotein (GP) (Ebolavirus EBOV(subtype Zaire,strain Kikwit-95) GP) Ile 33 - Asp 637 (Accession # AAQ55048.1) was produced in human 293 cells (HEK293) at ACROBiosystems.

Molecular Characterization

Ebolavirus EBOV(subtype Zaire,strain Kikwit-95) GP, containing GP1 and GP2, is fused with a polyhistidine tag at the C-terminus, and has a calculated MW of 67 kDa. The predicted N-terminus is Ile 33. DTT-reduced Protein migrates as 21-23 kDa (GP2-delta) and 110-120 kDa (GP1) in SDS-PAGE .


Less than 1.0 EU per μg of the Ebolavirus EBOV(subtype Zaire,strain Kikwit-95) GP by the LAL method.


>85% as determined by SDS-PAGE.


Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Mannitol or Trehalose are added as protectants before lyophilization.

Ebolavirus EBOV(subtype Zaire,strain Kikwit-95) Envelope Glycoprotein (GP)
The purity of Ebolavirus EBOV(subtype Zaire,strain Kikwit-95) GP was determined by DTT-reduced (+) SDS-PAGE and staining overnight with Coomassie Blue.


EBOV encodes seven structural proteins: nucleoprotein (NP), polymerase cofactor (VP35), (VP40), GP, transcription activator (VP30), VP24, and RNA polymerase (L). GP protein contains 160-kDa envelope-attached glycoprotein (GP) and a 110 kDa secreted glycoprotein (sGP). GP is a class I fusion protein which assembles as trimers on viral surface and plays an important role in virus entry and attachment. Mature GP is a disulfide-linked heterodimer formed by two subunits, GP1 and GP2, which are generated from the proteolytical process of GP precursor (pre-GP) by cellular furin during virus assembly . GP1 is responsible for binding to the receptor(s) on target cells. Interacts with CD209/DC-SIGN and CLEC4M/DC-SIGNR which act as cofactors for virus entry into the host cell. GP2 acts as a class I viral fusion protein. GP1,2 mediates endothelial cell activation and decreases endothelial barrier function. sGP seems to possess an anti-inflammatory activity as it can reverse the barrier-decreasing effects of TNF alpha.
