Source

Human Complement Receptor type 2 Protein, His Tag (CD2-H52H4) is expressed from human 293 cells (HEK293). It contains AA Ile 21 - Arg 971 (Accession # P20023-1).

Predicted N-terminus: Ile 21

Molecular Characterization
Other Tags and Version Biotin & Other Labeled Version

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 106.1 kDa. The protein migrates as 110-120 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background

Epstein-Barr virus (EBV), also designated human herpesvirus 4 (HHV-4), is a member of the herpesvirus family and is one of the most common human viruses. EBV binds to the cell surface receptor 2 (CD21/CR2) on human B cells using its major envelope glycoprotein 350 (gp350) and, as such, the EBV gp350 Envelope Protein, also designated the EBV envelope glycoprotein complex 250/350, is crucial in mediating the initial stages of EBV infection. The EBV gp350 Envelope Protein is expressed on virion envelope as well as EBV producer cells.
