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 55.7 kDa. The protein migrates as 60-70 kDa when calibrated against Star Ribbon Pre-stained Protein Marker 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 0.1 M Sodium citrate, pH5.5 with trehalose as protectant.

FAQ
- Product
What do “pre” and “post” refer to in the names of viral proteins?
In virology, “pre” refers to the conformation of a viral surface glycoprotein before fusion with the host cell membrane, while “post” refers to the conformation after membrane fusion and entry into the host cell. Both are naturally occurring states in the viral life cycle. Because the “pre” conformation represents a critical stage before viral entry, antibodies designed against this state often exhibit stronger neutralizing activity and are therefore more effective in preventing infection.
