This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 63.7 kDa. The protein migrates as 90 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
The protein is designed as a trimer.
Less than 1.0 EU per μg by the LAL method / rFC method.
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in 0.1 M Sodium citrate, pH5.5 with trehalose as protectant.
