- SynonymFAM171B,KIAA1946,NPD019
- SourceHuman FAM171B, His Tag (FAB-H5220) is expressed from human 293 cells (HEK293). It contains AA Glu 33 - Thr 355 (Accession # AAH60872).Predicted N-terminus: Glu 33Request for sequence
- Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 36.8 kDa. The protein migrates as 45-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>92% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
