Human Serpin H1, His Tag (SE1-H5224) is expressed from human 293 cells (HEK293). It contains AA Ala 19 - Leu 418 (Accession # P50454-1).
Predicted N-terminus: Ala 19
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 45.5 kDa. The protein migrates as 47 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Human Serpin H1, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
Serpin H1 is also known as SERPINH1, 47 kDa heat shock protein (HSP47), Collagen-binding protein (Colligin), Arsenic-transactivated protein 3 (AsTP3), which belongs to the serpin family. SERPINH1 binds specifically to collagen. SERPINH1 / HSP47 could be involved as a chaperone in the biosynthetic pathway of collagen.
