Human CD27 Ligand Protein, His,Flag Tag (CDL-H52Da) is expressed from human 293 cells (HEK293). It contains AA Ser 52 - Pro 193 (Accession # P32970-1) trimer Design.
Predicted N-terminus: His
Molecular Characterization
This protein carries a polyhistidine tag at the N-terminus, followed by a flag tag.
The protein has a calculated MW of 49.3 kDa. The protein migrates as 50-60 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) 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.
>90% as determined by SEC-MALS.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
