Source

Human PD-1 Protein, His Tag (PD1-H522a) is expressed from human 293 cells (HEK293). It contains AA Leu 25 - Gln 167 (Accession # NP_005009.2).

Predicted N-terminus: Leu 25

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

This protein carries a polyhistidine tag at the C-terminus, and has a calculated MW of 16.8 kDa. The N-terminus Sequence Analysis is Leu 25. The reducing (R) protein migrates as 31-44 kDa when calibrated against Star Ribbon Pre-stained Protein Marker in SDS-PAGE due to glycosylation.

Endotoxin

Less than 0.01 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 PBS, pH7.4 with trehalose as protectant.
