Synonyms

CD70, CD27LG, TNFSF7, TNFSF7G, CD27L

Source

Human CD27 Ligand, Llama IgG2b Fc Tag (CDL-H5255) is expressed from human 293 cells (HEK293). It contains AA Ser 52 - Pro 193 (Accession # NP_001243.1).

Predicted N-terminus: Glu

Molecular Characterization

This protein carries a llama IgG2b Fc tag at the N-terminus.

The protein has a calculated MW of 75.5 kDa. The protein migrates as 140-160 kDa under non-reducing (NR) condition (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 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5 with trehalose as protectant.
