Source
Human OX40 Ligand, Fc Tag, premium grade (OXL-H5266) is expressed from human 293 cells (HEK293). It contains AA Gln 51 - Leu 183 (Accession # P23510-1).
Predicted N-terminus: Pro
It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.
Molecular Characterization
This protein carries a human IgG1 Fc tag at the N-terminus.
The protein has a calculated MW of 74.0 kDa. The protein migrates as 140-200 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 0.01 EU per μg by the LAL method / rFC method.
Sterility
Negative
Mycoplasma
Negative
Purity
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
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.
