- an hFc (IgG1)
Product overview
Recombinant Mouse GITR Ligand/TNFSF18 Protein is expressed in HEK293 cells with an hFc (IgG1) tag at the N-terminus. It contains amino acid residues Thr47-Ser173 (UniProt accession: Q7TS55).
Product Details
- Molecular Aliases
- TNFSF18; AITRL; TL6; GITRL; GITR Ligand
- Protein Length
- Thr47-Ser173
- Expression System
- HEK293
- Theoretical Molecular Weight
- The protein has a predicted MW of 41.8 kDa. Due to glycosylation, the protein migrates to 50-60 kDa based on Bis-Tris PAGE result.
- Purity
- > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
- Endotoxin
- Less than 1 EU per μg by the LAL method.
- Buffer / Formulation
- Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
- State
- Lyophilized
- Storage Conditions
- -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
- Reconstitution Advice
- Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.
Data Display
Mouse GITR Ligand on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
The purity of Mouse GITR Ligand is greater than 95% as determined by SEC-HPLC.
Background
Glucocorticoid-induced TNFR-related protein (TNFRSF18, GITR, CD357), expressed by T cells, and its ligand (TNFSF18, GITRL), expressed by myeloid populations, provide co-stimulatory signals that boost T cell activity. Due to the important role that GITR plays in regulating immune functions, agonistic stimulation of GITR is a promising therapeutic concept.
