Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E. coli-derived human TNFRSF18 recombinant protein (Position: Q26-P162). (reported region: Q26-P162).
- Molecular weight context: reported MW: 26 kDa; calculated MW: 26000 MW
- Reactivity: Human
- Applications: ELISA, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
Transcription factor E2F3; TNF receptor superfamily member 18. Tumor necrosis factor receptor superfamily member 18 (TNFRSF18), also called GITR or AITR is a protein that in humans is encoded by the TNFRSF18 gene. It is mapped to 1p36.33. This gene encodes a member of the TNF-receptor superfamily. The encoded receptor has been shown to have increased expression upon T-cell activation, and it is thought to play a key role in dominant immunological self-tolerance maintained by CD25 (+)CD4 (+) regulatory T cells. Knockout studies in mice also suggest the role of this receptor is in the regulation of CD3-driven T-cell activation and programmed cell death. Three alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported. Functional note: Receptor for TNFSF18. Seems to be involved in interactions between activated T-lymphocytes and endothelial cells and in the regulation of T-cell receptor-mediated cell death. Mediated NF-kappa-B activation via the TRAF2/NIK pathway. Reported localization: Isoform 1: Cell membrane; Single-pass type I membrane protein. Expression/tissue context: Expressed in lymph node, peripheral blood leukocytes and weakly in spleen.

- ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
