Key elements and design rationale
- Target: PRPF31 — Transcription factor E2F3 (tumor necrosis factor receptor superfamily, member 18). Alternative names: Tumor necrosis factor receptor superfamily member 18; Glucocorticoid-induced TNFR-related protein; CD357; Tnfrsf18; Gitr
- Antibody format: Polyclonal; Rabbit IgG
- Species context: Host: Rabbit, Reactivity: Human,Mouse,Rat
- Purification: Immunogen affinity purified.
- Immunogen: E.coli-derived human PRPF31 recombinant protein (Position: K73-K488).
- Molecular weight context: observed 60 kDa, calculated 26000 MW (reported)
- Provided application(s): WB, IHC, IF, ICC, Flow, ELISA
These attributes help contextualize how the antibody is commonly selected (host/clonality/isotype/label) and how signals are interpreted across sample types and assay formats.
Biological background
Function: 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.
Cellular localization: Cell membrane. Single-pass type I membrane protein. Secreted.
Tissue details: Detected in thymus and in activated splenocytes.
Background: PRP31 pre-mRNA processing factor 31 homolog (S. cerevisiae), also known as PRPF31, is a protein which in humans is encoded by the PRPF31 gene. This gene encodes a component of the spliceosome complex and is one of several retinitis pigmentosa-causing genes. When the gene product is added to the spliceosome complex, activation occurs.
Cross reactivity: No cross-reactivity with other proteins.
Research relevance and current trends
- Quantitative and spatial profiling: expression patterns are increasingly studied across cell states using multiplex imaging and omics-informed validation.
- Isoforms and post-translational modifications: researchers often evaluate how isoform composition and PTMs can shift apparent molecular weight or localization.
- Context-aware interpretation: comparative studies commonly include perturbations (stimulation, inhibition, genetic models) to relate target changes to pathway behavior.
Common research applications
- Western blot (WB): compare relative target abundance and apparent size shifts (e.g., isoforms/PTMs) across conditions.
- Immunohistochemistry (IHC): assess distribution across tissue compartments and compare staining patterns between groups.
- Immunofluorescence / ICC: evaluate subcellular localization and co-localization with compartment markers.
- Flow cytometry: quantify target-positive populations and compare shifts after stimulation or differentiation.
Across these uses, researchers typically interpret changes in signal as relative differences between matched sample groups, considering sample preparation and biological context.
Notes for experimental interpretation
- Apparent molecular weight can vary due to isoforms, proteolysis, glycosylation, phosphorylation, and sample preparation differences.
- Species reactivity and epitope conservation can influence observed signal patterns, especially in cross-species studies.
- Control concepts: include appropriate negative controls (e.g., isotype controls where relevant) and, when feasible, genetic or orthogonal controls (KO/KD, peptide competition, or independent assays) to support interpretation.
For antibody reagents, monoclonal antibodies are often chosen for epitope consistency across lots, while polyclonals may recognize multiple epitopes and can show different background characteristics depending on context.
