Overview
Anti-LGI1 Antibody is an antibody targeting Leucine-rich glioma-inactivated protein 1, Epitempin-1, EPT Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Leucine-rich glioma-inactivated protein 1, Epitempin-1, EPT (also reported as Leucine-rich glioma-inactivated protein 1, Epitempin-1, EPT).
- Immunogen/epitope region: LRRCT domain.
- Homology note: Mouse - identical; human - 12/13 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Rat, Mouse.
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
- Conjugate/format: Unconjugated (may affect detection channel and background).
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
The leucine-rich glioma inactivated (LGI) gene subfamily contains four highly conserved members (LGI1, 2, 3 and 4), which have been described in human, mouse and other mammalians. LGI1 is mainly expressed in the dentate gyrus and the CA3 field of the hippocampus1.The predicted structure of the LGI1 protein comprises, starting from the N-terminal, a signal peptide, four leucine-rich repeats (LRR) flanked on both sides by conserved cysteine clusters, and seven copies of a repeat of about 45 residues, named EPTP or EAR, probably forming a β-propeller structural domain. Both LRR and β-propeller domains mediate protein-protein interactions, each motif defining a distinct family of proteins.LGI1 is associated with a post-synaptic complex containing PSD-95 and ADAM22, a receptor associated with the post-synaptic membrane.
Research relevance and current trends
- Comparing target expression across perturbations, genotypes, or treatment conditions.
- Interpreting localization shifts alongside pathway or phenotypic readouts.
- Using orthogonal controls (KO/KD, peptide competition, isotype concepts) to support conclusions.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Provided control suggestions: Negative control: BLP-LR041.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
