Overview
Anti-RXFP2 (extracellular) Antibody is an antibody targeting Relaxin receptor 2, G-protein coupled receptor affecting testicular descent, Leucine-rich repeat-containing G-protein coupled receptor 8, GPR106, GREAT, LGR8, INSL3R 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: Relaxin receptor 2, G-protein coupled receptor affecting testicular descent, Leucine-rich repeat-containing G-protein coupled receptor 8, GPR106, GREAT, LGR8, INSL3R (also reported as Relaxin receptor 2, G-protein coupled receptor affecting testicular descent, Leucine-rich repeat-containing G-protein coupled receptor 8, GPR106, GREAT, LGR8, INSL3R).
- Immunogen/epitope region: 2nd extracellular loop.
- Homology note: Rat - identical (informative for cross-species interpretation).
- Species reactivity (as provided): Rat, Mouse.
- Specificity statement (as provided): Not recommended for use on human samples..
- 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.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
Relaxin (RXFP) peptides are members of a family of peptide hormones, structurally related to insulin, which act on a group of four G-protein-coupled receptors known as Relaxin family peptide receptors (RXFPs): RXFP1-4.The RXFP2 (also called LGR8) structure contains 7-transmemebrane spanning domains, at least two binding sites: a long extracellular sequence with a high affinity site containing 10 leucine-rich repeat region and a lower-affinity site in an extracellular loop of a transmembrane region. In addition, the receptor contains an N-terminal ectodomain that acts as a site of primary ligand binding1,2. RXFP2 is also the native receptor for insulin-like peptide 3 (INSL3)1,2.
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-RR012.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
