Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: A synthetic peptide corresponding to a sequence at the N-terminus of human GPCR LGR8.
- Molecular weight context: reported MW: 86 kDa; calculated MW: 35883 MW
- Reactivity: Human
- Applications: Flow Cytometry, 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
Annexin A4; relaxin family peptide receptor 2. Relaxin/insulin-like family peptide receptor 2, also known as RXFP2, is a human G-protein coupled receptor. It is mapped to 13q13.1. This gene encodes a member of the GPCR (G protein-coupled, 7-transmembrane receptor) family. Mutations in this gene are associated with cryptorchidism. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. Functional note: Receptor for relaxin. The activity of this receptor is mediated by G proteins leading to stimulation of adenylate cyclase and an increase of cAMP. May also be a receptor for Leydig insulin-like peptide (INSL3). Reported localization: Cell membrane; Multi-pass membrane protein. Expression/tissue context: Expressed mainly in the brain, kidney, muscle, testis, thyroid, uterus, peripheral blood cells and bone marrow.
Research relevance and current trends
- Endocrine System: Researchers commonly examine how RXFP2 (Annexin A4) relates to this theme using model systems and orthogonal readouts.
- G Protein Signaling: Researchers commonly examine how RXFP2 (Annexin A4) relates to this theme using model systems and orthogonal readouts.
- More Gpcr: Researchers commonly examine how RXFP2 (Annexin A4) relates to this theme using model systems and orthogonal readouts.
Common research applications
- Western blotting: compare relative RXFP2 (Annexin A4) levels across conditions; band patterns may reflect isoforms and processing.
- Flow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.
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.
