Overview
Anti-Bombesin Receptor 1 (NMBR) Antibody is an antibody targeting BB1R, Neuromedin B receptor, Neuromedin-B-preferring bombesin receptor Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IC, IF, IHC, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: BB1R, Neuromedin B receptor, Neuromedin-B-preferring bombesin receptor (also reported as BB1R, Neuromedin B receptor, Neuromedin-B-preferring bombesin receptor).
- Immunogen/epitope region: 3rd intracellular loop.
- Homology note: Mouse, dog - identical; rat - 15/16 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, 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
Bombesin receptor 1 (BB1) is a member of a family of receptors that binds the 14 amino acid peptide bombesin. Bombesin was initially isolated from frog skin and it was later established that mammals express endogenous bombesin-like peptides such as gastrin-releasing peptide (GRP) and neuromedin B (NMB), 27 and 10 amino acid homologues, respectively.1BB1 is the preferred receptor for NMB (therefore it is also known as NMB receptor) while BB2 is the preferred receptor for GRP.2 BB3 was the third member of the bombesin family of receptors to be cloned based upon its sequence similarity to BB1 and BB2.1 The affinity of BB3 for bombesin is lower than that of the BB1 and BB2 receptors, as are its affinities for NMB and GRP. This suggests that the endogenous mammalian ligand for the BB3 receptor remains to be identified.All three bombesin receptors are members of the 7-transmembrane domain, G protein-coupled receptor (GPCR) superfamily.
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.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
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-BR004.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
