Overview
Anti-B1 Bradykinin Receptor (BDKRB1) (extracellular) Antibody is an antibody targeting BK-1 receptor, BKRB1, B1R, BKR1 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IFC, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: BK-1 receptor, BKRB1, B1R, BKR1 (also reported as BK-1 receptor, BKRB1, B1R, BKR1).
- Immunogen/epitope region: Extracellular, 2nd loop..
- Homology note: Rat - 12 out of 13 amino acid residues identical Not recommended for human samples (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
Kinins are small peptides rapidly produced following tissue injury that serve as important modulators of inflammation and pain. In the periphery, the actions of kinins include vasodilatation, increased vascular permeability, stimulation of immune cells, and induction of pain. Kinins in the central nervous system (CNS) appear to initiate a similar cascade of events leading to neural tissue damage as well as long lasting disturbances affecting blood-brain barrier function.1Kinins such as Bradykinin (BK), Lys-BK, desArg9-BK, and Lys-desArg9-BK exert their action via two distinct receptors: the B1 Bradykinin receptor (BKRB1) and the B2 Bradykinin receptor (BKRB2).
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.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
- Flow cytometry (direct/indirect): quantify target-positive populations and shifts in expression across subsets.
- Live cell imaging (LCI): support extracellular-epitope detection on non-permeabilized cells when appropriate.
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-BR013.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
