Overview
Anti-BMPR1A (extracellular) Antibody is an antibody targeting Bone Morphogenetic Protein Receptor Type-1A, Activin Receptor-Like Kinase 3, ALK3, Serine/Threonine-Protein Kinase Receptor R5, SKR5, CD292 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IFC, IHC, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Bone Morphogenetic Protein Receptor Type-1A, Activin Receptor-Like Kinase 3, ALK3, Serine/Threonine-Protein Kinase Receptor R5, SKR5, CD292 (also reported as Bone Morphogenetic Protein Receptor Type-1A, Activin Receptor-Like Kinase 3, ALK3, Serine/Threonine-Protein Kinase Receptor R5, SKR5, CD292).
- Immunogen/epitope region: Extracellular, N-terminus..
- Homology note: Rat, Human - 15 out of 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
Bone morphogenic protein receptor type 1A (BMPR1A), also known as activin receptor-like kinase 3 (ALK3), and CD292, is a type I receptor within the Transforming Growth Factor-beta (TGF-β) receptor superfamily.1The TGF-β family of ligands has 33 human members, encoding TGF-β isoforms, bone morphogenetic proteins (BMPs), growth and differentiation factors (GDFs), activins, inhibins, nodal, and anti-Müllerian hormone (AMH). The TGF-β superfamily ligands regulate cellular function through seven type I TGF-β superfamily receptors (ALK (Activin like kinase)-1-7) and five type II TGF-β superfamily receptors (TβRII, ActRII, ActRIIB, AMHRII, and BMPRII). Type I (RI) and type II (RII) TGF-β superfamily receptors are serine/threonine kinases that form a complex together, and upon ligand binding the type II receptor phosphorylates the type I receptor to induce downstream signalling.1BMPR1A binds several of the TGF-β family ligands including BMP2, BMP4, GDF5, and GDF6, and is expressed in various tissues throughout the body, reflecting its diverse roles in development and homeostasis.
Research relevance and current trends
- Profiling immune-marker expression across cell subsets with single-cell or flow-based readouts.
- Connecting receptor/ligand levels to activation state and cytokine programs.
- Applying genetic perturbation or orthogonal assays to support specificity and interpretation.
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.
- 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-BR043.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
