Key elements and design rationale
- Target: MDR1 (reported localization: Cytoplasm, cell membrane).
- Antibody identity: Polyclonal (rabbit origin); Rabbit IgG.
- Conjugate/label: Unconjugated (affects detection chemistry and multiplex compatibility).
- Format: Antigen affinity purified.
- Species reactivity: Human.
- Listed applications: WB, FACS, IHC-P, Direct ELISA (refer to on-page specifications for application-specific guidance).
Biological background
P-GP, also called ABCB1 or PGY1, is a glycoprotein that in humans is encoded by the ABCB1 gene. It is mapped to 7q21.12. P-GP is a well-characterized ABC-transporter (which transports a wide variety of substrates across extra- and intracellular membranes) of the MDR/TAP subfamily. It is an important protein of the cell membrane that pumps many foreign substances out of cells. More formally, it is an ATP-dependent drug efflux pump with broad substrate specificity. P-GP is an ATP-dependent drug efflux pump forxenobiotic compounds with broad substrate specificity. It is responsible for decreased drug accumulation in multidrug-resistant cells and often mediates the development of resistance to anticancer drugs. This protein also functions as a transporter in the blood-brain barrier.
Research relevance and current trends
- Comparative expression profiling across cell types, tissues, or perturbations (e.g., drug treatment, genetic editing, or differentiation).
- Subcellular localization and trafficking studies, including co-localization with pathway markers in microscopy-based assays.
- Integration of protein-level measurements with transcriptomics or proteomics to relate abundance to regulation and phenotype.
Common research applications
- Western blotting: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
- Flow cytometry: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
- Immunohistochemistry: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
- ELISA: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
Interpretation should account for antibody-dependent factors such as epitope accessibility, isoforms, and sample preparation differences across workflows.
Notes for experimental interpretation
- Isoforms and PTMs: many targets have multiple isoforms and post-translational modifications that can shift apparent signal or localization; interpret bands/signals accordingly.
- Epitope context: binding can depend on protein conformation and sample processing; region information in the title/immunogen can help anticipate what may be detected.
- Species differences: predicted or validated reactivity may vary by ortholog sequence and sample context; confirm in your model system.
- Control concepts: include negative controls (no-primary/isotype), and where possible genetic controls (KO/KD) or independent antibodies to strengthen conclusions.
Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
