Park7 Antibody / DJ-1

Overview

Park7 Antibody / DJ-1 is a research-use-only Rabbit polyclonal (rabbit origin) Rabbit IgG directed against Park7 / DJ-1. It is supplied for interpretation-focused detection and comparative profiling in WB, IHC, ELISA. Reported localization context: Cytoplasmic, nuclear.

Key elements and design rationale

• Target context: This antibody is raised against A recombinant rat protein corresponding to amino acids A2-D189 was used as the immunogen for the Park7 antibody.. Epitope context matters because isoforms, processing, and post-translational modifications can change what is accessible in a given assay.
• Format: Antigen affinity purified. Format influences background and compatibility with different detection chemistries; conjugated formats (when present) can simplify multiplexing and reduce reliance on secondary reagents.
• Species reactivity: Rat, Mouse. Cross-species performance can vary with sequence divergence and epitope conservation, so interpretation should be anchored with appropriate biological controls.
• Localization: Cytoplasmic, nuclear. Subcellular compartment context can help guide expectations in imaging assays and informs fractionation-based comparisons in lysate workflows.
• Applications: WB, IHC, ELISA. These indicate assay contexts where the antibody is commonly applied; actual performance depends on sample type and processing.

Polyclonal reagents can differ in how they recognize epitope features. Monoclonal antibodies often provide more consistent epitope targeting across lots, while polyclonal preparations may broaden recognition across related epitope variants.

Biological background

Park7 / DJ-1 refers to the gene/protein target stated in the product record. Protein targets can exhibit context-dependent expression, regulated turnover, isoform diversity, and post-translational modifications that affect apparent molecular weight and epitope accessibility.

Research relevance and current trends

• Integrating antibody-based detection with single-cell and spatial atlasing efforts to connect RNA programs with protein-level abundance and localization in defined cell states.
• Expanding multiplexed imaging and high-content screening, where reagent specificity, cross-reactivity risk, and channel design (including direct conjugates) become central to interpretation.
• Growing emphasis on reproducibility and application-specific validation frameworks (e.g., genetic perturbation controls, orthogonal measurements, and independent antibody strategies) when drawing mechanistic conclusions.

Common research applications

• Western blot (WB): commonly used to compare relative abundance/size (e.g., band intensity or mobility shifts) between conditions.
• Immunohistochemistry (IHC): commonly used to compare tissue- and cell-type–specific expression patterns in situ.
• ELISA: commonly used to compare quantitative comparison of target levels across samples (matrix-dependent).

Interpretation typically focuses on relative differences (presence/absence, fold-changes, compartment shifts, or population-level shifts) rather than absolute quantitation. When signal changes are observed, they may reflect altered expression, altered localization/trafficking, changes in modification state, or differences in sample composition; orthogonal readouts and appropriate controls help distinguish these possibilities.

Application details (record-specific): Western Blot: 0.5-1ug/ml,IHC (FFPE): 1-2ug/ml ELISA (Capture; recombinant rat protein): 0.1-0.5ug/ml (BSA-free format available)

Application notes (record-specific): Optimal dilution of the Park7 antibody should be determined by the researcher.

Notes for experimental interpretation

• Product description (record-specific): Parkinson disease (autosomal recessive, early onset) 7, also known as DJ1, is a protein which in humans is encoded by the PARK7 gene. PARK7 belongs to the peptidase C56 family of proteins. PARK7 is mapped to chromosome 1p36. It acts as a positive regulator of androgen receptor-dependent transcription. It is also involved in tumorigenesis and in maintaining mitochondrial homeostasis. This gene may also function as a redox-sensitive chaperone, as a sensor foroxidative stress, and it apparently protects neurons against oxidative stress and cell death. It has been found that PARK7 mutations that impair transcriptional coactivator function can render dopaminergic neurons vulnerable to apoptosis and may contribute to the pathogenesis of Parkinson disease.
• Potential confounders: isoforms, proteolytic processing, and PTMs can change epitope presentation and apparent size; fixation/denaturation state can also expose or mask epitopes. Species differences near the epitope may affect cross-reactivity.
• Control concepts: include genetic perturbation (KO/KD) or overexpression comparisons, orthogonal measurement (e.g., transcript or proteomics), and independent antibody/epitope strategies. For conjugated reagents, include staining-only/background controls appropriate to the detection chemistry.

Immunogen/epitope context is described as: A recombinant rat protein corresponding to amino acids A2-D189 was used as the immunogen for the Park7 antibody.. Monoclonal and polyclonal formats differ in epitope breadth; this can influence sensitivity to sequence variants, isoforms, or PTM-dependent recognition.
