Species reactivity (as provided): Human, Mouse, Rat.

Key elements and design rationale

• Target: DDX5 — selectivity and interpretation should be considered in the context of isoforms, post-translational modifications, and related family members when applicable.
• Format: Antigen affinity purified — format can influence background, multiplexing compatibility, and downstream detection strategies.
• Antibody identity: Mouse, Monoclonal (mouse origin), clone 3F9, isotype Mouse IgG2b — these attributes help align secondary reagents and controls (e.g., isotype-matched controls) with your assay design.
• Product notes (from provided description): DDX5 (DEAD/H BOX 5), also known as HLR1 or G17P1, is an enzyme that in humans is encoded by the DDX5 gene. The p68 protein is a proliferation-associated nuclear antigen first identified through its highly specific cross-reaction with the simian virus 40 tumor antigen (Iggo et al., 1989). Subsequently, homology to eukaryotic translation initiation factor was found, and amino acid sequence blocks characteristic of a large superfamily of proteins with putative helicase activity were demonstrated. Brody et al. (1995) confirmed that this gene is located on chromosome 17 in the region of the BRCA1 gene at 17q21. By immunoprecipitation analysis, Caretti et al. (2006) found that p68, p72 (DDX17), and the noncoding RNA SRA (SRA1) associated with MYOD (MYOD1) in MYOD-transfected HeLa cells.

Where multiple assay formats are possible, align the antibody format, host/isotype, and listed applications with your detection system and controls to support clear interpretation of signal.

Research relevance and current trends

• Higher-plex and spatially resolved readouts (e.g., multiplex IF/IHC, spatial omics) are increasing demand for well-characterized primary antibodies with clearly stated host/isotype and labeling strategies.
• Genetic perturbation controls (knockout/knockdown) and orthogonal measurements (e.g., RNA vs protein) are commonly used to strengthen target attribution when interpreting antibody-derived signals.
• Reproducibility initiatives emphasize transparent reporting of antibody identity (clone, host, isotype) and experimental context to improve cross-study comparability.

Common research applications

• WB: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• IHC-P: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• IHC-F: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• IF: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• FACS: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• Typical workflow themes: Western blot validation, IHC on FFPE tissue, IF/ICC localization, Flow cytometry staining, Specificity controls.
• Workflow notes: Validate DDX5 by Western blot in cell/tissue lysates (include controls), Detect DDX5 by IHC in FFPE tissue sections (optimize antigen retrieval + dilution), Detect DDX5 localization by IF/ICC in cultured cells (optimi…

When comparing conditions, consistent sample processing and appropriate negative/positive controls support interpretation of qualitative localization differences and quantitative abundance changes.

Notes for experimental interpretation

• Isoforms and post-translational modifications may shift apparent molecular weight or epitope accessibility, especially across cell states or treatments.
• Species and tissue context can affect sequence conservation, expression level, and background binding; predicted reactivity should be verified in your sample.
• Control concepts include isotype-matched controls, secondary-only controls (for indirect detection), and genetic/orthogonal controls (e.g., KO/KD, independent antibodies, or RNA measurements) when feasible.

Monoclonal and polyclonal antibodies can differ in epitope recognition breadth and lot-to-lot characteristics; consider clonality and clone information (when provided) alongside your assay requirements. Conjugated formats may simplify detection but can change background and multiplexing behavior compared with unconjugated primaries.

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).
