DTX46 Antibody

What is DTX46 Antibody and what cellular functions does its target protein regulate?

DTX46 Antibody targets the Deltex-46 protein, which belongs to the Deltex family of E3 ubiquitin ligases. Similar to the well-characterized Deltex-1 (DTX1), which is an approximately 75 kDa cytoplasmic and nuclear ubiquitin ligase, DTX46 interacts with the Notch signaling pathway and regulates Notch-induced gene transcription. The antibody enables researchers to study this protein's involvement in critical cellular processes including differentiation, proliferation, and apoptosis. Like other Deltex family members, DTX46 contains WWE domains and a RING-type zinc finger domain that are essential for its ubiquitin ligase activity and protein-protein interactions . Understanding these structural elements provides insight into experimental design when selecting antibody epitopes for specific research applications.

Which experimental techniques can effectively utilize DTX46 Antibody?

DTX46 Antibody can be effectively employed in multiple experimental techniques, including:

• Western blotting (WB): For detection of DTX46 protein in cell lysates, typically appearing as a specific band at the expected molecular weight. Based on related Deltex antibody performance, optimal dilutions range from 1:500 to 1:2000, with detection using appropriate HRP-conjugated secondary antibodies .

• Immunocytochemistry (ICC): For visualization of DTX46 cellular localization using fluorescently-tagged secondary antibodies. Recommended dilutions typically start at 5-10 μg/mL with fixation and permeabilization protocols similar to those used for DTX1/DTX4 antibodies .

• Flow cytometry: For quantitative analysis of DTX46 expression in cell populations. This requires cell fixation with paraformaldehyde and permeabilization with saponin or alternative agents to access intracellular proteins .

• Immunoprecipitation (IP): For isolation of DTX46 protein complexes to study binding partners and post-translational modifications.
  Each application requires specific optimization of antibody concentration, incubation time, and buffer conditions to achieve optimal signal-to-noise ratios.

How should DTX46 Antibody be stored and handled to maintain optimal activity?

To maintain optimal activity of DTX46 Antibody, researchers should follow these evidence-based storage and handling guidelines:

• Storage temperature: Store at -20°C to -70°C for long-term stability (up to 12 months from receipt date). For short-term storage (up to 1 month), 2-8°C is acceptable under sterile conditions after reconstitution .

• Freeze-thaw cycles: Use a manual defrost freezer and avoid repeated freeze-thaw cycles, which can denature antibody proteins and reduce binding efficiency .

• Reconstitution: After reconstitution, the antibody maintains stability for approximately 6 months at -20°C to -70°C under sterile conditions .

• Working dilutions: Prepare only the required amount for immediate use and store the stock solution as recommended. For western blotting applications, determine optimal dilutions empirically for each experimental setup.

• Contamination prevention: Use sterile techniques when handling antibody solutions to prevent microbial contamination.
  Proper storage and handling significantly impact experimental reproducibility and reliability of results across different batches of experiments.

How can I validate the specificity of DTX46 Antibody in my experimental system?

Validating antibody specificity is critical for reliable research outcomes. For DTX46 Antibody, implement these validation approaches:

• Knockdown/knockout validation: Compare staining between wild-type cells and those with CRISPR/Cas9-mediated DTX46 knockout or siRNA-mediated knockdown. The specific band or staining pattern should disappear or be significantly reduced in knockdown/knockout samples.

• Peptide competition assay: Pre-incubate the antibody with excess purified DTX46 peptide (corresponding to the immunogen) before application to samples. Specific signals should be blocked or significantly reduced.

• Cross-reactivity assessment: Test reactivity against other Deltex family members (DTX1, DTX2, DTX3, DTX4) to ensure specificity, especially given the structural similarities between Deltex proteins. Similar to DTX1/DTX4 antibody testing, this can be performed using recombinant proteins or overexpression systems .

• Multiple antibody comparison: When possible, compare results using antibodies targeting different epitopes of the DTX46 protein to confirm consistent patterns.
  Document all validation results thoroughly to support the reliability of subsequent experimental findings.
