DOX1 Antibody

What is DOX1 Antibody and what is its target specificity?

DOX1 Antibody (product code CSB-PA830255XA01DOA) is a polyclonal antibody developed against the DOX1 protein (UniProt accession Q9SGH6) found in Arabidopsis thaliana (Mouse-ear cress). This antibody is typically available in both concentrated (0.1ml) and ready-to-use (2ml) formats for research applications . The antibody is designed to specifically recognize epitopes on the DOX1 protein in plant tissue samples, making it valuable for researchers studying protein expression, localization, and function in this model organism.

Unlike therapeutic antibodies that may generate anti-drug antibodies (ADAs) in patients, research antibodies like DOX1 Antibody are specifically engineered for consistent laboratory use in detection applications . When selecting this antibody for your research, consider its validated applications, which typically include Western blotting, immunoprecipitation, and possibly immunofluorescence techniques.

What are the recommended storage and handling conditions for DOX1 Antibody?

For optimal performance and longevity of DOX1 Antibody, researchers should follow these evidence-based storage and handling protocols:

• Store the concentrated antibody (0.1ml format) at -20°C for long-term storage

• Store the ready-to-use antibody (2ml format) at 4°C for up to one month

• Avoid repeated freeze-thaw cycles by preparing working aliquots upon first thaw

• Add carrier proteins (such as BSA at 1-5%) if diluting the concentrated antibody

• Use sterile techniques when handling to prevent microbial contamination

These recommendations align with standard protocols for research-grade antibodies to maintain their binding specificity and sensitivity over time. When preparing working dilutions, use high-quality buffers appropriate for your specific application to prevent degradation or aggregation that could compromise experimental results.

• Western blot analysis: Verify single band detection at the expected molecular weight

• Peptide competition assay: Pre-incubate antibody with immunizing peptide to confirm specificity

• Cross-reactivity assessment: Test against related plant species if examining conservation

Similar to validation approaches used for therapeutic antibodies in clinical research, these steps help establish confidence in antibody performance . Document all validation results thoroughly, as this information will strengthen the credibility of subsequent experimental findings and may be requested during peer review of publications.
