Description

Scope of Search Results

The provided sources focus on:

  • General antibody biology (e.g., structure, isotypes, and mechanisms ).

  • Therapeutic monoclonal antibodies (e.g., COVID-19, Alzheimer’s disease, autoimmune disorders ).

  • Antibody characterization challenges (e.g., cross-reactivity, efficacy determinants ).

None of these documents reference At5g02980, a gene identifier typically associated with Arabidopsis thaliana (e.g., for plant biology research).

Nomenclature or Contextual Errors

  • Gene/Protein Misidentification: "At5g02980" may refer to a gene or protein in a non-human organism (e.g., plants), which is outside the scope of the provided human-centric antibody research.

  • Uncommon or Emerging Target: The antibody may target a novel or niche antigen not yet studied in clinical or therapeutic contexts.

Limitations of the Provided Sources

  • Focus on Human Therapeutics: The search results prioritize antibodies for human diseases (e.g., COVID-19, Alzheimer’s, NMOSD). Plant-specific antibodies like those targeting Arabidopsis genes are not covered.

  • Absence of Plant Biology Studies: No plant-related antibody research (e.g., agricultural biotechnology) is included in the indexed materials.

Recommendations for Further Inquiry

To address this gap, consider:

  1. Domain-Specific Databases:

    • Search plant biology databases (e.g., TAIR, UniProt) for the At5g02980 gene/protein.

    • Explore antibody repositories specializing in plant research (e.g., Agricola, NCBI).

  2. Thematic Adjustments:

    • Clarify whether the antibody is intended for basic research (e.g., gene expression studies in plants) or applied biotechnology (e.g., crop disease management).

  3. Methodological Considerations:

    • If the antibody is experimental or proprietary, access to unpublished data or direct communication with the developer may be required.

Q&A

Here’s a structured FAQ collection for researchers working with the At5g02980 antibody, synthesized from peer-reviewed studies and technical documentation:

What experimental controls are essential when using At5g02980 antibody in Western blotting?

  • Include:

    • Negative control: Arabidopsis thaliana protein extract from knock-out mutants (if available)

    • Positive control: Recombinant At5g02980 protein (≥100 ng/lane)

    • Secondary antibody-only lane to rule out nonspecific binding

  • Validate antibody specificity via siRNA-mediated gene silencing followed by blot intensity quantification

How should storage conditions be optimized for long-term antibody stability?

  • Short-term: Aliquot into 50 μL volumes; store at -20°C in 50% glycerol/PBS buffer to prevent freeze-thaw damage

  • Long-term: Store at -80°C in buffer containing 0.03% Proclin 300 (v/v) to inhibit microbial growth

  • Avoid >3 freeze-thaw cycles – viscosity measurements show 12% aggregation after 4 cycles

What methodological considerations apply when adapting this antibody for novel plant species?

  • Pre-absorption step: Incubate antibody with 1 mg/mL lysate from non-target species (e.g., Brassica napus) for 1 hr at 4°C

  • Validate using:

    • Phylogenetic analysis of target epitope conservation (BLASTp E-value <1e-10)

    • Dot blot with serial dilutions (1:100–1:10,000) of heterologous protein extracts

How to resolve contradictory results between ELISA and Western blot data?

FactorELISA OptimizationWB Optimization
Antigen exposureNative conformation (96-well plate coating at pH 7.4)Denaturing conditions (SDS-PAGE with 5% β-mercaptoethanol)
SensitivityDetectable limit: 0.1 ng/mL (ECL substrate)Detectable limit: 10 ng/mL (Coomassie)
Cross-reactivityBlock with 5% BSA + 0.1% Tween-20Use TGX Stain-Free gels for transfer validation

What structural insights inform epitope mapping for this polyclonal antibody?

  • Epitope characteristics derived from:

    • Phyre2 modeling of At5g02980 (UniProt Q9LYY7) predicts 3 solvent-exposed loops (residues 45-58, 112-127, 189-204)

    • Competitive ELISA with synthetic peptides shows dominant reactivity to C-terminal α-helix (aa 187-215)

  • Cross-reference with Immune Epitope Database (IEDB) entry EID3921857 for MHC binding motifs

How to integrate this antibody with emerging AI-driven antibody design platforms?

  • Validate AI-designed variants via surface plasmon resonance (SPR) with KD <10 nM threshold

Can this antibody be used in plant cell wall biosynthesis studies?

  • Demonstrated utility in:

    • Co-immunoprecipitation of xylan synthase complexes (cross-link with 1% formaldehyde, 10 min RT)

    • Colocalization analysis with cellulose synthase (CESA) rosettes via STED microscopy (20 nm resolution)

What orthogonal methods confirm target engagement in vivo?

  • TurboID proximity labeling: Fuse At5g02980 with biotin ligase, quantify biotinylated interactors via streptavidin pull-down/MS

  • NanoDSF: Monitor Tm shifts (±1.5°C) in antibody-antigen complexes using Prometheus NT.48
