At2g04045 Antibody

What is At2g04045 and why is it significant for plant molecular biology research?

At2g04045 refers to a specific gene locus in Arabidopsis thaliana (Mouse-ear cress), a model organism widely used in plant molecular biology. The gene encodes a protein with the UniProt accession number Q4VNZ6. The significance of this target lies in its potential role in fundamental plant biological processes that researchers aim to understand through immunological detection methods. The At2g04045 antibody allows researchers to detect, quantify, and characterize this specific protein in experimental systems. This antibody is particularly valuable for researchers studying protein expression patterns, protein-protein interactions, or functional characterization of this particular gene product in Arabidopsis. The antibody enables visualization of the protein's subcellular localization, expression levels under various conditions, and potential modifications, contributing to our understanding of plant cellular and molecular mechanisms .

What are the primary applications for the At2g04045 antibody in plant research?

The At2g04045 antibody has been validated for several research applications, primarily ELISA (Enzyme-Linked Immunosorbent Assay) and Western Blot (WB). These techniques allow researchers to detect and quantify the At2g04045 protein in plant tissue samples. ELISA provides a platform for quantitative analysis, making it suitable for comparing expression levels across different experimental conditions. Western Blot enables size determination and semi-quantitative analysis, helping researchers identify post-translational modifications or degradation products. The antibody is specifically reactive to Arabidopsis thaliana proteins, making it an excellent tool for research focused on this model plant species. Importantly, this antibody is designated for research use only and should not be employed in diagnostic or therapeutic procedures, maintaining its specialized role in fundamental plant biology research .

What are the recommended storage and handling conditions for optimal At2g04045 antibody performance?

For optimal performance and longevity of the At2g04045 antibody, proper storage and handling are essential. Upon receipt, the antibody should be stored at either -20°C or -80°C. It's crucial to avoid repeated freeze-thaw cycles, as these can significantly diminish antibody activity through protein denaturation and aggregation. The antibody is supplied in liquid form containing preservatives (0.03% Proclin 300) and stabilizers (50% Glycerol, 0.01M PBS, pH 7.4) to maintain its integrity during storage. When handling the antibody for experiments, always use clean, nuclease-free pipette tips and tubes to prevent contamination. Ideally, small working aliquots should be prepared to minimize freeze-thaw cycles. When thawing the antibody, do so gradually at 4°C rather than at room temperature to preserve the protein structure and binding properties. These careful storage and handling practices will help maintain antibody specificity and sensitivity throughout your research project .

What control samples should be included when working with the At2g04045 antibody?

When working with the At2g04045 antibody, incorporating appropriate controls is essential for experimental validity and interpretation. Researchers should include the following controls:

• Positive control: Lysate or extract from wild-type Arabidopsis thaliana tissues known to express the At2g04045 protein.

• Negative control: Samples from At2g04045 knockout/knockdown plants if available, or tissues known not to express the target.

• Loading control: Detection of a housekeeping protein (like actin or tubulin) to normalize expression levels.

• Isotype control: An irrelevant isotype-matched antibody (rabbit IgG in this case) to assess non-specific binding.

• Secondary antibody control: Samples treated with only secondary antibody to detect non-specific binding.

These controls help verify antibody specificity, validate results, and provide normalization for quantitative analyses. Direct binding assays should always include both positive and negative antibody and antigen controls. At least one isotype-matched, irrelevant control antibody should be tested alongside the At2g04045 antibody to distinguish specific from non-specific binding .

How can researchers validate the specificity of the At2g04045 antibody in their experimental system?

Validating antibody specificity is critical for ensuring reliable research outcomes. For the At2g04045 antibody, researchers should implement a multi-step validation strategy:

• Genetic validation: Compare antibody reactivity between wild-type Arabidopsis and genetic knockouts/knockdowns of At2g04045. Absence or reduced signal in the knockout/knockdown samples strongly supports antibody specificity.

• Peptide competition assay: Pre-incubate the antibody with excess purified At2g04045 protein or immunizing peptide before application to samples. Significant signal reduction indicates specific binding.

• Orthogonal method comparison: Correlate protein detection results with mRNA expression data from RT-PCR or RNA-seq.

• Cross-reactivity assessment: Test the antibody against related proteins or in plants expressing tagged versions of At2g04045.

• Immunoprecipitation followed by mass spectrometry: This approach can identify all proteins captured by the antibody, confirming whether At2g04045 is the primary target.

The specificity assays should include direct binding tests with appropriate positive and negative controls. When possible, the protein bearing the reactive epitope should be biochemically defined, and the antigenic epitope itself determined. Fine specificity studies using antigenic preparations of defined structure should be conducted to characterize antibody specificity through inhibition or other techniques .

What approaches should be used to optimize At2g04045 antibody concentration for Western blot applications?

Optimizing the At2g04045 antibody concentration for Western blot requires a systematic approach to balance specific signal detection with minimal background:

• Titration experiment: Perform a dilution series (typically 1:500, 1:1000, 1:2000, 1:5000, 1:10000) of the antibody against a constant amount of positive control sample. The At2g04045 antibody is typically used at 1:1000 dilution as a starting point.

• Time-course optimization: Test different incubation periods (1 hour at room temperature versus overnight at 4°C) to determine optimal binding conditions.

• Blocking optimization: Compare different blocking reagents (BSA, non-fat milk, commercial blockers) at various concentrations (3-5%) to minimize background while preserving specific signal.

• Buffer optimization: Test different buffer compositions and detergent concentrations that might affect antibody-antigen interactions.

• Signal detection analysis: Generate a signal-to-noise ratio for each condition by quantifying band intensity relative to background.

Document these optimization steps in a standardized table format:

This systematic approach ensures reliable and reproducible Western blot results while conserving valuable antibody resources .
