Q&A

What is NSFBx and what biological systems can it be studied in?

NSFBx is a protein found in Arabidopsis thaliana (Mouse-ear cress), a model organism widely used in plant molecular biology research. The NSFBx Antibody (CSB-PA682716XA01DOA) has been specifically developed to recognize and bind to this target protein. The antibody shows species reactivity with Arabidopsis thaliana and is designed for research applications in plant molecular biology . When designing experiments, researchers should note that this antibody has not been validated for cross-reactivity with other plant species, making it most suitable for studies specifically focused on A. thaliana systems or closely related species where sequence homology might permit cross-reactivity.

What are the recommended storage conditions for NSFBx Antibody?

For optimal antibody performance and longevity, store NSFBx Antibody (CSB-PA682716XA01DOA) at -20°C or -80°C immediately upon receipt. Repeated freeze-thaw cycles significantly compromise antibody functionality and should be strictly avoided. The antibody is supplied in a storage buffer containing 0.03% Proclin 300 (as a preservative), 50% Glycerol, and 0.01M PBS at pH 7.4 . To minimize freeze-thaw cycles, it is recommended to aliquot the antibody upon initial thawing into volumes appropriate for single experiments. Each aliquot should be clearly labeled with the antibody name, catalog number, and date of aliquoting. For short-term use (within 1-2 weeks), storing aliquots at 4°C is acceptable, but long-term storage requires -20°C or -80°C temperatures.

What detection methods are validated for NSFBx Antibody?

Based on technical specifications, NSFBx Antibody has been validated for Enzyme-Linked Immunosorbent Assay (ELISA) and Western Blotting (WB) applications . When using this antibody for Western Blotting, researchers should optimize protocols considering the following parameters:

ParameterRecommended ConditionsNotes
Dilution range1:500 to 1:2000Optimization required for specific applications
Blocking solution5% non-fat milk in TBSTBSA may be substituted if background is high
Secondary antibodyAnti-rabbit IgGTypically HRP or fluorophore-conjugated
Positive controlArabidopsis thaliana leaf extractEnsures antibody functionality
Expected band sizeBased on UniProt Q5EAF6Confirm with molecular weight standards

For ELISA applications, researchers should start with a 1:1000 dilution and adjust based on signal strength. Validation experiments using known positive and negative controls are essential before proceeding with experimental samples to ensure antibody specificity and sensitivity .

How can epitope specificity be verified when troubleshooting NSFBx Antibody detection issues?

When encountering detection problems with NSFBx Antibody, a systematic verification of epitope specificity is crucial. This polyclonal antibody was raised against recombinant Arabidopsis thaliana NSFBx protein and purified using antigen affinity methods . Consequently, its epitope recognition may be influenced by protein folding, post-translational modifications, or protein-protein interactions in experimental samples.

To verify epitope accessibility and specificity:

  • Perform parallel analyses using denaturing and non-denaturing conditions to determine if epitope recognition is conformation-dependent

  • Pre-absorb the antibody with purified antigen (if available) to confirm specificity through signal reduction

  • Compare detection patterns between wild-type and NSFBx-knockout mutants (if available)

  • Consider using alternative fixation methods if performing immunohistochemistry, as some fixatives may mask the epitope

  • Test the antibody on recombinant NSFBx protein as a positive control

Researchers should also consult the UniProt entry Q5EAF6 to identify potential regions of post-translational modifications that might interfere with antibody binding. For particularly challenging detection scenarios, epitope mapping using peptide arrays can identify the specific binding regions of this polyclonal antibody.

What are the optimal normalization controls for quantitative analysis using NSFBx Antibody?

For rigorous quantitative analysis using NSFBx Antibody in Arabidopsis thaliana research, appropriate normalization controls are essential to ensure reliable interpretations of protein expression levels. The following normalization approach is recommended:

  • Internal loading controls: Use antibodies against housekeeping proteins with stable expression across experimental conditions, such as:

    • Actin (plant actin-specific antibodies)

    • GAPDH (glyceraldehyde-3-phosphate dehydrogenase)

    • Tubulin (α or β isoforms)

  • Sample preparation controls:

    • Include a dilution series of a reference sample to ensure signal linearity

    • Process all experimental samples simultaneously to minimize technical variation

  • Quantification methodology:

    • Use digital image analysis software that can correct for background signals

    • Apply consistent region-of-interest parameters across all blots/plates

    • Report data as normalized ratios rather than absolute intensity values

For experiments examining NSFBx expression under varying conditions (e.g., stress responses, developmental stages), researchers should validate that the chosen housekeeping proteins maintain stable expression under those specific conditions. When publishing results, include detailed information about normalization methods and raw data visualization to enable proper peer evaluation of quantitative claims.

How can NSFBx Antibody be integrated into co-immunoprecipitation workflows to study protein interactions?

NSFBx Antibody (CSB-PA682716XA01DOA) can be effectively utilized in co-immunoprecipitation (Co-IP) experiments to identify protein interaction partners in Arabidopsis thaliana. As this is a polyclonal antibody raised in rabbit , it offers good versatility for pulling down protein complexes. When designing Co-IP protocols with this antibody, consider the following methodological approach:

  • Preparation phase:

    • Cross-link the NSFBx Antibody to Protein A/G beads to prevent antibody co-elution with the target protein

    • Prepare fresh plant tissue lysates using gentle lysis buffers (e.g., 50 mM Tris-HCl pH 7.5, 150 mM NaCl, 1% Triton X-100, 0.5% NP-40, with protease inhibitors)

    • Pre-clear lysates with naked beads to reduce non-specific binding

  • Immunoprecipitation:

    • Incubate pre-cleared lysates with antibody-coupled beads overnight at 4°C with gentle rotation

    • Wash stringently (at least 5 times) with decreasing salt concentrations to maintain specific interactions

    • Elute protein complexes using either low pH buffer or SDS loading buffer depending on downstream applications

  • Control experiments:

    • Include a non-specific IgG from the same species (rabbit) as a negative control

    • Where possible, include lysates from NSFBx-knockout plants as specificity controls

    • Perform reverse Co-IP with antibodies against suspected interaction partners to confirm bidirectional interaction

  • Analysis of results:

    • Submit eluted samples for mass spectrometry analysis to identify novel interaction partners

    • Confirm key interactions using orthogonal methods such as yeast two-hybrid or bimolecular fluorescence complementation

This methodological framework provides a robust approach for investigating NSFBx protein complexes in plant systems, with particular attention to minimizing false positives through appropriate controls.

What strategies can resolve non-specific binding issues with NSFBx Antibody in Western blots?

    • Extend blocking time to 2 hours at room temperature or overnight at 4°C

    • Add 0.1-0.3% Tween-20 to blocking buffer to reduce hydrophobic interactions

  • Antibody dilution optimization:

    • Test serial dilutions (e.g., 1:500, 1:1000, 1:2000, 1:5000) to identify optimal signal-to-noise ratio

    • Prepare antibody solutions in fresh blocking buffer

    • Consider adding 0.05% sodium azide to antibody solution for multi-day incubations

  • Washing stringency:

    • Increase number of washes (minimum 4-5 washes of 10 minutes each)

    • Use higher concentration of Tween-20 (0.1-0.2%) in wash buffer

    • Include one high-salt wash (500 mM NaCl) to disrupt low-affinity interactions

  • Sample preparation refinement:

    • Ensure complete protein denaturation with adequate SDS and heating

    • Include reducing agents (DTT or β-mercaptoethanol) to disrupt disulfide bonds

    • Consider using gradient gels to improve protein separation

  • Advanced techniques for persistent issues:

    • Pre-absorb antibody with Arabidopsis extract from NSFBx knockout plants
