ADL393W Antibody

What is ADL393W Antibody and what are its primary applications in research?

ADL393W Antibody (CSB-PA744980XA01DOT-2) is a rabbit-derived polyclonal antibody that specifically targets the Ashbya gossypii (strain ATCC 10895 / CBS 109.51 / FGSC 9923 / NRRL Y-1056) ADL393W protein. This unconjugated antibody has been validated for ELISA and Western Blot applications in fungal research . The antibody is purified using Antigen Affinity techniques and corresponds to UniProt Number Q755R3 and Entrez Gene ID 4619836, making it a valuable tool for researchers investigating fungal protein expression and characterization .

What components are included in the ADL393W Antibody package and how should they be utilized in experimental design?

The ADL393W Antibody package includes three essential components:

• 200μg of antigens (used as positive control)

• 1ml of pre-immune serum (used as negative control)

• Rabbit polyclonal antibodies purified by Antigen Affinity

These components provide a complete validation system for researchers. The positive control antigen allows for standardization of assays and confirmation of antibody activity, while the pre-immune serum serves as a negative control to identify any non-specific binding. This comprehensive package enables researchers to implement robust experimental designs with appropriate controls for reliable data interpretation.

What is the optimal storage and handling protocol for maintaining ADL393W Antibody activity?

For optimal preservation of antibody reactivity and specificity, ADL393W Antibody should be stored at either -20°C or -80°C according to the manufacturer's specifications . While -20°C is sufficient for short-term storage, -80°C is recommended for long-term preservation. To prevent activity loss from repeated freeze-thaw cycles, researchers should aliquot the antibody upon receipt. When handling the antibody, maintain cold chain practices by keeping it on ice during experimental procedures and using appropriate buffer systems that maintain protein stability.

What is the recommended protocol for using ADL393W Antibody in Western Blot applications?

For Western Blot applications with ADL393W Antibody, researchers should follow this optimized protocol:

• Sample preparation: Extract proteins from fungal samples using appropriate lysis buffers containing protease inhibitors.

• SDS-PAGE: Separate 10-50μg of protein per lane on an SDS-polyacrylamide gel.

• Transfer: Transfer proteins to a PVDF or nitrocellulose membrane.

• Blocking: Block the membrane with 5% non-fat milk or 3-5% BSA in TBST for 1 hour at room temperature.

• Primary antibody incubation: Dilute ADL393W Antibody (starting dilution 1:1000, optimize as needed) and incubate overnight at 4°C.

• Washing: Wash 3-5 times with TBST buffer.

• Secondary antibody incubation: Use HRP-conjugated anti-rabbit IgG (typically 1:5000-1:10000) for 1 hour.

• Detection: Apply chemiluminescent substrate and image appropriately.

This protocol is aligned with standard immunoblotting techniques as demonstrated in similar antibody-based studies .

  • Determine optimal coating time (overnight at 4°C vs. 2 hours at room temperature)

• Antibody titration:

  • Perform checkerboard titration with serial dilutions of ADL393W Antibody

  • Start with manufacturer's recommended dilution (1:1000) and test 2-fold dilutions

  • Plot signal-to-noise ratio to identify optimal concentration

• Detection system optimization:

  • Compare different secondary antibody concentrations

Similar optimization approaches have proven effective in antibody-based ELISA systems for detecting antibodies against therapeutic proteins, as demonstrated in research on anti-Adalimumab antibody assays .

What controls are essential when designing experiments with ADL393W Antibody?

Proper experimental design with ADL393W Antibody requires these essential controls:

• Antibody-specific controls:

  • Pre-immune serum (provided) - establishes baseline reactivity

  • Primary antibody omission - identifies secondary antibody background

  • Antigen competition - confirms binding specificity using the provided antigen

• Sample-specific controls:

  • Positive control: Ashbya gossypii extract or recombinant ADL393W protein

  • Negative control: Samples known not to express the target protein

  • Loading control: Detection of housekeeping proteins for normalization

• Technical controls:

  • Concentration gradient to demonstrate signal linearity

  • Multiple biological replicates to ensure reproducibility

The importance of proper controls is emphasized in research on antibody validation, where controls are critical for distinguishing specific from non-specific binding .

How does the polyclonal nature of ADL393W Antibody affect experimental design and data interpretation?

The polyclonal nature of ADL393W Antibody has several important implications for research:

• Multi-epitope recognition:

  • Recognizes multiple epitopes on the target protein

  • Less susceptible to epitope masking due to protein modifications

  • Potentially higher sensitivity than monoclonal alternatives

• Experimental considerations:

  • Batch-to-batch variation may occur, requiring lot-specific validation

  • Cross-reactivity potential requires thorough specificity testing

  • Signal intensity may differ from monoclonal antibodies

• Data interpretation:

  • Stronger signal may result from binding to multiple epitopes rather than higher protein abundance

  • Comparison between samples requires consistent antibody lots

  • Quantitative analyses should include standard curves

These considerations align with known characteristics of polyclonal antibodies as discussed in antibody research literature .

What approaches can be used to validate ADL393W Antibody specificity in experimental systems?
