WDL2 Antibody

Basic Research Questions

• What is WDL2 Antibody and what are its primary research applications?

  WDL2 Antibody (CSB-PA598187XA01DOA, Q9ASW8) is a polyclonal antibody developed for detection of the WDL2 protein in research applications. Based on standard antibody applications, WDL2 antibody can be utilized in multiple experimental techniques including Western blotting, immunohistochemistry (IHC), immunocytochemistry (ICC), and enzyme-linked immunosorbent assays (ELISA) .

  Methodologically, researchers should validate the antibody in their specific experimental system before proceeding with larger studies. This typically involves positive and negative controls to confirm specificity, as well as determining optimal dilutions for each application (typically starting with manufacturer recommendations and optimizing as needed).

• How should researchers properly store and handle WDL2 Antibody to maintain its efficacy?

  Based on standard antibody handling protocols, WDL2 Antibody should be stored according to these guidelines:

  Storage Condition	Duration	Temperature
  As supplied	12 months	-20 to -70°C
  After reconstitution (sterile conditions)	1 month	2 to 8°C
  After reconstitution (sterile conditions)	6 months	-20 to -70°C

  Researchers should use manual defrost freezers and avoid repeated freeze-thaw cycles as these can significantly degrade antibody performance . For daily handling, minimize the time the antibody spends at room temperature, use sterile technique when aliquoting, and consider preparing single-use aliquots to avoid repeated freeze-thaw cycles.

• What experimental controls should be included when using WDL2 Antibody in Western blot analysis?

  For rigorous Western blot analysis with WDL2 Antibody, the following controls are essential:

  • Positive control: Sample known to express the target protein

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

  • Loading control: Detection of housekeeping proteins (e.g., GAPDH, β-actin) to normalize expression levels

  • Molecular weight marker: To confirm the detected band is of expected molecular weight

  • Secondary antibody-only control: To identify non-specific binding of the secondary antibody

  Additionally, researchers should consider including a blocking peptide control if available to confirm antibody specificity . When interpreting Western blot results, researchers should examine both the presence and absence of bands at the expected molecular weight and evaluate the signal-to-noise ratio.

• What dilution ranges should be tested when optimizing WDL2 Antibody for immunofluorescence studies?

  When optimizing WDL2 Antibody for immunofluorescence:

  1. Start with the manufacturer's recommended dilution range

  2. Test a dilution series (typically 1:50 to 1:1000 for polyclonal antibodies)

  3. Include appropriate positive and negative controls

  4. Evaluate signal-to-noise ratio at each dilution

  For cell fixation, compare performance between different methods:

  Fixation Method	Advantages	Considerations
  Paraformaldehyde (4%)	Preserves cell morphology	May reduce epitope accessibility
  Methanol/Acetone	Better for some intracellular epitopes	Can disrupt membrane structures
  Combined Approaches	Compromises between methods	Protocol optimization required

  When evaluating results, examine specificity of staining pattern, intensity, and background levels .

Advanced Research Questions

• How can researchers validate WDL2 Antibody specificity for critical experiments and publications?

  Advanced validation of WDL2 Antibody specificity should include multiple complementary approaches:

  1. Genetic approaches:

     • siRNA/shRNA knockdown of target protein

  When interpreting data from these validation experiments, researchers should quantitatively analyze the reduction in signal following knockdown/knockout treatments (expecting at least 70-80% reduction) and document all validation efforts in publications .

• What strategies can resolve discrepancies in experimental results when using WDL2 Antibody across different applications?

  When faced with discrepancies between applications (e.g., positive Western blot but negative immunohistochemistry results):

  1. Epitope availability analysis:

     • Protein conformation differences between applications

     • Epitope masking by protein-protein interactions

     • Effects of fixation on epitope structure

  Coefficient	Interpretation	Limitations
  Pearson's r > 0.5	Moderate co-localization	Sensitive to background
  Manders' > 0.7	Strong co-localization	Less sensitive to intensity differences
