Skb15 Antibody targets PAK1 Interacting Protein 1 (PAK1IP1), a protein involved in cellular signaling pathways. The term "skb15" appears to be an alternative name for PAK1IP1, with the antibody specifically recognizing epitopes within this target protein . PAK1IP1 has an observed molecular weight of approximately 43 kDa and plays roles in various cellular processes that researchers investigate through antibody-based detection methods .
Optimal storage for skb15/PAK1IP1 Antibody is at -20°C in lyophilized form. Reconstitution should be performed using 100 μl of sterile distilled water with 50% glycerol to reach a concentration of 1 mg/ml . After reconstitution, avoid repeated freeze/thaw cycles to maintain antibody integrity and binding efficiency. For long-term storage planning in research projects, it's advisable to aliquot the reconstituted antibody to minimize degradation from repeated temperature fluctuations .
Skb15/PAK1IP1 Antibody has been validated for several research applications including:
| Application | Recommended Dilution | Notes |
|---|---|---|
| Western Blotting (WB) | 1:500 - 1:2000 | For protein detection and quantification |
| Immunohistochemistry (IHC) | 1:100 - 1:200 | For tissue localization studies |
| ELISA | 1:20000 - 1:80000 | For quantitative detection |
Researchers should note that optimal dilutions may vary based on specific experimental conditions, and optimization is recommended for each new experimental setup .
Validating antibody specificity is crucial for reliable research outcomes. For skb15 Antibody, specificity validation should include:
Positive and negative control samples with known expression patterns of PAK1IP1
Western blot analysis to confirm the correct molecular weight (43 kDa for PAK1IP1)
Peptide competition assays to demonstrate specific binding
Testing cross-reactivity with similar proteins in your experimental system
Drawing from antibody research principles, recent advances in antibody validation recommend a multiplex approach similar to the competition binding assay described for other antibodies, where antibody equivalency with well-characterized monoclonal antibodies can be assessed .
Proper experimental controls are essential when using skb15 Antibody:
| Control Type | Purpose | Implementation |
|---|---|---|
| Positive Control | Confirms antibody functionality | Samples known to express PAK1IP1/skb15 |
| Negative Control | Assesses non-specific binding | Samples lacking PAK1IP1/skb15 expression |
| Isotype Control | Evaluates background from antibody class | Matched IgG from same host species (rabbit) |
| Secondary-only Control | Identifies secondary antibody artifacts | Omit primary (skb15) antibody |
| Blocking Peptide Control | Confirms epitope specificity | Pre-incubate antibody with immunogen (AA 55-297 of human PAK1IP1) |
These controls help distinguish between true signal and experimental artifacts, particularly important in complex applications like IHC where tissue autofluorescence or endogenous enzyme activity can confound results .
Optimization strategies for skb15 Antibody vary by application:
For Western Blotting:
Test multiple antibody concentrations within the 1:500-1:2000 range
Optimize blocking solutions to reduce background (typically 3-5% BSA or non-fat milk)
Adjust incubation times and temperatures (4°C overnight vs. room temperature for 1-2 hours)
Consider enhanced chemiluminescence detection systems for improved sensitivity
For Immunohistochemistry:
Compare different antigen retrieval methods (heat-induced vs. enzymatic)
Test a range of antibody concentrations starting with 1:100-1:200
Optimize incubation conditions and washing protocols
Evaluate different detection systems based on required sensitivity
Recent advances in antibody technology, as seen in the development of novel antibody assays, suggest that assessing binding parameters across multiple experimental conditions can significantly improve reproducibility and sensitivity .
Since the skb15/PAK1IP1 Antibody targets a specific recombinant fragment (amino acids 55-297 of human PAK1IP1) , epitope accessibility may be affected by:
Protein conformation in different sample preparation methods
Fixation-induced epitope masking
Protein-protein interactions obscuring the target epitope
Post-translational modifications affecting antibody recognition
Researchers should consider:
Testing multiple sample preparation protocols
Evaluating different fixation methods for IHC/ICC

Target protein expression levels: PAK1IP1/skb15 may be expressed at varying levels in different tissues or cell lines
Antibody lot variation: Polyclonal antibodies like skb15 Antibody may show batch-to-batch variations
Cross-reactivity: The antibody may recognize similar epitopes in related proteins
To address these issues:
Standardize sample preparation protocols across experiments
Include positive controls with known PAK1IP1 expression levels
Document antibody lot numbers and maintain consistent sourcing
Validate results using alternative detection methods (e.g., mass spectrometry)
Research on antibody specificity indicates that even minor variations in experimental conditions can significantly impact binding profiles, particularly for polyclonal antibodies .
For quantitative analysis using skb15 Antibody:

| ELISA | Standard curve with recombinant PAK1IP1 protein | Ensure parallelism between standards and samples |
When analyzing data from antibody-based experiments, researchers should consider the specific binding characteristics of skb15 Antibody. Modern approaches to antibody analysis, as seen in recent studies, emphasize the importance of quantitative frameworks that account for both binding affinity and specificity .
The polyclonal nature of skb15 Antibody has important implications:
Multiple epitope recognition: Polyclonal antibodies recognize multiple epitopes within the target region (amino acids 55-297 of PAK1IP1), potentially increasing sensitivity but also raising specificity concerns
Batch variation: Different production lots may contain varying antibody populations with different epitope affinities
Cross-reactivity potential: Higher risk of recognizing similar epitopes in related proteins
Researchers should:
Validate each new lot against reference standards
Consider epitope mapping to characterize the specific binding profile
Design experiments with appropriate controls to account for potential cross-reactivity
Recent advances in antibody research have highlighted how polyclonal antibodies can be advantageous in certain applications while requiring more rigorous validation protocols compared to monoclonal alternatives .
