HepG2 | ~45 | ++ |
SK-OV-3 | ~45 | + |
Cell Line | % Positive Staining (vs. Isotype Control) |
---|---|
A549 | 89.7% |
PC-3 | 76.4% |
Knockdown Validation: Used to confirm LPAR6 silencing in keratinocyte models
Receptor Localization: Membrane staining in hair follicle stem cells
Condition | Observed Alterations | Reference |
---|---|---|
Hypotrichosis | Loss-of-function mutations in LPAR6 | |

Rat | Limited | Weak signal in brain lysates |
Non-Specific Binding: Pre-absorption with blocking peptide (e.g., BLP-LR036 ) required for specificity
Fixation Sensitivity: Methanol fixation reduces epitope accessibility by 40-60%
Given the lack of specific information on "APRR6 Antibody" in the search results, I will create a general FAQ for researchers on antibodies, focusing on aspects relevant to academic research scenarios. This will include experimental design, data analysis, and methodological considerations.
To validate the specificity of an antibody, you should:
Use multiple controls: Include negative controls (e.g., cells or tissues lacking the target antigen) and positive controls (e.g., cells or tissues known to express the target antigen).
Perform Western blot and immunohistochemistry: These techniques help confirm the antibody's ability to bind specifically to the target protein in different contexts.
Assess cross-reactivity: Test the antibody against closely related proteins or peptides to ensure it does not bind non-specifically.
Quantification: Use software to quantify Western blot bands or immunohistochemical staining intensities.
Statistical analysis: Apply appropriate statistical tests to compare results between groups.
Consider biological variability: Account for variability in biological samples by using multiple replicates and controls.
Cross-reactivity can lead to false positives or misinterpretation of results. To mitigate this:
Use multiple antibodies: Validate findings with different antibodies targeting the same antigen.
Assess specificity: Test antibodies against a panel of related and unrelated antigens.
Phage display: Utilize phage display techniques to select antibodies with desired specificity profiles.
Computational modeling: Employ biophysics-informed models to predict and design antibodies with customized binding properties .
Specificity and sensitivity: Choose antibodies with high specificity and sensitivity for the target antigen.
Validation: Ensure the antibody has been validated in relevant experimental systems.
Epitope recognition: Consider the epitope recognized by the antibody to avoid interference with other reagents or proteins.
Non-specific binding: Use blocking agents or optimize antibody concentrations to reduce background.
Lack of signal: Check antibody storage conditions, optimize fixation protocols, or use signal amplification techniques.
Personalized medicine: Antibodies are being developed for targeted therapies based on individual patient profiles.
Synthetic biology: Advances in antibody engineering allow for the creation of novel binding proteins with tailored properties.
Open communication: Share protocols and results openly to facilitate reproducibility.
Collaborative validation studies: Participate in multi-lab validation efforts to establish reliable antibody standards.
Animal welfare: Consider the source of antibodies and opt for humanized or recombinant alternatives when possible.
Data integrity: Ensure transparency in reporting methods and results to maintain research integrity.
High-throughput sequencing: Enables detailed analysis of antibody libraries and selection processes.
Computational tools: Facilitate the design and prediction of antibody specificity and affinity .
