COX6A Antibody
Description
Overview of COX6A Antibodies
COX6A antibodies target subunits of Complex IV (cytochrome c oxidase) in the mitochondrial electron transport chain. These antibodies are essential for:
-
Detecting tissue-specific expression patterns (e.g., COX6A2 in heart/muscle vs. COX6A1 in other tissues)
-
Validating gene knockout/knockdown efficiency in experimental systems
Table 1: Disease Associations
Technical Considerations
-
Cross-Reactivity Risk: COX6A1/COX6A2 share 66% amino acid identity; rigorous validation using isoform-specific controls is critical .
-
Tissue-Specific Validation: COX6A2 antibodies require muscle/brain tissue validation, as standard cell lines often lack expression .
-
Quantitative Limitations: Semi-quantitative Western blotting remains challenging due to low COX6A2 abundance (<0.01% of mitochondrial proteome) .
Product Specs
Constituents: 50% Glycerol, 0.01M PBS, pH 7.4
Target Background
- Research has shown that the disulfide bridge in cytochrome c(6A) acts as a conformational restraint in both the folding intermediate and native state of the protein. This suggests that the disulfide bridge likely serves a structural role rather than a previously proposed catalytic role. PMID: 22085909
Q&A
Experimental Design for COX6A2 Studies
Q: How can I design an experiment to study the role of COX6A2 in mitochondrial function using CRISPR/Cas9 gene editing? A: To study COX6A2's role in mitochondrial function, you can create a COX6A2 knockout model in human induced pluripotent stem cells (hiPSCs) using CRISPR/Cas9. This involves designing guide RNAs targeting the COX6A2 gene, followed by differentiation into cardiomyocytes to assess changes in energy metabolism and oxidative stress .
Data Analysis for COX6A2 Expression
Q: How can I analyze data from COX6A2 expression studies to identify potential contradictions or inconsistencies? A: Analyzing COX6A2 expression data involves comparing mRNA levels across different conditions using techniques like qPCR. Contradictions may arise from variations in sample preparation or experimental conditions. Ensure consistent methodologies and consider using normalization controls to validate results .
Advanced Research Questions: COX6A2 and Metabolic Disorders
Q: What are the implications of COX6A2 deficiency on metabolic disorders, and how can this be studied in animal models? A: COX6A2-deficient mice have shown protection against high-fat diet-induced obesity and insulin resistance, suggesting enhanced insulin sensitivity . This can be further studied by assessing glucose tolerance and insulin sensitivity in animal models using techniques like hyperinsulinemic-euglycemic clamps.
Methodological Considerations for COX6A2 Antibody Use
Q: What are the best practices for using COX6A2 antibodies in Western blotting to ensure specificity and sensitivity? A: For optimal results with COX6A2 antibodies in Western blotting, use a polyclonal antibody at an appropriate dilution (e.g., 1/500) and ensure proper sample preparation. Avoid freeze-thaw cycles and store the antibody at -20°C to maintain its integrity .
Interpretation of COX6A2 Expression in Different Tissues
Q: How can I interpret the expression of COX6A2 in different tissues, considering potential contamination or heterogeneous expression?

Use markers specific to these tissues to validate the expression patterns and ensure accurate interpretation .
COX6A2 and Oxidative Phosphorylation
Q: What role does COX6A2 play in oxidative phosphorylation, and how can its dysfunction impact mitochondrial function? A: COX6A2 is a component of cytochrome c oxidase, crucial for oxidative phosphorylation.
