subject: Custom Antibody Array Development Services – FAQ [print this page]
Q1: What is an antibody array? An antibody array is a high-throughput platform that uses immobilized antibodies to simultaneously detect multiple proteins or biomarkers in a single sample.
Q2: What are the advantages of custom antibody arrays? Custom antibody arrays enable multiplex detection, reduced sample consumption, high sensitivity, and the ability to profile complex signaling pathways or disease biomarkers in parallel.
Q3: What types of antibody arrays can be developed? Common formats include sandwich arrays, direct-label arrays, and reverse-phase protein arrays (RPPA), depending on the application and sample type.
Q4: What samples can be analyzed using antibody arrays? They can be applied to serum, plasma, cell lysates, tissue extracts, and other biological samples for proteomic analysis.
Q5: What are typical applications of antibody array technology? Applications include biomarker discovery, cytokine profiling, pathway analysis, disease mechanism studies, and drug response evaluation.
Q6: How is specificity ensured in antibody arrays? Specificity is achieved through rigorous antibody validation, optimized immobilization strategies, and careful control of cross-reactivity during assay development.
Q7: Can antibody arrays be customized for specific research targets? Yes, arrays can be tailored to include selected targets, pathways, or disease-specific biomarkers based on project requirements.
Q8: How are antibody array results analyzed? Data analysis typically involves signal normalization, background correction, and quantitative comparison across samples to identify differential protein expression.
