Further Considerations of Antibody Validation and Usage: How to Avoid Reviewer Challenges
15 Jun 2016This white paper discusses some important considerations in choosing antibodies and addresses some of the key reviewer comment trends. The effective use of antibodies in research assays has always depended on multiple factors that determine the accuracy and precision of the component reagents. Research from a discussion lead by the journal Science has revealed that sensitivity, reproducibility, target specificity and application specificity are the four characteristics that define quality antibody development and validation.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Assay AssemblyAssay Assembly is technique used in drug discovery to develop assays to test the cytotoxicity, genotoxicity, or other activities of a compound on a cell. Assay assembly requires chip assembly, a delivery system and a detection and analysis method. Beneficial features of assay kits or automated systems include high-throughput, high speed and sensitivity and low signal to noise ratio.Bioprocessing / FermentationBioprocessing is the use of biological materials to perform commercial, scientific or medical research processes. Biological materials used include cells, enzymes and organisms. Usually bioprocessing requires a batch or continuous bioreactor such as a fermentor or cell culture system. The advantages of using a reactor include high productivity, easy configuration, adjustable values and automation.Data AnalysisData analysis hardware and software is available to make data processing straight-forward yet powerful. Data software can be used for math and stats, technical graphing and image analysis. In addition, software is available for specific data analysis of electrophoresis, densitometry, ELISA and DNA sequencing.ImmunoassayImmunoassays are laboratory tests that utilize antibody-antigen interactions to detect specific substances. They are widely used in diagnostics for detecting diseases, drug testing, and environmental monitoring. These assays offer rapid, sensitive, and precise detection of biomarkers, making them invaluable in clinical and research labs.
