Target Identification evaluates the target feasibility of whether it is possible to detect with the available technology and resources. Types of targets include proteins, antibodies, or nucleic acids. Common examples include pathogen-produced protein epitopes, cytokines, enzymes, known associated up or down-regulated proteins, or antibody response.
Assay Design & Optimization
Selecting the assay design is dependent on whether detection will be via molecular methods, antigen capture, or antibody detection. Common assay formats include ELISA, lateral flow, PCR/qPCR and cell or tissue-based assays. Assay development considerations include relevant controls, conditions, and the reagents necessary to perform the test. Once design is complete, conditions are optimized to ensure the assay is sensitive, specific, and reproducible.
Assay Production & Quality Control
The validation of a diagnostic assay adheres to the processes outlined by local regulations. In the United States, the 510(k) trial, established by the FDA, involves collecting sample data for analysis. The analysis evaluates the precision, accuracy, reportable range, reference range, analytic sensitivity, and analytic specificity of the assay.
To maintain accuracy and reliability over time, quality control procedures are implemented. These procedures may include continuous monitoring of assay performance, regular staff training, and other measures.
GenScript can offer ISO 9001:2015, ISO 13485, or GMP-grade depending on customer quality requirements.
