Molecular Biology Testing Services

Exponent's biomedical, health science, and industrial hygiene experts provide rigorous quality assessments and risk analysis to evaluate the risks of microbiological and biological contamination in consumer products, medical devices, and manufacturing lines. Leveraging lateral flow immunoassays and other rapid molecular techniques, we can analyze contaminants of biological origin (human or other animal specimens, e.g., blood) and perform root-cause analyses of microbiological contaminations (bacterial, fungal, or viral).

Exponent's molecular biologists develop and validate custom protein and enzymatic assays to detect, quantify, and characterize proteins in a variety of sample types. We offer protein quantification (e.g., BCA protein assays), as well as enzyme activity assays to support product quality, contamination investigations, research needs, and disputes.

We provide a full suite of immunoassay services, including enzyme-linked immunosorbent assays (ELISAs) and western blotting, to measure specific biomolecules, impurities, or contaminants. Our team designs and optimizes assays tailored to your unique products and regulatory requirements, supporting both quality control and complex investigations.

Our laboratory offers advanced molecular diagnostic testing, including quantitative PCR (qPCR), reverse transcription PCR (RT-PCR), and nucleic acid extraction. We develop and verify custom assays for product characterization and regulatory submissions. Our scientists have supported clients in developing and validating COVID-19 PCR tests, ensuring reliable detection and quantification of viral targets.

Our scientists perform sensitive and specific allergen testing to detect trace levels of allergenic proteins in raw materials, intermediates, and finished products. We help clients ensure compliance with labeling regulations and prevent allergen-related recalls.

Exponent's consultants provide objective data analysis and science-based expert reports and testimony for disputes involving molecular biology testing and evaluation. Our rigorous approach ensures thorough, defensible findings across a range of industry challenges.

When you need expert microbiological analysis, rapid response support for contamination events, and testing services that go beyond standard protocols, rely on Exponent's unmatched expertise and state-of-the art microbiological laboratory.

Biological contamination can significantly impact product safety by introducing harmful microorganisms such as bacteria, viruses, molds, other pathogens, or other biological materials into raw materials, intermediates, or finished products. Such contamination can compromise the integrity and safety of the product, leading to potential health risks for consumers, product recalls, regulatory non-compliance, and damage to brand reputation. Effective detection and control of biological contaminants are essential to product safety, quality, and regulatory compliance.

Exponent offers clients custom immunoassay services, including ELISAs and western blots, tailored to measure specific biomolecules, impurities, or contaminants in products, ensuring both quality control and adherence to regulatory standards. Our expert teams design and optimize assays to meet unique product and industry requirements, supporting everything from quality checks to complex investigations.

Advanced molecular diagnostics, such as qPCR, RT-PCR, and nucleic acid extraction, enable precise detection and quantification of genetic material. Exponent scientists develop and validate custom assays for product characterization, supporting robust regulatory submissions. Our expertise also extends to developing and verifying tests for emerging needs, such as COVID-19 PCR diagnostics, ensuring reliable results and compliance with regulatory expectations.

Sensitive and specific allergen testing is crucial for detecting trace levels of allergenic proteins in raw materials, intermediates, and finished products. Exponent scientists help clients comply with labeling regulations, respond to allergen-related recalls, and protect consumer safety. By offering rigorous testing protocols, these services enable manufacturers to confidently manage allergen risks and uphold industry standards.
