Bioanalysis involves sample preparation techniques designed to meet rigorous standards for sensitivity, specificity, accuracy, and precision. The standards are crucial for evaluating the safety and ef...
Antimicrobial peptides (AMPs) are evolutionarily conserved peptide sequences often found in plants, animals, and humans. They play a significant role in the host’s innate immune response by acting as ...
New, novel benzodiazepines have become some of the most abused unique psychoactive substances seen today. In the United States, these compounds are not approved for prescription use. Therefore, the de...
In post-mortem cases, where drugs or pesticides have been used for their poisonous properties, traditional matrices such as urine and whole blood may be inappropriate for qualitative and quantitative ...
Pesticides, including insecticides, fungicides, and herbicides, are used extensively to increase agricultural yield. It is important to monitor organochlorine pesticides and polychlorinated biphenyls ...
Functionalized pipette tips have been available for many years. Marketed for solid phase extraction, these pipette tips carry a solid phase contained within a polymer precipitate located at the end of...
With prescription abuse rising concomitantly with licit pain management, the need to expand a wider degree of drug monitoring within a single method has been increasingly sought after. With the incide...
Solid-phase extraction is generally regarded as the gold standard when comparing sample preparation approaches. However, SPE processing can be laborious and time consuming. In most cases you are requi...
Most drugs, both licit and illicit, are excreted in urine as glucuronide conjugates. Hydrolysis using beta-glucuronidase converts the glucuronidated metabolites back to their “free” or non-conjugated ...
Traditionally the analysis of aldosterone and angiotensin (for plasma renin activity measurement) are performed separately. However, the relationship of the aldosterone-to-renin-ratio is a very useful...
