Toxicology ELISA Kits and Multiplex Immunoassays |
Toxicity is crucial in biological research and plays an important role in drug development. Toxicity studies aim to remove toxic compounds early in the drug development process, as drug-induced toxicities are the leading cause of drug failures.
Thermo Fisher Scientific offers sensitive and accurate assays to probe and understand the effects of cytotoxins in biological systems. A variety of soluble biomarkers are available in different formats to suit your research needs.
Overview of toxicology research and testing
Toxicology encompasses scientific disciplines such as biology, chemistry, pharmacology, and medicine. Covering the entire biological system from cells to ecosystems, toxicology is the study of adverse effects of compounds on living organisms. The effects of toxins are influenced through their ADME (absorption, distribution, metabolism, and excretion) properties, along with their interactions with other molecules or cellular components [1].
Toxic substances interact in vivo in four steps. First, toxins must reach the blood stream. They can be absorbed through the gastrointestinal tract, skin exposure, or via lung inhalation. Once absorbed, toxic substances then enter the circulatory system through lymph and/or blood and get distributed to various organs and tissues.
Circulating toxins undergo metabolism or biotransformation, where the compounds get chemically transformed into metabolites that may elicit a weaker or stronger toxicological effect in vivo. Finally, toxins and/or their metabolites are excreted from the body. If a toxin can be rapidly eliminated from the body, it will have less chance of accumulating at the target site and inflicting damage. The most common methods of excretion are through the renal system or the digestive tract [2].
General testing methods
Toxicology testing can be broadly grouped into different categories. In research settings, synthetic and natural products/compounds are tested to assess their potential toxicological effects. In development and manufacturing of regulated materials for sale, like medicines, pesticides, cosmetics, additives, etc., all compounds must undergo toxicity testing on their final products prior to public use.
Testing methods will uncover species, organ, and dose-specific effects of compounds in question. The most common methods for testing are studying accidental exposure, in vitro studies using cell lines, and in vivo studies involving animal models [3]. At the end of testing, the LD50 of the compound is determined, which gives a value known to be a lethal dosage in 50% of the tested population.
ELISA and bead-based testing
As part of testing, it is important to understand the mechanism of action of compounds and their potential cytotoxic effects that are elicited in the body. Immunotoxicity can be measured in vitro using applications such as ELISA or ProcartaPlex multiplex immunoassays. These assays can be used to test a variety of biomarkers in the body to determine how toxins affect biomarkers. To that extent, Table 1 highlights a few examples of published data on toxicology research and testing using these methods.
A benefit of bead-based assays is the ability to multiplex—allowing simultaneous testing of different biomarkers at one time. A cost-effective and time-saving application, it requires only a small volume of sample (which is advantageous in the case of restricted/limited samples). Researchers can gain a comprehensive understanding of different toxicological effects due to the vast number of biomarkers across different species.

Toxicology research ProcartaPlex Multiplex Immunoassays
Invitrogen ProcartaPlex panels allow concurrent detection and measurement of soluble biomarkers implicated with toxin administration. Select from our preconfigured panels that are specifically designed and optimized for hepatotoxicity and nephrotoxicity research (Table 4) or use the panel configurator to customize a panel suited to your research needs associated with toxicology research and testing.
ProcartaPlex assays for liver and kidney toxicity enable the simultaneous quantification of up to 11 toxicity targets (including FDA-recommended biomarkers) in a single well [4]. Among others, highly relevant CYP targets for ADME/Tox studies are part of the ProcartaPlex menu. These assays can be used, along with other assay types such as enzyme activity assays or QuantiGene Plex mRNA to obtain a more holistic picture of your drug candidate (Figure 3). Organ-specific toxicity tests, specifically for the kidney are of high interest because it is a central detoxification organ that is exposed to drugs, reactive metabolites, and environmental chemicals. Kidney toxicity is routinely assessed during preclinical safety evaluations. Nephrotoxicity assays are tested against the most common sample types such as urine, serum/plasma and cell culture supernatant.

Multiplex gene expression and protein assays
QuantiGene RNA gene expression assays provide a fast and high-throughput solution for multiplexed gene expression quantitation, with simultaneous measurement of up to 80 genes of interest in a single well of a 96- or 384-well plate. The QuantiGene Plex assay is based on hybridization and incorporates branched DNA (bDNA) technology, which uses signal amplification rather than target amplification for direct measurement of RNA transcripts. The assay is run on the Luminex® platform, has a simple workflow and does not require RNA purification. These features allow the user to merge the QuantiGene workflow for gene expression profiling with the ProcartaPlex workflow for protein quantitation (Figure 6) using the same sample. To study the gene expression of relevant ADME (absorption, distribution, metabolism, and excretion) and toxicological biomarkers, the QuantiGene Plex Human ADMETOX Panel, 80-plex is available to analyze 80 genetic targets implicated in drug metabolism, including enzymes, transporters, and CYPs.
