Immunochemistry Instruments and Reagents

Technologies flipping traditional immunoassays

New assays are quicker, more sensitive, can be conducted high-throughput, and require minimal sample.

The diagnostics market is constantly evolving and companies that want to stay ahead of the curve need to be continually exploring new approaches and innovations to ensure the future of their product. Even a relatively traditional, well-established market like immunoassay is not immune to the quickening pace of change and developers in these areas need to be live to innovation to continue to attract consumers and stay relevant.

During the past two decades, a wide range of immunoassay analyzers has been developed to provide the quantitative, semi-quantitative, or qualitative detection of analytes. Tremendous advances in immunoassay formats, bioanalytical platforms, immunoanalytical systems, and complementary technologies have led to various emerging immunochemistry technologies. Initially, most of the analyzers, developed several decades ago, were based on radioimmunoassay (RIA) and enzyme-linked immunosorbent assay (ELISA). Owing to extremely high sensitivity, specificity, precision, and throughput of ELISA, this format has served as the gold standard for a plethora of analytes and the last two decades have seen tremendous innovation in ELISA technology. Automated assays are equipped with robotic workstations while the microtiter plate (MTP) readers have also improved drastically in terms of technology, features, and cost-effectiveness. Advanced bioengineering, microfluidic, and biosensor technologies have further led to the development of prominent immunoanalytical systems including surface plasmon resonance (SPR)-based instruments for label-free immunoassays. These systems have become the global standard for developing rapid analyzers for the detection of analytes and screening of immunological components based on the determination of biomolecular interactions.

Technology trends
New technologies are flipping traditional antibody-based assays on their heads. These assays are quicker, more sensitive, can be conducted high-throughput, and require minimal sample.

Mass cytometry (CyTOF). Instead of the traditional fluorescent probes used in flow cytometry, mass cytometry employs heavy-metal-labeled probes to significantly reduce signal overlap and increase the number of detectable parameters to over 100. The Helios mass cytometer by Fluidigm is currently the only platform on which mass cytometry can be performed and get the most detailed information from every sample.

ELISA. Enzyme-linked immunosorbent assay (ELISA) is a plate-based assay that uses antibodies to detect and quantify their ligands (often proteins) within a liquid sample. Traditional ELISAs can only detect a single analyte and have limited sensitivity, which makes the detection of low-abundance analytes difficult. The two new ELISA platforms are addressing these shortcomings.

Immuno-PCR. Immuno-PCR combines ELISA and real-time PCR (RT-PCR) by conjugating the detection antibody to an oligo. The antibody detects the analyte, and the amount of associated oligo can be quantified with RT-PCR. Immuno-PCR is extremely sensitive and can detect analytes in the pg-fg range, as well as being highly amenable to multiplexing with the use of multiple unique oligos. Multiple vendors now offer conjugation services and kits.

Immunofluorescence. In immunofluorescence (IF), fluorescently labeled antibodies are used to detect analytes in a sample that can be visualized with a fluorescence microscope. Traditionally, IF is conducted on a single layer of cells or a thin slice of tissue to determine the distribution of the biomolecule, and only a few analytes can be measured in each sample.

Way forward
The coming years are anticipated to witness continuous innovation and breakthroughs in immunoassay formats, bioanalytical platforms, biosensing concepts, detection devices, and complementary technologies. The next-generation immunoassays, based on highly simplified immunoassay formats, require only minimal process steps and critically reduced sample volumes without any washing steps. They will be fully automated, cost-effective, and equipped with smartphone- or gadget-based mobile healthcare capabilities. Therefore, they can be deployed at centralized, decentralized, remote, and personalized settings with minimal or no requirement for power supply and skilled analysts. The immunoassay trend is strongly inclined toward immunoassay formats to perform multiplex detection of biomarkers for a particular disease and offer clinical diagnosis and monitoring effectively via clinical score. The evolving trend toward smartphone-based immunoassay technologies can extensively extend the outreach of diagnostics by providing personalized mobile healthcare monitoring and management.
