Inflammation is involved in many fields including cosmetology, drug discovery (including RNA-based vaccines), and diagnostic index development, as well as being linked to almost every disease such as HIV, cancers, or neurodegenerative diseases. For this reason, analysis of the inflammasome is a major concern. Immunoassays are a classic and affordable method to quantify the corresponding proteins secreted by cells during inflammation. Nevertheless, there are well-known drawbacks and limitations raising key questions about the sensitivity, reproducibility and even the universality of the results. We can’t all use mass spectrometry, but fortunately, ELISA tests and multiplexing have evolved. Let’s discover how much.
