The global ELISpot and Fluorospot assay market was valued at USD 311.8 million in 2024 and is projected to reach USD 450.0 million by 2030, expanding at a CAGR of 6.3% from 2025 to 2030. This steady growth is driven by the increasing prevalence of chronic and infectious diseases, the expansion of drug discovery initiatives, and the rising utilization of these assays in both diagnostics and biomedical research. Additionally, growing application in pre-clinical and clinically regulated bioanalysis is contributing significantly to market expansion.

ELISpot and Fluorospot assays play a critical role in evaluating immune responses, particularly in understanding how various diseases, including cancer, interact with the immune system. These assays are instrumental in detecting and analyzing naturally occurring tumor-reactive T-cells, which are key players in cancer immunotherapy. Their use spans across epitope mapping, identification of tumor antigens, and monitoring of vaccine-induced T and B-cell responses.

The assays have proven valuable in the development of treatments for cancers such as hepatocellular carcinoma (HCC) and cervical cancer, both of which are strongly linked to infections with hepatitis B virus (HBV) and human papillomavirus (HPV), respectively. For instance, the ELISpot assay has been utilized to assess HPV vaccines in mice and cell lines by measuring IFN-γ and IL-2 responses.

In metastatic cervical cancer cases, the detection of antigen-specific T-cell responses through IFN-γ ELISpot has enabled researchers to craft novel therapeutic approaches. These include the induction of tumor-specific cytotoxic T lymphocytes (CTLs) via dendritic cells loaded with tumor DNA or homogenates, and the creation of virus-vectored vaccines, such as adenovirus vectors encoding tumor antigens. The effectiveness of these tumor-specific CTL responses is often evaluated using ELISpot assays.
