ELISpot and FluoroSpot assays are widely used to assess immune responses, making them increasingly important for understanding disease mechanisms, particularly in oncology. These assays enable the detection and characterization of naturally occurring tumor-reactive T cells, which play a crucial role in cancer immunotherapy. In addition, they are utilized for epitope mapping, tumor antigen identification, and monitoring vaccine-induced T- and B-cell responses. Certain cancers, such as hepatocellular carcinoma and cervical cancer, are closely associated with high-risk viral infections, including hepatitis B virus (HBV) and human papillomavirus (HPV). Tumor-specific vaccines are frequently evaluated in animal models and cell lines, with the IFN-γ and IL-2 ELISpot assays commonly employed, as demonstrated in HPV vaccine research.

The IFN-γ ELISpot assay is also instrumental in detecting antigen-specific T-cell responses in patients with metastatic cervical cancer, supporting the development of novel therapeutic strategies. Researchers are exploring approaches to suppress cancer progression by inducing tumor-specific cytotoxic T lymphocytes through dendritic cells loaded with tumor DNA or tumor homogenates. Virus-vectored genetic vaccines, such as adenovirus vectors encoding tumor antigens, are another area of active research, with ELISpot assays used to measure tumor-specific CTL responses.

Furthermore, the IFN-γ ELISpot assay is applied to evaluate the immunological efficacy of high-dose IL-2 therapies in patients with metastatic melanoma and renal cell carcinoma. The expanding use of ELISpot and FluoroSpot assays in cancer research is expected to support market growth, particularly as global cancer incidence continues to rise. According to data from the National Cancer Institute, annual cancer cases are projected to reach 29.9 million, with cancer-related deaths expected to increase to 15.3 million, underscoring the growing need for advanced immunological assessment tools.

Beyond oncology, ELISpot assays serve as valuable tools for evaluating the impact of drug candidates on the immune system. They are increasingly recognized as critical components of vaccine development programs targeting diseases such as AIDS, malaria, tuberculosis, cancer, and influenza. ELISpot tests are widely used in clinical studies to assess vaccine efficacy. According to the World Health Organization’s International Clinical Trials Registry Platform, 54,952 clinical trials were conducted globally in 2022, highlighting the scale of ongoing research activities that are expected to further drive demand for ELISpot and FluoroSpot assays.
