The field of personalized medicine has made enormous progress in recent years. Scientists are gaining deeper understanding of how a person's genetics can impact diseases and treatment outcomes. By studying biomarkers like proteins, physicians can gain valuable insights into what treatment approach may work best for each individual patient. This momentum toward tailored healthcare is driving strong demand for immunohistochemistry testing.
Testing tumor tissue samples through immunohistochemistry (IHC) staining allows doctors to examine the presence of specific biomarkers. This reveals whether certain targeted therapies may be effective or whether a patient is likely to respond poorly to a standard treatment approach. As personalized medicine becomes more prevalent, immunohistochemistry is playing a critical role in helping physicians develop personalized care plans and choose the most appropriate intervention for each patient.
The ability to analyze patient samples and identify biomarker expressions is fueling the tailoring of treatments at the molecular level. More healthcare organizations are incorporating IHC into standard practice to facilitate data-driven clinical decision making on a personalized basis.
Market players are actively focusing on partnerships and collaborations, which is expected to drive the growth of the global immunohistochemistry market over the forecast period.
At the AACR Annual Meeting in April 2025, Agilent announced a strategic collaboration with Abcam to develop novel IHC companion diagnostics (CDx) using Abcam’s extensive portfolio of over 10,000 recombinantly‑derived monoclonal antibodies (RabMAbs®). This partnership aims to accelerate the creation and deployment of custom IHC assays for both drug development and early-stage clinical trials.
The rising global incidence of cancer and other chronic diseases is driving increased demand for precision diagnostics using IHC biomarkers. Furthermore, an aging population prone to age-related diseases will require more diagnostic testing. Newly discovered protein biomarkers continue to expand the clinical applications of IHC. Automation and multiplex assays promise to increase throughput and lower turn thus, creating lucrative opportunities for market growth over the forecasted period.
In 2024, Biocare Medical collaborated with Molecular Instruments to incorporate Hybridization Chain Reaction (HCR) imaging technology into its automated IHC/ISH platforms, increasing spatial resolution and multiplexing capability. The collaboration is intended to provide high-throughput, in situ hybridization and IHC workflows with enhanced signal clarity and cost-effectiveness.
