Immunochemicals are used to analyze various reactions and components of molecular mechanism. They are quality products with high specificity and selectivity and are developed for a wide range of applications in medical, pharmaceutical, and life science research. Immunochemicals are used in drug discovery, therapeutics, imaging, assay components, and as a research tools. They are also used to develop personalized medicine and protein therapeutics and to identify new targets to treat various chronic diseases. The global immunochemicals market is projected to expand at a significant CAGR during the forecast period owing to increasing research and development initiatives, rise in government funding in drug discovery and proteomic research, increase in incidence of chronic diseases, and rise in collaboration between industries and research institutes. Furthermore, increase in demand for personalized medicine and protein therapeutics, increased focus on drugs safety and efficacy, and identification of new targets for disease treatment are likely to boost the expansion of the market. However, high cost and stringent regulatory environment are factors restraining the global immunochemicals market.
