The rising adoption of these protein labeling products for post-translational modification studies in the investigation of biological functions as well as normal cell functioning, the rising adoption of sophisticated bioengineering techniques in various technologies, and the growth in the prevalence of chronic diseases such as cancer and the need for diagnosis drive the protein labeling market. An increase in chronic diseases globally is also aiding the market growth. There has been an increase in R&D activities by many healthcare companies to develop novel products.
Test that includes western blotting, ELISA, immunohistochemistry, immunocytochemistry, and flow cytometry requires protein labeling methods for various medical and clinical studies. There is an availability of multiple labels in the market for multiple applications, and the type of name and labeling strategy used must be carefully selected for each application. The surge in demand for genome sequencing and proteomics research is fueling the market’s growth. Moreover, the increase in research and development of novel vaccines and the availability of technologically advanced products by key players are also expected to play a vital role in the market’s growth.
The skillful professional’s limited availability is expected to hamper the market’s growth.
However, the limited availability of skillful professionals in the current scenario, increased competition among key players for launching advanced products, and limited product applications may hinder the growth of the market.
The high cost of protein labeling is also a leading factor for restrained growth, as chemical labeling has a drawback that the protein that has been modified can lose one or more activities. So, the labeled protein’s activity should be tested relative to unlabeled protein. Metabolic labeling also needs purification of the radioactive protein, and over the extended use of cold room equipment and centrifuges, it is difficult to consist the radioactivity.
