Western blotting is a technique used to analyze individual proteins in a blood or tissue sample. This technique uses gel electrophoresis to separate a sample’s proteins based on their size, charge, and other characteristics. It offers numerous benefits over other techniques like ELISA. Western blotting allows the detection of several targets, semi-quantifies the protein of interest, and determines the size of the target protein.
Numerous factors govern market growth, including the rising prevalence of chronic disorders and growing research and development activities. The burgeoning biotech sector and advancements in proteomics augment market growth. The increasing investments and collaborations among academic researchers and key players promote the development of Western blotting. Government organizations launch initiatives to encourage early disease diagnosis.
Artificial intelligence (AI) can transform the Western blotting technique by introducing automation in the entire workflow. AI enhances efficiency and accuracy, as well as reduces manual errors during the experiment. It improves reproducibility and streamlines the entire process. It plays a major role in the detection and analysis of outcomes. AI-based detectors can decipher complicated protein patterns that are difficult for researchers. This reduces the time for data interpretation, enhancing the accuracy and precision of data. AI-driven software can revolutionize the image analysis process.
Rising Prevalence of HIV
The major growth factor of the Western blotting market is the rising prevalence of HIV/AIDs. The Western blotting technique is primarily used to detect anti-HIV antibody in a human serum sample. The UNAIDS reported that approximately 39.9 million people were living with HIV globally in 2023, with 1.3 million new cases. (Source - UNAIDS) Numerous government organizations make necessary efforts to access effective HIV prevention, diagnosis, treatment, and care. The UNAIDS also reported that $19.8 billion was available for the AIDs response in low- and middle-income countries as of 2023.
Lack of Skilled Professionals
The Western blotting technique is a labor-intensive protocol, requiring skilled professionals to perform such a complex experiment. Several low- and middle-income countries do not have sufficient skilled professionals to work on Western blotting. The lack of sufficient funding in such countries also restricts market growth.
What is the Future of the Western Blotting Market?
The future of the market is promising, driven by the growing need for miniaturization of the Western blotting technique. Advancements in Western blotting are made with the adoption of microfluidics techniques. Microfluidics results in faster analysis time, improved sensitivity, lower reagent consumption, and higher multiplexing capability. Miniaturization of the Western blot technique reduces sample wastage and enables the detection of minute amounts of samples. This decreases the overall cost of research and analysis. Microfluidic advancements overcome several challenges of the conventional Western blot technique. Furthermore, parallelization of multiple immunoassays can present future opportunities for researchers.
By product, the consumables segment held a dominant presence in the market in 2024. The segment dominated because of the availability of low-cost consumables.
