The western blot, also sometimes referred to as a protein immunoblot, is an analytical technique that makes use of a sample of tissue extract to detect specific protein in it. What makes western blotting an integral part of molecular diagnostics is the fact that it generates sizeable revenue for the global molecular diagnostics market. The western blotting market itself is one that is rapidly expanding. The western blotting technique has gained acceptance among diagnosticians and clinicians over the recent years, and the technique continues to find increasing use thanks to factors such as a growing prevalence of HIV coupled with greater research in proteomics.
A report published by Persistence Market Research states that in 2014, the market for western blotting had a valuation of US$510.1 Mn. The western blotting market held 25% of the molecular diagnostics market in 2014. Moreover, the contribution of the western blotting market to the larger molecular diagnostics market is only expected to rise, say PMR analysts. According to PMR’s projections, by 2021, the western blotting market will contribute US$725 Mn by way of revenue to the global molecular diagnostics market. This translates to a CAGR of 5.4% (in value) from 2015 through 2021.
North America Holds Leading Position in Global Western Blotting Market, to Maintain Dominance Through 2021
Factors that have enabled North America to emerge as the leading regional market for western blotting are a growing prevalence of HIV as well as an escalating demand for accurate diagnosis in areas such as food and beverages, scientific research, medical research, and agriculture. These factors will aid the North America western blotting market to register a healthy CAGR. North America constituted 30% of the global western blotting market in 2014.
Besides North America, Asia and Latin America are the two other regional markets that will exhibit massive growth. While Asia Pacific will exhibit a CAGR of 6.2% from 2015 to 2021, Latin America will log a 6.0% CAGR during the same period.
The use of reagent kits is expected to increase steadily over the next few years, making them the most dominant segment of the western blotting market by product. However, electrophoresis blotting systems will represent the fastest-growing segment in the global western blotting market by product type.
Demand for Manual Techniques to Dwindle with Simultaneous Rise in Use of Automated Blotting Systems
The manual technique for western blotting demands not just time, but a considerable amount of energy. Moreover, continuous supervision is a prerequisite for the manual technique, making it imperative to deploy skilled personnel for the task. In contrast, the automated western blotting technique is faster and doesn’t need extensive supervision. With automation bringing increased efficiency in shorter turn times to the western blotting process, the use of automated western blotting techniques is expected to rise dramatically. However, several clinicians and diagnosticians remain unconvinced about the trustworthiness of outcomes of automated western blotting tests, which is slowing down the rate of their adoption.
Currently, players that hold an appreciable share in the global western blotting market are: Thermo Fisher Scientific, Inc., Hoffmann-La Roche Ltd., GE Healthcare, EMD Millipore Corporation, Danaher Corporation (Lumigen, Inc.), PerkinElmer Inc., Bio-Rad Laboratories, Inc., Bio-Techne Corporation (ProteinSimple Inc.), LI-COR, Inc., and Advansta, Inc.
