The area of gene expression reagents is one of the newest and most important sectors of pharmaceutical and bioscience research and development. The term gene expression reagents refers to chemicals that are used in gene expression experiments that are performed to determine whether a particular gene is expressed—i.e., present—and in some cases at what levels, in a biological sample. The purpose of this TriMark Publications report is to describe the specific segments of the global gene expression reagents market. Within this area, the study covers those segments that are highly active in terms of innovation and growth. Specifically, this review examines the markets for gene expression reagents and small lab equipment all the way up to highly automated platforms. Emphasis is on those companies that are actively developing and marketing gene expression reagents for genomics research in the academic sector and the pharmaceutical, bioscience industry. This study concentrates on the laboratory reagent market segment and the companion gene expression reagents sector in the U.S. and around the world that use materials for genetic research. Particular attention is paid to those areas of the gene expression reagents sector that are showing the greatest growth or the most innovation.
