Since its discovery, the naturally occurring RNA (ribonucleic acid) interference effect has been acclaimed as the most exciting technical breakthrough in biological research in the last decade. Some industry analysts predict that RNA interference (RNAi) may even surpass PCR as a top technology. RNAi allows scientists to silence the expression or effect of a gene under study. This is known as gene knockdown. This field has rapidly emerged as a fast-growing new market. The purpose of this TriMark Publications report is to review the market for RNAi testing equipment and supplies. RNAi is a mechanism in molecular biology where the presence of certain fragments of double-stranded RNA (dsRNA) interferes with the expression of a particular gene which shares a similar sequence with the dsRNA. This study defines the dollar volume of sales, both worldwide and in the U.S., and analyzes the factors that influence market size and growth for RNAi testing. The main objectives of this study are to: 1) understand the different sectors of RNAi testing market and to look at a description of the instruments, reagents and supplies marketed by major companies in each segment; 2) obtain a complete understanding of the individual RNAi-testing platforms—from basic principles to clinical applications; 3) discover feasible market opportunities by identifying high-growth applications in different analytical diagnostic areas, with a focus on the biggest and expanding markets; 4) focus on global industry developments and trends through an in-depth analysis of the major world markets for RNAi measurement technology, including growth forecasts; and 5) present market figures related to the current value of RNAi testing, market projections, market share, key players and sector growth rates.
