With the emergence of more sophisticated techniques for gene expression analysis (e.g. microarray analysis, real-time RT-PCR), the quality of the RNA samples being studied becomes increasingly critical. As The RNA Company^®, Ambion is committed to providing the highest quality RNA available. To achieve this goal it is necessary to understand what "high quality RNA" truly means with respect to various downstream applications. Intactness of mRNA, genomic DNA contamination, presence/absence of enzymatic inhibitors, and ribosomal RNA contamination in poly(A) preparations are all important aspects of RNA quality. As we continue to gain a better understanding of how these factors affect downstream applications, we will strive to ensure that our FirstChoice RNA products exceed the requirements for even the most stringent applications.

FirstChoice Tumor RNA includes 5 µg of total RNA from an individual human tumor. Each product is derived from a single donor and has not been pooled with other RNA. All FirstChoice RNA is subjected to the same stringent Quality Control standards including analysis of integrity and stability by capillary electrophoresis using the Agilent 2100 bioanalyzer. Because of the small size of each individual tumor, RNA availability is limited. Please call for more information.
