Zyagen Universal Reference Total RNA is composed of highly pure intact total RNA isolated from wide variety of male & female tissues. Total RNA is extracted using modified guanidine thiocyanate method, treated with DNase & packed at a concentration of 1mg/ml. Features: High quality intact RNA without genomic DNA contamination. Consistent control for standard data set comparisons. Extracted from large variety of male & female tissues for broad gene coverage. Made at industrial scales to minimize lot-to-lot variation Quality Control: The integrity of RNA sample as indicated by intact ribosomal RNA is verified by agarose gel electrophoresis. The purity of RNA is assessed by NanoDrop (A260/A280: 1.9-2.1). Residual DNA contamination is tested by PCR. Applications: Reference RNA is ideal for microarray analysis, Northern blotting, ribonuclease protection assay, SI nuclease assay, RT-PCR/Q-PCR/RACE analysis, cDNA synthesis, microRNA studies, & purification of mRNA for library construction.
