EasyPrep Total RNA Kit provides a new RNA isolation technology based on Guanidine Thiocyanate/ Phenyl method. It contains a unique buffer RBZ that minimizes the contamination of genomic DNA and protein. This Kit efficiently isolates high pure RNA from blood, cells, tissues, and plant samples in one hour. The purified RNA is ready-to-use in downstream applications such as RT-PCR and real-time RT-PCR, gene-chips assay, northern blot, poly-A screening, in vitro transcript, and molecular cloning.
