(Summary description)New Product Launching | Blood RNA-Seq "New Partner" is online! Background Information As a medium for receiving, transmitting and responding to numerous biological signals, blood is involved in the metabolism, monitoring, maintenance of metabolism and immune function of almost all cells, tissues and organs. It is an easy-to-obtain clinical sample and it plays a vital role in the research of blood diseases, immunity, cancer, endocrine and other aspects. The rRNA content in total RNA of peripheral blood is more than 90%, and Globin mRNA accounts for about 70% of mRNA. These RNA genes can provide less effective information. The direct use of blood for sequencing not only produces a lot of worthless data, but also affects the detection of low abundance mRNA. Therefore, the effective removal of rRNA and Globin mRNA is the first important step for RNA library construction.  Product Description Ribo-off Globin & rRNA Depletion Kit (Human/Mouse/Rat) (N408) is for Blood Total RNA samples, through the steps of the hybridization of Globin mRNA and rRNA with probe, RNase H depletion, DNase I depletion and other steps, finally they are removed from Total RNA, and other mRNAs and non-coding RNAs are retained, which can be used for the analysis of non-coding RNAs such as LncRNA. Applicable sample types are abundant, compatible with low starting amount (0.01-1 μg) and low-quality samples.
