Library Preparation

This unit presents protocols for construction of next-generation sequencing (NGS) directional RNA sequencing libraries for the Illumina HiSeq and MiSeq from a wide variety of input RNA sources. The protocols are based on the New England Biolabs (NEB) small RNA ...

RNA-sequencing (RNA-seq) is rapidly emerging as the technology of choice for whole-transcriptome studies. However, RNA-seq is not a bias free technique. It requires large amounts of RNA and library preparation can introduce multiple artifacts, compounded by problems from later stages ...

from Cofactor Genomics 1. Sample Quality and and stringent QC measures First and foremost, if a sample is of low quality or complexity, both of which can occur due to degradation, then it is best to either not sequence or ...

Next-generation sequencing (NGS) is becoming one of the most widely used technologies in the field of genomics. Library preparation is one of the most critical, hands-on, and time-consuming steps in the NGS workflow. Each library must be prepared in an ...

The production of DNA libraries in sufficient quantity and quality is not only the actual sequencing of the essential step in order to achieve meaningful results in accordance with Next Generation Sequencing (NGS ) process . Automated methods must be ...

High-throughput sequencing, also known as next-generation sequencing (NGS), has revolutionized genomic research. In recent years, NGS technology has steadily improved, with costs dropping and the number and range of sequencing applications increasing exponentially. Here, researchers from The Scripps Research Institute ...

Researchers at Stanford University present a simple molecular indexing method for quantitative targeted RNA sequencing, in which mRNAs of interest are selectively captured from complex cDNA libraries and sequenced to determine their absolute concentrations. cDNA fragments are individually labeled so ...

Next-generation sequencing (NGS) has caused a revolution in biology. NGS requires the preparation of libraries in which (fragments of) DNA or RNA molecules are fused with adapters followed by PCR amplification and sequencing. It is evident that robust library preparation ...

Recent advances in RNA-seq methodologies from limiting amounts of mRNA have facilitated the characterization of rare cell-types in various biological systems. So far, however, technical variations in these methods have not been adequately characterized, vis-à-vis sensitivity, starting with reduced levels ...

Priming of random hexamers in cDNA synthesis is known to show sequence bias, but in addition it has been suggested recently that mismatches in random hexamer priming could be a cause of mismatches between the original RNA fragment and observed ...
