Animal: 28S:18S RNA ≥ 1. developed a drug discovery platform, digital RNA with pertUrbation of Genes (DRUG-seq), a massively parallel, automated, low-cost next-generation sequence-based approach, which can analyze the changes of the whole transcriptome under chemical and genetic perturbations, and it has been successfully. Learn More. Gierahn TM, et al. Droplet-based single-cell RNA-seq has emerged as a powerful technique for massively parallel cellular profiling. et al. ARTICLE Single-cell RNA-seq of rheumatoid arthritis synovial tissue using low-cost microfluidic instrumentation William Stephenson 1, Laura T. Something of a misnomer because all the libraries end up as DNA, but this refers to the starting material. Technical advances in single-cell RNA sequencing and. Many of the methods, particularly sci-RNA-seq, would be more cost effective with larger numbers of single cells or nuclei 13. Single-cell RNA-Seq can precisely resolve cellular states but application to sparse samples is challenging. Third, RNA-seq is much more sensitive than microarray-based methods in detecting low and high expressed genes. Here, we present a simple RNA sequencing protocol with substantially reduced costs.
