Recent advances in microfluidics and cDNA barcoding have led to a dramatic increase in the throughput of single-cell RNA-Seq (scRNA-Seq) [1,2,3,4,5]. Single-cell RNA-sequencing (scRNA-seq) has been widely adopted in recent years due to standardized protocols and automation, reliability, and standardized bioinformatic pipelines. Both platforms cannot. Provides sensitive, accurate measurement of gene expression. 1983;25:263–9. g. Two types of libraries were prepared by using 4 ng or 250 pg RNA from each sample. Single-cell RNA-seq can precisely resolve cellular states, but applying this method to low-input samples is challenging. Molly Martorella 1,2 *, Silva Kasela 1,2, Renee Garcia-Flores 1,3, Alper Gokden 1, Stephane E. Low cost. RNA-Seq of Low-Quality and FFPE Samples. We present TEQUILA-seq, a versatile, easy-to-implement, and low-cost method for targeted long-read RNA-seq utilizing isothermally linear-amplified capture. NGS technologies comprise high throughput, cost efficient short-read RNA-Seq, while emerging single molecule, long-read RNA-Seq technologies have. With the introduction of cost effective, rapid, and superior quality next generation sequencing techniques, gene expression analysis has become viable for labs conducting small projects as well as large. It provides deeper insights into 3’ and 5’ gene expression and characterizes cell differences, at a single-cell resolution. Next-generation sequencing: methodology and application. Here, we present Seq-Well, a portable, low-cost platform for massively parallel single-cell RNA-seq. Overall, GT-seq can be effectively applied to low-quality DNA samples, minimizing the inefficiencies presented by exogenous DNA typically found in minimally invasive samples. Low-throughput library prep. Here, we describe a low-cost, semi-automated pipeline to extract cell-free RNA using one of two commercially available, inexpensive and open-source robotic systems: the Opentrons OT1. Single cell RNA sequencing (scRNA-seq) represents a new large scale and high throughput technique allowing analysis of the whole transcriptome at the resolution of an individual cell.
