RT Journal Article SR Electronic T1 Validation of methods for Low-volume RNA-seq JF bioRxiv FD Cold Spring Harbor Laboratory SP 006130 DO 10.1101/006130 A1 Peter A. Combs A1 Michael B. Eisen YR 2014 UL http://biorxiv.org/content/early/2014/06/10/006130.abstract AB Recently, a number of protocols extending RNA-sequencing to the single-cell regime have been published. However, we were concerned that the additional steps to deal with such minute quantities of input sample would introduce serious biases that would make analysis of the data using existing approaches invalid. In this study, we performed a critical evaluation of several of these low-volume RNA-seq protocols, and found that they performed slightly less well in metrics of interest to us than a more standard protocol, but with at least two orders of magnitude less sample required. We also explored a simple modification to one of these protocols that, for many samples, reduced the cost of library preparation to approximately $20/sample.
