title: GSM6635230: ExpA-st12.5; Xenopus laevis; RNA-Seq
library_name: GSM6635230
library_construction_protocol: Total RNA was extracted using the standard Trizol protocol. 500 ng total RNA per sample was used, poly-A selection and RNA-sequencing library preparation was done using non strand massively-parallel cDNA sequencing (mRNA-Seq) protocol from Illumina, the TruSeq RNA Library Preparation Kit v2, Set A (Illumina #RS-122-2301) according to manufacturer's recommendation. Quality and integrity of RNA was assessed with the Fragment Analyzer from Advanced Analytical by using the standard sensitivity RNA Analysis Kit (Advanced Analytical #DNF-471). All samples selected for sequencing exhibited an RNA integrity number over 8. For accurate quantitation of cDNA libraries, the QuantiFluor™dsDNA System from Promega was used. The size of final cDNA libraries was determined using the dsDNA 905 Reagent Kit (Advanced Bioanalytical #DNF-905) exhibiting a sizing of 300 bp on average. Libraries were pooled and paired-end 100bp sequencing on a HiSeq4000 was conducted at the Vincent J. Coates Genomics Sequencing Lab, University of California at Berkeley.
