title: GSM8293889: heart left ventrical,MI,rep4; Mus musculus; RNA-Seq
library_construction_protocol: Total RNA was extracted using the Magzol reagent (Magen, R480102) and 1μg of RNA was used for the construction of sequencing libraries. A certain amount of RNA samples are denatured at suitable temperature to open their secondary structure, and mRNA is enriched by oligo (dT) -attached magnetic beads.The reaction system is configured. After reacting at the suitable temperature for a fixed period of time, RNAs are fragmented.Prepare the first-strand synthesis reaction system, and set up the reaction program, synthesize the first- strand cDNA, prepare the second-strand synthesis reaction system, and set up the reaction program to synthesize the second-strand cDNA.After the reaction system and program are configured and set up, double-stranded cDNA fragments are subjected to end-repair, and then a single 'A' nucleotide is added to the 3' ends of the blunt fragments. The reaction system and program for adaptor ligation are subsequently configured and set up to ligate adaptors with the cDNAs.The PCR reaction system and program are configured and set up to amplify the product.
