title: GSM4822558: MMTV-PyMT tumor_PBS rep2; Mus musculus; RNA-Seq
library_construction_protocol: Endothelial cells were sorted with FACS aria II (BD bioscience). RNA was extracted with Rneasy mini kit (Qiagen).  NEBNext® Ultra™ II Directional RNA Library Prep Kit (New England BioLabs) was used for the construction of sequencing libraries. RNA libraries were prepared for sequencing using standard Illumina protocols
