Total RNA extraction. Total RNA for Whole Genome Expression can be isolated using following methods: Cells grown in suspension: TRIzol® Reagent (Cat#15596-018), Invitrogen followed by RNeasy® Mini Kit see RNA Clean Up in the handbook (Cat#74104) Qiagen RNeasy Lipid Tissue Kit see special protocol for cells in the handbook (Cat#74104) Qiagen. Make sure not to use carrier RNA in the purification. AllPrep DNA/RNA Mini Kit- see special protocol for Simultaneous Purification of Genomic DNA and Total RNA from Animal Cells in the handbook (Cat#80204) Qiagen. FACS sorted cells: Sort cells into RLT buffer included in the RNeasy Mini Kit (Cat#74104) Qiagen, continue on to purification. Make sure not to use carrier RNA in the purification. Tissue (fresh or frozen): TRIzol® Reagent (Cat#15596-018), Invitrogen followed by RNeasy® Mini Kit see RNA Clean Up in the handbook (Cat#74104) Qiagen RNeasy Lipid Tissue Kit see special protocol for tissue in the handbook (Cat#74104) Qiagen. Make sure not to use carrier RNA in the purification. AllPrep DNA/RNA Mini Kit - see special protocol for Simultaneous Purification of Genomic DNA and Total RNA from Animal Tissue in the handbook (Cat#80204) Qiagen. SCIBLU Genomics_140902
