Deciphering the Early Mouse Embryo Transcriptome by Low-Input RNA-Seq

subject

description

Early preimplantation embryos are precious and scarce samples that contain limited numbers of cells, which can be problematic for quantitative gene expression analyses. Nonetheless, low-input genome-wide techniques coupled with cDNA amplification steps have become a gold standard for RNA profiling of as minimal as a single blastomere. Here, we describe a single-cell/single-embryo RNA sequencing (RNA-seq) method, from embryo collection to sample validation steps prior to DNA library preparation and sequencing. Key quality controls and external Spike-In normalization approaches are also detailed.
