Fitch1 1Center for Developmental Genetics, New York University, 2Sacred Heart University, 3Baylor School A protocol is described that uses laser microdissection to isolate individual nematode tissues for RNA-sequencing. The protocol does not require species-specific genetic toolkits, allowing gene expression profiles to be compared between different species at the level of single-tissue samples.
