Microdisseção a laser para aplicações de tecido único agnóstico de espécies

Overview

This study presents a technique combining laser capture microdissection with the CEL-Seq2 protocol for generating transcriptomic data from small individual tissue samples. The method facilitates detailed gene expression analysis in C. elegans and can be adapted for non-model species, bypassing the need for species-specific genetic tools.

Key Study Components
