Abstract

Current N<sup>6</sup>-methyladenosine (m<sup>6</sup>A) mapping methods need large amounts of RNA or are limited to cultured cells. Through optimized sample recovery and signal-to-noise ratio, we developed picogram-scale m<sup>6</sup>A RNA immunoprecipitation and sequencing (picoMeRIP-seq) for studying m<sup>6</sup>A in vivo in single cells and scarce cell types using standard laboratory equipment. We benchmark m<sup>6</sup>A mapping on titrations of poly(A) RNA and embryonic stem cells and in single zebrafish zygotes, mouse oocytes and embryos.
