RecruitingDevice studyDeveloping Remote Human Milk Collection as a Novel Technique for Transcriptome SequencingThis study will develop a protocol for remote human milk collection for use in gene expression research through application of ribonucleic acid (RNA) preservation reagents. The investigators hypothesize that addition of preservation reagents will preserve RNA in human milk, facilitating downstream analyses that require intact RNA. 50 lactating participants will be recruited and requested to provide reagent-mixed samples to be sent to the university through shipping services where they will be evaluated for RNA quantity, quality and profile.
