Purification of high-quality RNA from synthetic polyethylene glycol-based hydrogels.


ABSTRACT: Polyethylene glycol (PEG)-based hydrogels, with variable stiffness, are widely used in tissue engineering to investigate substrate stiffness effects on cell properties. Transcriptome analysis is a critical method for understanding cell physiology. However, significant RNA degradation was observed during the process of isolating and purifying RNA from cells encapsulated in the PEG hydrogel, thereby precluding purification of high-quality RNA. Here, we describe a simple protocol that prevents RNA degradation and improves the quality and yield of RNA isolated from cells cultured in PEG hydrogels. This modification produces high-quality total RNA suitable for RNA sequencing and microarray analysis.
