Direct-zol RNA Purification Kits

RNA from TRIzol® in 7 Minutes

The Direct-zol RNA kits provide a streamlined method for the purification of high-quality RNA directly from samples in TRI Reagent® or similar.

The procedure is easy. Simply apply a prepared sample in TRI Reagent® directly to the Zymo-Spin Column and then bind, wash, and elute the RNA. No phase separation, precipitation, or post-purification steps are necessary.
