Abstract: The disclosure provides methods for isolating nucleic acids from a biological fluid. In one aspect, the disclosure provides a method for isolating RNA. In another aspect, the disclosure provides a method for isolating DNA. In one aspect, the methods described herein utilize a protocol that combines a detergent-based initial denaturation, protease digestion, and organic extraction followed by column purification that maximizes RNA/DNA yield and preserves RNA/DNA integrity. In yet another aspect, the disclosure provides a kit for isolating RNA and/or DNA.
