The E.Z.N.A.® DNA/RNA Isolation Kit is designed for the simultaneous isolation of both genomic DNA and total RNA from the same cells or tissues. The sample is first lysed and homogenized in a special denaturing buffer, spun to pellet RNA and undigested particles, and then the supernatant is applied to a HiBind® DNA spin column to bind DNA. The RNA pellet is dissolved and purified by a HiBind® RNA spin column. Since there is no need to divide the sample into two parts for separate purification procedures, maximum yield of DNA and RNA can be purified from the entire sample.

Genomic DNA and total RNA purified using the E.Z.N.A.® DNA/RNA Isolation Kit. DNA/RNA was extracted from tissue samples. DNA (5% of total purified DNA) was analyzed on a 0.8% agarose gel. Total RNA (10% of total purified RNA) was analyzed on a 1% agarose gel to demonstrate yield and quality of the DNA/RNA. Sample 1 from mouse liver, sample 2 from mouse kidney, sample 3 from mouse spleen, sample 4 from HeLa cells, and sample 5 from cos-7 cells.
