Zymo Research Quick-DNA™ MicroPrep Kit D3020 | 50 Preps with Zymo-Spin™ IC Columns (Capped)

The Zymo Research Quick-DNA™ MicroPrep Kit D3020 is a 50-preparation spin column DNA purification kit — ideal for easy, rapid isolation of total DNA (e.g., genomic, mitochondrial, viral) from a variety of biological sample sources. Whole blood (fresh or stored), buffy coat, buccal cells, cells from culture, saliva, and other biological liquid samples can be processed with these kits. Zymo-Spin Column/Plate technology enables high-quality DNA purification in minutes. PCR inhibitors are effectively removed, and the eluted DNA is ideal for PCR, nucleotide blotting, DNA sequencing, restriction endonuclease digestion, bisulfite conversion/methylation analysis, and other downstream applications. Supplied with Zymo-Spin™ IC Columns (Capped). 50 preparations. Catalog # D3020. The 200-preparation version is available as D3021.

D3020 vs. D3021 — Choosing the Right Kit Size: The D3020 and D3021 are identical Quick-DNA™ MicroPrep Kits in every way — the number of preparations and reagent volumes are the sole differences:

The D3020 is the preferred choice for labs evaluating the Quick-DNA™ MicroPrep Kit for the first time, labs with low sample throughput that would leave a 200-prep kit partially unused before expiration, and any workflow where flexibility to switch protocols or kits between experiments is more important than per-prep cost efficiency.

Broad Sample Compatibility — From Whole Blood to Cultured Cells Whole blood (fresh or stored), buffy coat, buccal cells, cells from culture, saliva, and other biological liquid samples can be processed with these kits. The Quick-DNA™ MicroPrep Kit is designed for biological fluid and cell-based samples — including:

• Whole blood (fresh or stored) — typically yields 1.5–3.5µg DNA per 50µL blood
• Buffy coat — concentrated leukocyte fraction from blood
• Buccal cells — non-invasive swab-based sampling
• Cells from culture — mammalian cell lines and primary cells
• Saliva — direct processing without pretreatment
• Plasma and serum — for circulating DNA
• Other biological liquids — compatible biological fluids

For solid tissue samples requiring Proteinase K digestion, the Quick-DNA™ MicroPrep Plus Kit (D4074) is the recommended upgrade.

Up to 5µg DNA Per Prep — High Yield in Minimal Elution Volume Up to 5µg total DNA is eluted into ≥10µL (6µL minimum) DNA Elution Buffer or water. Human whole blood will typically yield 1.5–3.5µg DNA per 50µL blood sampled. Mammalian tissues already homogenized yield 1–3µg DNA per mg skeletal, heart, and brain tissues. The minimal elution volume of ≥10µL (6µL minimum) produces a highly concentrated DNA eluate — ideal for applications requiring maximum DNA concentration in a small volume, including single-cell genotyping, limited-input sequencing library preparation, and sensitive PCR assays.

Zymo-Spin™ IC Columns — High-Quality DNA in Minutes Zymo-Spin Column/Plate technology enables high-quality DNA purification in minutes. The Zymo-Spin™ IC Column silica membrane selectively binds double-stranded DNA while allowing RNA to flow through — eliminating the need for RNase A treatment and producing RNA-free genomic DNA in a small, concentrated volume ready for immediate use in downstream molecular biology applications.

RNA-Free Genomic DNA — No RNase A Treatment Required The selective chemistry of the Zymo-Spin™ IC Column allows binding of double-stranded DNA while RNA passes through the column — producing RNA-free genomic DNA without RNase A treatment. This simplifies the purification workflow and eliminates the potential for RNase A carryover that could affect downstream RNA-containing applications.

PCR Inhibitor Removal — Eluate Ready for Sensitive Applications PCR inhibitors are effectively removed, and the eluted DNA is ideal for PCR, nucleotide blotting, DNA sequencing, restriction endonuclease digestion, bisulfite conversion/methylation analysis, and other downstream applications. The Genomic Lysis Buffer and wash buffer system effectively removes heme, IgG, and other PCR inhibitors commonly found in blood and biological fluid samples — producing a clean eluate that performs reliably in even the most sensitive PCR, qPCR, and sequencing applications.

DNA Size — High Molecular Weight Fragments Up to and >40kb Quick purification of high-quality DNA from whole blood, plasma, serum, body fluids, buffy coat, lymphocytes, swabs, or cultured cells in less than 15 minutes using Zymo-Spin column technology. DNA size: up to and >40kb. The high molecular weight DNA recovered is suitable for applications requiring intact genomic DNA — including restriction endonuclease digestion, Southern blotting, RFLP analysis, microsatellite analysis, and next-generation sequencing library preparation.

Room Temperature Buffer Storage — No Cold Chain Required All kit components including Genomic Lysis Buffer, DNA Pre-Wash Buffer, g-DNA Wash Buffer, and DNA Elution Buffer are stored at room temperature — simplifying kit storage and making the D3020 practical for field-based or resource-limited settings where cold chain maintenance is challenging. Purified DNA is stored at ≤-20°C.

Extensively Referenced in Published Research The Zymo Research Quick-DNA™ MicroPrep Kit family is one of the most widely cited DNA extraction kit systems in published molecular biology research — referenced across genomics, epigenetics, infectious disease, cancer biology, and clinical research. When a published protocol specifies D3020 or Quick-DNA MicroPrep Kit (50 prep), this is the correct product.
