Genomic DNA Extraction Kit (HMW, Magnetic Beads)

The Genomic DNA Extraction Kit (HMW, Magnetic Beads) provides a reliable and fast process for extracting high molecular weight (HMW) genomic DNA from cells, blood, and tissues using Solid Phase Reversible Immobilization (SPRI) magnetic beads. With our proprietary magnetic beads technology, the kit eliminates the tedious centrifuge steps for columns. The kit provides a reliable and simple approach for high-quality genomic DNA isolation with fast magnetic response time and high binding capacity.

The extracted HMW genomic DNA size ranges are dependent on the beads resuspension: 50-150 kb by tube tapping and 40-100 kb by tube vortexing. Purified DNA is recovered at high yield and high purity without RNA contamination. The typical purity ratios of A260/A280 are around 1.8-2.0, and A260/A230 are around 2.2-2.5. Purified HMW genomic DNA is suitable for applications such as long-read sequencing, linked-read genome assembly, long range PCR, optical mapping, and other general applications.

Cultured Cell samples

Cultured cells are collected and are resuspended in a buffer and then lysed with a lysis buffer, then mixed with beads to bind genomic DNA. The samples are mixed with a buffer and after washing steps, genomic DNA is eluted in the Elution Buffer. The isolated genomic DNA with the magnetic beads is free of contamination such as RNA, proteins, salts, and other impurities.

Blood samples

Whole blood is resuspended in the RBC buffer to remove RBC. The remaining leucocytes are lysed with a lysis buffer, then mixed with beads to bind genomic DNA. The samples are mixed with a buffer and after washing steps, genomic DNA is eluted in Elution Buffer. The isolated genomic DNA with the magnetic beads is free of contamination such as RNA, proteins, salts, and other impurities.

Tissue samples

Tissues are homogenized and lysed, then mixed with beads to bind genomic DNA. The samples are mixed with a buffer and after washing steps, genomic DNA is eluted in Elution Buffer. The isolated genomic DNA with the magnetic beads is free of contamination such as RNA, proteins, salts, and other impurities.

Introduction

Free-circulating nucleic acids, such as tumor-specific extracellular DNA fragments and mRNAs in the blood or fetal nucleic acids in maternal blood, are present in serum or plasma usually as short fragments, <1000bp (DNA). HiPure Circulating DNA Midi Kit enables efficient purification of these circulating nucleic acids from human plasma, serum, or urine. The extracted products can be used for clinical in vitro detection.

Principle

This product is based on silica Column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer.

Advantages

• High yield – most optimal process, free DNA (>50bp) can be obtained to the maximum extent
• High concentration – low elution volume, ensuring high nucleic acid concentration
• High purity – low alcohol binding method, completely removing inhibitor and protein pollution
• High recovery – DNA can be recovered at thelevel of PG by silica gel column purification

Storage and Stability

Proteinase K, Carrier RNA should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

Introduction

This product supplies a simple and rapid extraction of total RNA including microRNA from Blood, buffy coat, bone marrow, Cell suspension and other body fluids. The kit is based on superparamagnetic particles purification technology, no phenol-chloroform extraction or alcohol precipitation. Purified RNA is ready for downstream applications such as RT-PCR, virus RNA testing and so on.

Details

Principle

The Kit can be used for both manual extraction process and automatic nucleic acid extraction machines. This Kits is suitable for extracting RNA from ≤ 1 x10⁶ cells suspension, 50 μl Whole Blood, 50μl buffy coat, 20μl bone marrow. This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Protease. RNA/DNA is released into the lysate. After adding magnetic particles and binding solution, DNA/RNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were digested using DNase and washed with washing buffer to remove proteins and impurities, washed with ethanol to remove salts, and
