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.

No centrifuge needed
No column needed
No vacuum needed
A portion of the extracted genomic DNA samples were loaded on a PFGE gel with a DNA ladder indicated. Sample A: liver tissue; Sample B: intestine tissue; Sample C: whole blood; Sample D: cultured 293T cells.
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.
Fast and easy high throughput processing using either a vacuum manifold or centrifugation
Process all soil types including clay, loam, sandy soils and high humic content soils such as peat, compost and manure
Remove organic substances using the OSR Solution
Remove all humic acid from DNA samples using the Humic Acid Removal plate
Isolate high quality total DNA from all soil types – ready for any downstream PCR, qPCR
Excellent DNA for metagenomic studies
No phenol or chloroform extractions
This kit provides a fast, reliable and simple procedure for high throughput isolation of DNA from all types of soil samples including common soil samples and difficult soil samples with high humic acid content such as compost and manure. A combination of chemical and physical homogenization effectively lyses all microorganisms in the soil sample, and the kit removes all traces of humic acid using the provided Organic Substance Removal (OSR) Solution and Humic Acid Removal plate (HAR). Total genomic DNA can be isolated and purified from all the various microorganisms found in soil, such as bacteria, fungi and algae. The purified DNA is of the highest quality and is fully compatible with downstream PCR and qPCR applications and more for any metagenomic study, as all humic acid substances and PCR inhibitors are removed during the isolation.

AOAC Method 2020.07
The Available Carbohydrates Assay Kit method is suitable for the determination of available carbohydrates (AVCHO) comprising *total digestible starch (TDS) plus maltodextrins, sucrose, D-glucose, D-fructose and lactose. New Improved method receiving ‘First Action’ status: AOAC 2020.07. This method is designed to simulate in vivo conditions in the human small intestine (i.e. a 4 h incubation time with PAA + AMG) in parallel with recent advances in Dietary Fiber (DF) methodology (K-RINTDF: AOAC Method 2017.16) and in accordance with the new (physiological based) definition of DF announced by Codex Alimentarius in 2009. Also, sucrose is hydrolysed with a specific “sucrase” enzyme which (unlike invertase which has been used traditionally for this reaction) has no action on fructo-oligosaccharides (FOS).
* Total digestible starch (TDS) is defined as starch that is digested in a 4 h period and is part of the carbohydrate that is available for digestion and absorption in the human small intestine.
