Overview

• Genomic DNA can be isolated from as few as 10 bacterial cells in 1 mL of milk
• Isolate genomic DNA from both Gram-negative and Gram-positive bacteria in milk
• Can process challenging samples such as mastitic milk
• Inhibitor-free DNA is ready for PCR, qPCR, Southern Blot, sequencing & more
• Fast and efficient spin-column format

This kit provides a rapid spin column method for the isolation and purification of genomic DNA from both Gram-negative and Gram-positive bacteria in milk samples.  It can also be used to process challenging milk samples such as Mastitic milk for example.  The kit is highly sensitive and can isolate DNA from a cell density of as little as 10 bacteria contained in 1 mL of milk.  Genomic DNA is isolated in 45 minutes, free of inhibitors and ready for any number of downstream applications including PCR, qPCR and Southern Blot analysis, sequencing and more.​

Introduction

This kit provides a simple and fast solution for the extraction of circulating nuclear acid from serum, plasma, and other cell-free liquid samples. Circulating nucleic acid refers to the free extracellular nucleic acid produced by cell apoptosis, of which fragments are generally below 1KB. The kit is based on silica gel column purification technology, which is no need for toxic phenol chloroform extraction and time-consuming alcohol precipitation during the extraction. The obtained Circulating Nucleic Acid can be directly used for quantitative PCR, liquid or solid phase chip analysis, hybridization, and SNP detection.
HiPure Circulating DNA/RNA Kit adopts a unique solution system and multiple layers of filter membranes with different pore sizes, which can efficiently process large volumes of serum and plasma samples and capture extremely small amounts of free nucleic acids.

Principle

This kit is based on silica gel column technology. Serum or other liquid samples are lysed and digested in buffer CFL. After adding buffer CFP, the protein is removed by centrifugation to obtain the supernatant. Isopropanol is added to precipitate the total nucleic acid and transferred to the column for filtration. DNA / RNA is adsorbed on the membrane of the column, while the protein is not adsorbed and removed with the filtrate.The column is washed with buffer MGW1 to remove protein and other impurities, and then washed with buffer RW2 to remove salt. Finally, DNA / RNA is eluted by low salt buffer. The eluted DNA / RNA can be directly used for quantitative PCR/ RT-PCR, liquid or solid-phase chip analysis, hybridization and SNP detection.

Advantages

• High yield – most optimized process to obtain maximum free RNA and small RNA
• High concentration – low elution volume (>20μl) to ensure nucleic acid concentration
• High purity – low alcohol combination, completely remove inhibitor and protein pollution
• High recovery – silica gel column technology can recover nucleic acid molecules at the level of PG
• Large volume – 1-2ml serum and plasma samples can be processed at one time
