Overview

• Milk samples are stable for 1 month at room temperature (or 1 week at 37°C) in the Preservation Solution
• Fast and easy processing using a rapid spin-column format
• DNA can be isolated and detected from as little as 100 µL of milk
• Isolate high quality genomic DNA

Norgen’s Milk DNA Preservation and Isolation Kit is an all-in-one solution designed for 1) preservation of DNA in milk samples at ambient temperature; and 2) isolation of high quality DNA within a laboratory setting. The kit is provided with a Preservation Solution that allows for either immediate processing of milk samples, or allows for the storage of the milk samples for up to 1 month at room temperature prior to DNA isolation. Genomic DNA extracted from somatic cells and bacteria found in milk can be used in various applications. The isolated DNA can be used for the detection of biomarkers to diagnose a disease, follow the diseases progress or monitor the effects of a particular treatment. Milk DNA can also be used to diagnose particular types of infections. Milk DNA purified using Norgen’s kit is of the highest quality, and is compatible with a number of downstream applications including PCR, Southern Blot analysis, sequencing and microarray analysis.

Milk DNA Preservative

Norgen’s Milk DNA Preservation Solution is an aqueous storage buffer designed for rapid cellular lysis and subsequent preservation of DNA from fresh specimens. The preservative prevents the growth of Gram-negative and Gram-positive bacteria and fungi, and also inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely. In addition, the preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperature. The components of the preservative allow samples to be stored for 1 month without any detectable DNA degradation.

Kit Specifications
Maximum Milk Input	0.5 mL
Time to Complete 10 Purifications	80 minutes (20 minutes hands on)

Storage Conditions and Product Stability
The Proteinase K should be stored at -20°C upon arrival and after reconstitution. All other solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment.

Storage in Preservation Buffer
1) Storage at -20°C is recommended for archival samples and will provide optimal preservation. The preservation buffer will freeze at -20°C. Samples can be stored indefinitely at -70°C.
2) Samples can be stored at room temperature (25°C) for up to 1 month without significant loss of DNA quality.
3) DNA has also been successfully isolated from samples stored at 37°C 1 for one week.

Introduction

Hipure Microbial RNA kit is suitable for extracting high-purity total RNA from bacterial/yeast culture medium. This kit combines high-efficiency Magzol Reagent (one-step extraction reagent) and silicagel column purification technology to complete the extraction of high-purity total RNA in only 40 minutes. The obtained RNA can be directly used in RT-PCR, Northern blot, poly-A + purification, nucleic acid protection and in vitro translation.

Principle

Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.

Advantages

• Fast – several samples can be extracted in 30 minutes
• High purity – the purified RNA can be directly used in various downstream applications
• High recovery – RNA can be recovered at the level of PG
• Good repeatability – silica gel column purification technology can obtain ideal results every time
• Broad spectrum – it can deal with various bacteria, including Gram-positive bacteria that are difficult to be lysed
• Sufficient components – the kit contains carried wall breaking enzymes and glass beads

Storage and Stability

Buffer PHC should be stored at 2–8°C upon arrival. DNase I should be stored at -20°C. However, short-term storage (DNase I up to 1 weeks, Buffer PHC up to 12 weeks) at room temperature(15–25°C) does not affect their performance. The remaining kit components can be stored at roomtemperature (15–25°C) and are stable for at least 18 months under these conditions.
