[QP5220] Q-PAGE™ TGN Precast Gel (Midi, 15 wells, 10%), 10 gels

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.

Overview

• Isolate all sizes of circulating and exosomal RNA, including microRNA
• Versatile urine input ranges
• No phenol extractions
• No carrier RNA
• Bind and elute all RNA irrespective of size or GC content, without bias
• Concentrate circulating RNA and exosomal RNA into flexible elution volumes
• Purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix

These kits provide a fast, reliable and convenient method to purify and concentrate high quality, high purity and inhibitor-free cell-free circulating RNA, including exosomal RNA as well as viral RNA from fresh, preserved or frozen urine samples. All components for the purification are provided in one convenient and fast kit for the easy processing of small input volumes of bodily fluids. The purified urine RNA is fully compatible with all downstream applications including PCR, qPCR, methylation-sensitive reverse transcription qPCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, expression array assays, and NGS.

Background

Recent evidence indicates that cell-free circulating RNA (cf-RNA) including exosomal RNA in urine contains valuable information for the discovery of biomarkers that can help for the early detection of certain cancer types and for monitoring the disease status as well as for the detection of any infectious pathogens. Exosomes can be found in saliva, blood, urine, amniotic fluid and malignant ascitic fluids, among other biological fluids. Evidence has been accumulating recently that these vesicles act as cellular messengers, conveying information to distant cells and tissues within the body. These exosomes may play a functional role in mediating adaptive immune responses to infectious agents and tumours, tissue repair, neural communication and transfer of pathogenic proteins. For this reason exosomal RNAs may serve as biomarkers for various diseases including cancer. The advantage for using urine as a source for cancer biomarkers is that it can be acquired in large quantities without using invasive procedures. In addition, repeated sampling from the same individual is applicable, which facilitates longitudinal studies. There are many advantages favouring the use of urinary nucleic acid for cancer biomarker discovery over blood, tissue samples or other bodily fluids, including: (1) urine is non-infectious for HIV and less infectious for many other pathogens; (2) the profile of urinary nucleic acid is similar to that in plasma or serum but with a lower concentration; (3) Nucleic acid purification from urine is technically much easier because of its low protein concentration (1000-fold lower than blood).

The hydrogen peroxide Assay Kit provides a simple robust method for the measurement of hydrogen peroxide. This kit utilizes a highly sensitive Megaplex Red probe which in the presence of horseradish peroxidase (HRP), allows for the measurement of H₂O₂ in a sample. Upon oxidation of the probe by HRP, a coloured product (resorufin) is formed that can be measured in fluorescence mode using excitation in the range 530-560 nm and emission at ~ 590 nm or colourimetrically at 570 nm. The excitation and emission maxima of Megaplex Red are 571 nm and 585 nm respectively.
