Overview
RNA/microRNA/DNA/Proteins are preserved for more than 2 years at room temperature in Norgen’s Urine Preservative
Compatible with most DNA, Total RNA, microRNA and protein isolation methods
Preservative is available in a single dose liquid format (ampule)
Preservative is also available in a dried format in tubes – Urine Collection and Preservation Tubes
Urine Collection and Preservation Devices are available in 4 convenient sizes: 5 cc tubes, 15 cc tubes, 50 cc tubes, and 120 cc cups
Norgen’s Urine Preservative is designed for the rapid preservation of DNA, RNA, microRNA and proteins from fresh urine samples. In addition, the Urine Preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperatures. The components of the Urine Preservative allow samples to be stored for over 2 years at room temperature with no detected degradation of urine DNA, RNA or proteins.
Norgen’s Urine Preservative is available in 2 convenient formats:
1. Urine Preservative Single Dose Ampules With this product Norgen’s Urine Preservative is supplied in a liquid format in single dose ampules. The user simply collects 5 – 50 mL of urine into a urine collection container and adds the contents of the Urine Preservative Single Dose (Cat# 18126). The urine and preservative are then mixed, and the urine nucleic acids and proteins are preserved at room temperature.
2. Urine Collection and Preservation Tubes Norgen’s Urine Preservative is also available in a dried format in Norgen’s Urine Collection and Preservation Tubes. The user simply collects urine into the tubes and mixes gently until the orange preservative pellet in the tube has dissolved. Norgen’s Urine Collection and Preservation Tubes are available in 3 convenient sizes:
Select Urine Tested with the Norgen Urine Collection and Preservation Tubes
Human Mouse Lynx Wolf Urine collected from snow
Available Sizes and Formats
Urine Collection and Preservation Tubes (50 cc) – Urine inputs from 5 – 45 mL
Storage Conditions and Product Stability All tubes should be kept tightly sealed and stored at room temperature (15 – 25°C) for up to 2 years without any reduction in performance.
Extract total RNA (including microRNA) from FFPE samples
No phenol extraction step
Includes DNase for optional on-column DNA removal
Isolated RNA is of the highest quality and integrity
Isolate a diversity of RNA species
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
Norgen’s FFPE RNA Purification Kits provide a rapid method for the isolation and purification of total RNA (including microRNA) from formalin-fixed paraffin-embedded (FFPE) tissue samples in as little as 1 hour. Using formalin to fix tissues leads to crosslinking of the RNA and proteins, and the process of embedding the tissue samples can also lead to fragmentation of the RNA over time. Norgen’s FFPE RNA Purification Kits provide conditions that allow for the partial reversing of the formalin modifications, resulting in a high quality and yield of RNA. These kits are able to purify all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA), depending on the age of the FFPE tissue as fragmentation of the RNA is known to occur over time. The RNA is preferentially purified from other cellular components without the use of phenol or chloroform.
FFPE RNA Purification Kit (Spin Column)
Maximum loading volume of 650 μL per column, and a maximum binding capacity of 50 μg per column.
Purification is based on 96-well column chromatography using Norgen’s proprietary resin as the separation matrix. Purification can be performed using either a vacuum manifold or centrifugation. Maximum loading volume of 400 μL per well, and a maximum binding capacity of 50 μg per well.
5 slices of < 20 µm thick paraffin slices 25 mg of unsectioned block
Average Yield
Variable due to age of paraffin blocks ~2-3 µg of Total RNA per 1 mg of fresh FFPE hamster kidney
* Time required for purification varies by length of Proteinase K incubation and formalin crosslink-reversal
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. The DNAse I and Proteinase K should be stored at -20°C upon arrival. This kit is stable for 1 year from the date of shipment.
