The PM2600 ExcelBand™ 3-color High Range Protein Marker is a ready-to-use three-color protein standard with 12 pre-stained proteins covering a wide range of molecular weights from 10 to 245 kDa in Tris-Glycine Buffer (9 to 235 kDa in Bis-Tris (MOPS) buffer and 10 to 235 kDa in Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa and 75 kDa respectively) when separated on SDS-PAGE (Tris-Glycine buffer). The PM2600 3-color High Range Protein Marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins.

Overview
Isolate high quality total RNA (including small RNA and microRNA) and all sizes of circulating and exosomal RNA, including microRNA from urine and cerebrospinal fluid (CSF) samples
Small urine and CSF input ranging from as low as 0.5 mL to 1 mL
No phenol extractions
Very sensitive and linear down to a few cells without the need for carrier RNA
Bind and elute all RNA irrespective of size or GC content, without bias
Rapid and convenient spin column protocol
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
Norgen’s Urine microRNA Purification Kit provides a rapid method for the isolation and purification of small RNA molecules (All sizes, including < 200 nt) from urine samples. These small RNAs include regulatory RNA molecules such as microRNA (miRNA) as well as tRNA and 5S rRNA. Small RNA molecules are often studied due to their ability to regulate gene expression. Typically miRNAs are 20-25 nucleotides long and regulate gene expression by binding to mRNA molecules and affecting their stability or translation. Several recent studies have shown that miRNA regulates cell growth and apoptosis. Furthermore, clinical and experimental analyses suggested that miRNAs may function as a novel class of oncogenes or tumor suppressor genes. MicroRNA expression profiles of different tumor types, relative to their normal tissues, have recently been shown to provide phenotypic signatures for particular cancer types. Unique patterns of aberrant miRNA expression may serve as molecular biomarkers for tumor diagnosis, prognosis of disease-specific outcomes, and prediction of therapeutic responses.
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment.
Suitable for self-collection of saliva samples supervised by a trained individual in the collection procedure by watching the training video and reading over the collection instructions.
Norgen’s Saliva RNA Collection and Preservation Devices Dx are designed for 1) safe and non-invasive supervised self-collection of saliva specimens and 2) preservation of RNA in saliva specimens at ambient temperature. Each of the 50 Saliva RNA Collection and Preservation Devices Dx consists of 3 components: (1) Saliva Collection Funnel and Collection Tube, (2) Collection Tube Cap, and (3) Norgen’s Saliva RNA Preservative contained within a sealed squeezable ampoule. Saliva collection is performed through supervised self-collection. Saliva samples are collected by spitting inside the Collection Funnel which has been assembled with the Collection Tube. After collecting the required volume of saliva the Collection Funnel is removed and the contents of the Preservative Ampoule are then added and mixed with the collected saliva. The Saliva Collection Tube is subsequently sent to the laboratory for RNA isolation and analysis. RNA can be isolated from the preserved saliva samples using Norgen’s Saliva/Swab RNA Purification Kits Dx (Cat# Dx69100, Dx69300). Each of Norgen’s Collection Tubes is labeled with a unique serial number that can be used for secure and anonymous tracking of the sample. The saliva RNA in preserved samples is stable for up to 2 months at room temperature. This kit is ideal for collecting and preserving RNA samples for in vitro diagnostic use for medical purposes. This kit can be used to collect and preserve viral RNA, including SARs-CoV-2 RNA for detection of COVID-19.
Norgen’s Saliva RNA Collection and Preservation Devices Dx do not provide a diagnostic result. It is the sole responsibility of the user to use and validate these devices in conjunction with a downstream in vitro diagnostic assay.
Saliva RNA Preservative
Norgen’s Saliva RNA Preservative is an aqueous storage buffer designed for rapid cellular lysis and subsequent preservation of RNA from fresh saliva specimens. The buffer 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 buffer allow samples to be stored for up to 2 months at room temperature. The Saliva RNA Preservative also inactivates all bacteria, yeast and viruses present in the saliva sample.
Nucleic Acid Isolation from Preservative
Saliva RNA can be isolated from the preserved saliva samples using Norgen’s Saliva/Swab RNA Purification Kits Dx (Cat# Dx69100, Dx69300). To minimize irregularities in diagnostic results, suitable controls for downstream applications should be used.
The Collection Device should be kept tightly sealed and stored at room temperature for up to 2 years without any reduction in kit performance (The collection due date is written on the device label).
Once collected, saliva RNA is stable for up to 2 months when kept tightly sealed and stored at room temperature.
The Collection Tube, the Collection Funnel and the Device Container of each individual Saliva RNA Collection and Preservation Device are recyclable.

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.
