Overview

• Efficient depletion of bovine exosomes from Fetal Bovine Serum
• Deplete exosome-sized vesicles from versatile FBS volumes
• No protease treatment required
• No time-consuming ultracentrifugation
• No precipitation reagents required
• No overnight incubation required
• Exosome depletion confirmed by reduction of bovine miRNAs below detectable levels
• The depleted FBS provides the same cellular growth rates as the standard FBS
• Purification is based on Norgen’s proprietary Silicon Carbide resin matrix

Norgen’s FBS Exosome Depletion Kits provides a quick and easy protocol for the depletion of bovine exosomes from FBS prior to using it as a growth supplement in your culture medium. The FBS recovered from the depletion process is exosome-depleted and does not contain any quantifiable bovine miRNAs. Moreover, the exosome-depleted FBS will support the growth of your cells of interest similar to the non-depleted FBS. Norgen’s kits allow for the processing of different FBS volumes. The depletion is based on Norgen’s proprietary resin. These kits provide a clear advantage over other available kits in that they do not require ultracentrifugation, any special instrumentation, precipitation reagents or any protease treatments. More importantly, the depletion process is an inexpensive method for exosome depletion from FBS, as compared to the expensive current ready-to-use exosome-depleted media available on the market.

Background

Most culture medium used for the growth and propagation of cells in culture require the addition of fetal bovine serum (FBS) as a growth supplement to media. FBS is obtained from bovine (cow) serum, and therefore contains large quantities of bovine exosome vesicles. These exosomes may interfere with some types of studies, or may lead to unreliable results when studying the exosomes shed from your cells of interest in normal culture conditions. Therefore, the use of exosome-depleted FBS is highly recommended for many types of studies.

FBS Exosome Depletion Kit (Slurry Format)

For FBS volumes ranging from 140 mL to 280 mL.

FBS Exosome Depletion Kit (Column Format)

Storage Conditions and Product Stability
All buffers should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment.

Overview

• Reliable and cost-effective
• Non-invasive, user-friendly sample collection and preservation in one convenient kit
• Preserved DNA is stable for 2 years at ambient temperature
• Compatible with any commercial DNA isolation methods including Norgen’s Saliva DNA Isolation Kits (Cat. RU45400)
• Samples are non-infectious and can be handled and shipped safely
• Shipping accessories can be purchased separately
• High quality DNA is suitable for sensitive downstream applications including PCR, qPCR, sequencing, SNP analysis, microarrays, RFLP and Southern Blot Analysis

Norgen’s Saliva DNA Collection and Preservation Devices are designed for 1) simple and non-invasive saliva collection and 2) preservation of DNA in saliva samples at ambient temperature. Each of the 50 Saliva DNA Collection and Preservation Devices consists of 3 components:

• Saliva Collection Funnel and Collection Tube
• Collection Tube Cap
• Norgen’s Saliva DNA Preservative contained within a sealed squeezable ampoule

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 DNA isolation and analysis. DNA can be isolated from the preserved saliva samples using Norgen’s Saliva DNA Isolation Kit (Cat. RU45400). 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 DNA in preserved samples is stable for more than 2 years at room temperature. This kit is ideal for collecting and preserving DNA samples for epidemiological and population studies.

Saliva DNA Preservative

Norgen’s Saliva DNA Preservative is an aqueous storage buffer designed for rapid cellular lysis and subsequent preservation of DNA from fresh specimens. The buffer 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 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 more than 2 years without any detectable DNA degradation.

DNA Isolation from Preservative

Prior to saliva DNA isolation, vortex the Collection Tube containing preserved saliva for 10 seconds and incubate at 55°C for one hour. Saliva DNA can now be isolated from the preserved saliva samples using any commercially available method, including Norgen’s Saliva DNA Isolation Kit (Cat. RU45400), Norgen’s Saliva DNA Isolation 96-Well Kit (Cat. RU35200) and Norgen’s Saliva DNA Isolation Kit (Magnetic Bead System) (Cat. RU55400, RU62900). Also, Norgen’s Saliva DNA Isolation Reagent Kit (up to 4 mL) (Cat. RU35720) allows for DNA isolation from the preserved saliva samples using an alcohol precipitation method. The purified DNA is of the highest quality and can be used in a number of downstream applications including PCR, NGS and microarray analysis.
