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.

Introduction

The HiPure Mini system provides a fast, simple, and cost-effective plasmid DNA miniprep method for routine molecular biology laboratory applications. HiPure Plasmid Mini Kits use silica membrane technology to eliminate the cumbersome steps associated with loose resins or slurries. Plasmid DNA purified with Mini Kits is immediately ready for use. Phenol extraction and ethanol precipitation are not required, and high quality plasmid DNA is eluted in a small volume of tris buffer or water.

Compared to other domestic products, Magen was the first to solve the stability problem of the column. Many other brands have unstable extraction concentrations, and the longer the time, the more unstable the column becomes. However, in our test of Magen kit, the quality and yield of plasmid extraction still remain stable after 5 years’ storage. For different customers, our kits can be customized. For example, Classic type is suitable for customers with low copy or unclear plasmid types. The rapid type is suitable for customers with high copy plasmids. Compared to many other brands, the plasmid DNA extracted by Magen has a longer preservation time and more thoroughly RNA removal.

Principle

The HiPure Plasmid procedure is based on alkaline lysis of bacterial cells followed by adsorption of DNA onto silica in the presence of high salt. The unique silica membrane used in the kit completely replaces glass or silica slurries for plasmid DNA minipreps. The procedure consists of 3 basic steps: Preparation and clearing of a bacterial lysate by alkaline method，then transfer the supernatant to column to bind DNA. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).

Advantages

• High purity – purified plasmid can be directly used in sequencing, enzyme digestion and PCR, etc.
• Fast – it takes only 1 minute to obtain supernatant by optimized solution (10 minutes for other brands)
• High yield – up to 35µg plasmid can be binded in one column
