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.

Gel images of different ranges of library size selection. Sheared human genomic DNA was used as input.

.

Library size selection is an enrichment of a specific range of library sizes for NGS library preparations. The NGS library preparation is related to the quality of the sequencing data. Precise NGS library size selection can increase sequencing efficiency, improve data quality, and reduce costs.

There are two types of sequencing technologies: short-read sequencing and long-read sequencing. Short-read sequencing uses DNA libraries that contain small insert DNA fragments of similar sizes, usually several hundred base pairs. The sequencing efficiency can be improved if the DNA size selection is in the right range. Cat.# 20104S and 20104L are the best kits for NGS library size selection of illumina paired-end 100 (PE100) sequencing with 100-200 bp library inserts; Cat.# 20105S and 20105L are the best kits for NGS library size selection of illumina paired-end 150 (PE150) sequencing with 150-300 bp library inserts; and Cat.# 20106S and 20106L are the best kits for NGS library size selection of illumina paired-end 300 (PE300) sequencing with 300-600 bp library inserts.

Long-read sequencing uses a large DNA fragment as input and makes very long reads. Usually, library size selection is preferred to remove smaller fragments. Cat.# 20110S and 20110L are the best kits for long-read sequencing size selection with DNA sizes >5 kb, and Cat.# 20111S and 20111L are the best kits for long-read sequencing size selection with DNA sizes >10 kb.

The magnetic beads, or SPRI (Solid Phase Reversible Immobilization) beads, is well used for the purification of DNA due to their reversible DNA binding. The NGS library can be size-selected by the magnetic beads or SPRI beads. The properties of the magnetic beads can be changed for a specific range of DNA binding. The contaminants and other unwanted components in the libraries can also be removed during size selection.

Specific ranges of NGS libraries can be selected using magnetic beads with different buffer compositions. The first DNA-beads binding step, also called the right-side clean-up, removes large NGS library fragments. The large NGS library fragments that bind to the beads are discarded with the beads pellet. The desired NGS library fragments in the supernatant are transferred to a new well, and new beads are added to the supernatant for the second beads-DNA binding, also called the left-side clean-up. After the rinsing step, the NGS library fragments with the dual selection are eluted in water or an appropriate buffer. The magnetic beads method has great advantages over time-consuming column purification and tedious gel-based purification.

NGS library size selection with dual clean-ups.

.

Library size selection for long-read sequencing only requires a single clean-up. In this case, only the large library fragments are bound to the beads, while other small library fragments are discarded with the supernatant. The selected larger library fragments are eluted in water or an appropriate buffer after the rinsing step.

NGS library size selection with single clean-up for >5 kb and >10 kb libraries.
