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.

RNA Seq Library Prep Kit (illumina and MGI Platforms)
Product Info
Document
Product Info
The RNA Seq Library Prep Kit was developed for construction of high quality NGS libraries for next generation sequencing (illumina and MGI Platforms). RNA Sequencing is a very powerful tool to analyze transcriptome such as gene expression and transcription regulation, splicing characterization, mutation and variation detection etc. The kit needs purified RNA (example: rRNA depleted RNA or polyA mRNA) as input for library construction. Library multiplexing is possible with different types of indexes.
RNA Seq Library Prep Kit Workflow
Three index types are available for the illumina platform kits:
Non-index (illumina Cat.# 30055): Libraries do not have index.
Index (illumina Cat.# 30056): A unique barcode sequence with 6 bases has been included in each of the index primers. RNA Sequencing library multiplexing is possible with up to 48 samples. Index information can be downloaded here.
Unique dual index (illumina Cat.# 30057): RNA Sequencing library multiplexing up to 96 samples is possible with the unique dual indexes. We have developed a 4-Base Difference Index System. The system can generate indexes with at least 4 bases different from others in the 8-base indexing region. the unique dual indexing primers identify sequencing errors such as index hopping, mis-assignment, and de-multiplexing errors. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34112).

Norgen’s Cell Culture Media Exosome Purification and RNA Isolation Kits constitute an all-in-one system for the purification of exosomes and the subsequent isolation of exosomal RNA from different cell culture media sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The kit is designed to isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias. These kits provide a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kits allow the user to elute into a flexible elution volume ranging from 50 µL to 100 µL. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. The purified RNA can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.
