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.

These kits are designed to clean-up and concentrate RNA (including miRNA) from TRIzol® and TRI Reagent®, enzymatic reactions, in vitro transcription, labelling reactions, etc. These are robust kits for all clean-up and concentration purposes for up to 35 µg of RNA in solution. The purified RNA is of the highest purity and integrity, and can be used in a number of downstream applications. These kits purify all sizes of RNA, from large mRNA and ribosomal RNA down to miRNA, siRNA and lncRNA.
Norgen’s RNA Clean-Up and Concentration Kit provides a rapid method for the purification, cleanup and concentration of up to 35 μg of RNA isolated using different methods including phenol/guanidine-based protocols, and from various upstream enzymatic reactions such as DNase treatment and labeling. The kit elutes RNA in 20 µL. Complete 10 purifications in 20 minutes.
Norgen’s RNA Clean-Up and Concentration 96-Well Kit provides a rapid method for the purification, cleanup and concentration of up to 50 μg of RNA isolated using different methods including phenol/guanidine-based protocols, and from various upstream enzymatic reactions such as DNase treatment and labeling. The kit elutes RNA in 75 µL. Complete 10 purifications in 30 minutes.
Norgen’s RNA Clean-Up and Concentration Micro-Elution Kit provides a rapid method for the purification, cleanup and concentration of up to 10 μg of RNA isolated using different methods including phenol/guanidine-based protocols, and from various upstream enzymatic reactions such as DNase treatment, labeling and in vitro transcription. This kit is made for eluting RNA in smaller volumes of 8 µL for all types of downstream applications, for the highest concentration of RNA sample. Complete 10 purifications in 20 minutes.
