Propargyl-PEG6-t-butyl ester is a heterobifunctional linker consisting of an alkyne group and a t-butyl protected carboxyl group. The alkyne group can participate in copper catalyzed azide-alkyne Click Chemistry to form a stable triazole linkage. The t-butyl group can be hydrolyzed under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.
