SKU: 700004339

58 assays (manual) / 580 assays (microplate) / 700 assays (auto-analyser) 

The D-Sorbitol/Xylitol test kit for the determination Of D-Sorbitol And Xylitol In Foodstuffs, such as bakery goods, diabetic foods, chocolate, fruit, sweets and more.

Sorbitol is non-cariogenic and finds many dietetic applications, but can cause gastrointestinal problems in adults if large quantities are consumed (10-50 g per day). It has been safely used in processed foods for almost half a century and finds applications in the cosmetics and pharmaceuticals industries.

Note for Content: The number of manual tests per kit can be doubled if all volumes are halved.  This can be readily accommodated using the MegaQuant^TM  Wave Spectrophotometer (D-MQWAVE).

The D-Sorbitol/Xylitol test kit for the determination Of D-Sorbitol And Xylitol In Foodstuffs, such as bakery goods, diabetic foods, chocolate, fruit, sweets and more.

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.

FBS Exosome Depletion Kit (Slurry Format)

For FBS volumes ranging from 140 mL to 280 mL.

FBS Exosome Depletion Kit (Column Format)

For FBS volumes ranging from 120 mL to 240 mL.

Isothermal nucleic acid Principle Summary

The kit is based on room and constant temperature nucleic acid rapid amplification technology, its principle is that at room and constant temperature, the recombinase and primer form a protein/single-stranded nucleotide complex Rec/ssDNA, and invade the double-stranded DNA template with the help of auxiliary proteins and single-stranded binding protein SSB; then form a D-loop region at the invasion point and start to scan the DNA duplex, after finding the target region complementary to the primer and disintegration of the complex Rec/ssDNA, the polymerase also binds to the 3′ end of the primer to start the chain extension. The kit relies on the role of NFO enzyme and adds the designed specific molecular probes according to the template, and get the result by colloidal gold technology (sandwich method).
