TCO-PEG2-DBCO is a short PEG linker featuring a trans-cyclooctene and a DBCO group. DBCO is a click chemistry handle which easily reacts with azides, while the TCO function readily reacts with tetrazine-containing compounds.

Giardiasis is a disease of the small bowel caused by the protozoan parasite Giardia intestinalis (syn.duodenalis or lamblia). Giardia is one of the most common intestinal parasites in the world, and occurs at very high prevalence rates in places with poor water sanitation. Individuals become infected through ingesting or coming into contact with contaminated water, food or soil. It can also be spread through the faecal-oral route due to poor hygiene practices, which makes it common in day-care centers. G. intestinalis lives inside the intestines of infected humans or other animals including cats, dogs, birds, cows, beaver and deer. Symptoms of infection include diarrhea, malaise, excessive gas, bloating, nausea, diminished interest in food, possible vomiting and weight loss.
There are 2 kits available for the detection of Giardia intestinalis:
Giardia intestinalis TaqMan RT-PCR Kit, 100 reactions
Giardia intestinalis TaqMan RT-PCR Probe/Primer Set and Controls, 100 reactions

Storage Conditions and Product Stability
All kit components can be stored for 1 year after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.

Norgen’s Plasma/Serum Exosome and RNA Isolation Kits constitute all-in-one systems for the purification of exosomes and the sequential isolation of exosomal RNA from different plasma/serum sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. These kits are 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. 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.
Norgen’s Plasma/Serum Exosome and RNA Isolation Mini Kit
For sample volumes ranging from 50 µL to 1 mL. This kit allows the user to elute into a flexible elution volume ranging from 50 µL to 100 µL.
Norgen’s Plasma/Serum Exosome and RNA Isolation Midi Kit
For sample volumes ranging from 1 mL to 4 mL. This kit allows the user to elute into a flexible elution volume ranging from 50 µL to 100 µL.
Norgen’s Plasma/Serum Exosome and RNA Isolation Maxi Kit
For sample volumes ranging from 4 mL to 10 mL. This kit allows the user to elute into a flexible elution volume ranging from 50 µL to 100 µL.

Storage Conditions and Product Stability
All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.
Important Note
This kit is suitable for the purification of exosomes from fresh or frozen serum or plasma prepared from blood collected on either EDTA or Citrate. Plasma samples prepared from blood collected on heparin should not be used as heparin can significantly interfere with many downstream applications such as RT-PCR.
