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:
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.
N-(alcohol-PEG2)-N-bis(PEG2-propargyl) has a hydroxyl group and two propargyl groups. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The propargyl groups can participate in copper catalyzed azide-alkyne Click Chemistry.
