NH-bis(PEG2-propargyl) is a multi-branched linker with two terminal propargyl groups and an amino group. The propargyl groups reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry to yield a stable triazole linkage. The amino group is reactive with carboxylic acids, activated NHS esters, and carbonyls. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.

E. coli O157:H7 is a rod-shaped, gram negative bacterium. It is an enterohemorrhagic strain of the common E. coli bacterium and infection by the O157:H7 strain is commonly associated with hemorrhagic colitis. E. coli O157:H7 is recognized by its somatic (cell wall) antigen (O157) and its flagella antigen (H7). In addition, E. coli O157:H7 is known to produce Shiga-like toxins, which cause severe symptoms. While most patients can recover from the infection, up to 15% of the patients may develop hemolytic uremic syndrome, a type of kidney failure that could be fatal. Infection of E. coli O157:H7 usually results from consumption of poorly prepared food including undercooked meat (particularly ground beef), untreated water or raw unpasteurized milk.
Norgen’s E. coli O157:H7 Quantified Bacterial DNA Standards are cloned fragments of the two Shiga-like toxin regions purified using Norgen’s sample preparation technology. They include partial sequences of STX-1 subunit A gene and STX-2 subunit A gene. Please refer to Appendix A for sequence information. The purified DNA is quantified vigorously using multiple methods including spectrophotometry, gel densitometry and real-time PCR. It is intended to be used as positive controls or PCR quantification standards for E. coli O157:H7. This product is compatible with Norgen Biotek’s E. coli O157:H7 Taqman PCR Detection Kit (Cat. TM41350) and E. coli O157:H7 Taqman PCR Detection Probe/Primer and Control Set (Cat. TM41310).

Storage Conditions
Upon receipt, store Norgen’s E. coli O157:H7 Quantified Bacterial DNA Standards at -20°C or lower. Avoid multiple freeze-thaw cycles. If needed, prepare smaller working aliquots and store at -20°C or lower.
Real-time fluorescent DNA amplification in a flexible liquid format. Recommended for users who want to combine RPA with the use of TwistDx’s proprietary fluorescent TwistAmp® exo Probes. In addition to the basic components, a powerful nuclease (Exonuclease III) is provided which will process TwistAmp® exo Probes during the amplification reaction itself and generate a real-time readout. The user need only supply primers, probe, dNTPs and template.See manual for more information. Click to order oligonucleotides.
Perfect for: Real-time fluorescent DNA detection, facilitating use of different RPA reaction volumes, or variation of component ratios.
