Mal-amido-PEG5-alkyne is a PEG linker containing a maleimide group and an alkyne. The hydrophilic PEG spacer increases solubility in aqueous media. The alkyne group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Giardia intestinalis TaqMan RT-PCR Detection Kit Dx

Overview

  • Detection kits for Giardia intestinalis
  • CE-IVDD marked in accordance with the European Commission Directive 98/79/EC.
  • Research version available
  • Available in Taqman format for analysis

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.

Storage Conditions

The Giardia intestinalis TaqMan RT-PCR Kit Dx is shipped on dry ice. The components of the kit should be frozen upon arrival. If one or more of the components is not frozen when the kit is received, or if any of the components have been compromised during shipment, please contact Norgen Biotek for assistance. All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 3 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.

Staphylococcus aureus Quantified Bacterial DNA Standard

Overview

  • Quantified standard to be used as a positive control or PCR quantification standard
  • Vigorously quantified using multiple methods

Mastitis is the single most costly disease of dairy cattle resulting in the reduction of milk yield and quality. The inflammation of the utter is mainly caused by bacteria, and Staphylococcus aureus (S. aureus) is often considered the most common cause of contagious mastitis in dairy herds. S. aureus infection is estimated to be present in up to 90% of dairy farms and is responsible for 35% of the economic loss in the dairy industry. S. aureus is a facultatively anaerobic, Gram positive bacterium. The majority of S. aureus strains are catalase-positive and coagulase-positive, which forms the basis of traditional identification methodology.

Staphylococcus aureus Quantified Bacterial DNA Standard is prepared from cultured bacteria using Norgen’s sample preparation technology. The purified DNA is quantified vigorously using multiple methods including spectrophotometry, gel densitometry and real-time PCR. It is intended to be used as a positive control or PCR quantification standard for Staphylococcus aureus.
