Ready to Use CdSe/ZnS Qdots Nanoparticle Streptavidin Conjugate for Lateral Flow
Our Streptavidin CdSe/ZnS Quantum Dots (QDs)conjugate is manufactured using special conjugation technology and functonally tested by lateral flow. We have coated our high quality nanoparticles with a proprietary surface coat that covalently binds the biotin forming ultra stable conjugates. The resulting Streptavidin CdSe/ZnS QDs can irreversibly bind biotin.
fluorescent broad range UV light excitation range of 100nm to 400nm, 655nm emission

Norgen’s Total Nucleic Acid Preservation Tubes Dx are designed for ambient preservation and transport of total nucleic acids (DNA and RNA) from samples collected using a swab. The Total Nucleic Acid Preservation Tubes contain Norgen’s Total Nucleic Acid Preservative in a liquid format. The user simply collects the specimen using a sterile nylon flocked swab (not provided), and then transfers the swab into the Total Nucleic Acid Preservative. The Preservative prevents the growth of Gram-negative and Gram- positive bacteria and fungi, and also inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely. In addition, the Total Nucleic Acid Preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperatures. The components of the preservative allow DNA samples to be stored at room temperature for over 4 months and RNA samples to be stored at room temperature for over 2 months. This kit is ideal for collecting and preserving nasal and oral swab samples for in vitro diagnostic use for medical purposes. This kit can be used to preserve viral RNA, including SARs-CoV-2 RNA for detection of COVID-19.
Norgen’s Total Nucleic Acid Preservation Tubes Dx are intended for use by professional users such as technicians, physicians and biologists experienced and trained in molecular biological techniques.
Norgen’s Total Nucleic Acid Preservation Tubes Dx do not provide a diagnostic result. It is the sole responsibility of the user to use and validate these devices in conjunction with a downstream in vitro diagnostic assay.
Shelf Life and HandlingThe tubes should be kept tightly sealed and stored at room temperature for up to 1 year without any reduction in performance (The collection due date is written on the device label and the kit box label).Once collected, RNA is stable for up to 2 months and DNA is stable for up to 4 months when the tubes are kept tightly sealed and stored at room temperature.
CE-IVD marked version available for in vitro diagnostic use
Available in TaqMan format for analysis
Mycobacterium tuberculosis is a pathogenic bacterial species belonging to the genus Mycobacterium, and is the causative agent of tuberculosis. Tuberculosis (TB) is a multifaceted disease and challenging public health problem in both industrialized and developing countries. According to the WHO, 8.8 million active cases of TB are diagnosed each year and of these, almost 2 million die. Once thought to be under control or even close to extinction, TB infection levels are rising and the threat is compounded by new, virulent and drug-resistant strains. Although most cases occur in the developing world (22 countries accounting for 80% of all global cases), increasing population mobility combined with facility of transmission means that no country is immune from the resurgence of TB. TB control programs are currently facing a number of constraints. Worldwide, fewer than 25% of all tuberculosis cases are detected. Of utmost concern is the absence of a timely and accurate test for the diagnosis of mycobacterial disease. Early diagnosis is crucial for the prevention of further spread of the disease.
Storage Conditions and Product Stability All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival.
