Overview

• Detection kits for Cryptococcus neoformans
• Available in TaqMan format for analysis

Cryptococcus neoformans is an encapsulated yeast. Infection with C. neoformans is known as cryptococcosis and is the cause of the most common life-threatening meningitis in patients with weakened immune systems, particularly in advanced HIV/AIDS. C. neoformans is commonly found in soil throughout the world. Human infection of C. neoformans occurs via inhalation of aerosolized spores. From the lungs, C. neoformans is spread hematogenously to the Central Nervous System (CNS), resulting in meningoencephalitis. Although the availability of antiretroviral therapy in the developed world has reduced the incidents of cryptococcosis, it is still a major problem in developing countries and is one of the leading causes of death in patients with HIV/AIDS. In fact, one of the major challenges in treating cryptococcosis is that many patients with cryptococcal CNS disease are asymptomatic in terms of cryptococcal pneumonia, making it difficult for early detection.

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. 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.

Overview

• Convenient optimized on-column DNase treatment using Norgen’s RNA Purification Kits
• Also includes protocol for digestion in-solution followed by RNA Clean-Up
• Guaranteed RNase-Free
• Includes Enzyme Incubation Buffer
• Cat. 25710 contains one vial of 1,600 units and Cat. 25720 contains 4 vials (1,600 units/vial)

Norgen’s RNA purification kits isolate total RNA with minimal amounts of genomic DNA contamination. However, for some sensitive downstream applications, it may be desirable to remove all traces of residual DNA. Norgen’s RNase-free DNAse I Kit, with Enzyme Incubation Buffer, can be used for optional on-column DNase digestion with any of Norgen’s RNA purification kits. Alternatively, after isolating total RNA using one of Norgen’s RNA purification kits, the RNA elution can be treated with this DNase I. The RNA can then be purified from the DNase using Norgen’s RNA Clean-Up and Concentration Kit (Cat# 23600), and the RNA can then be used in downstream applications.

Details

Each RNase-Free DNase I Kit is supplied complete with sufficient enzyme and enzyme incubation buffer for 50 or 200 reactions.

Storage Conditions
The DNase I provided is in lyophilized form. It is stable for at least 3 months if stored at room temperature. However, it is recommended to store the DNase I vial at 2 – 8ºC (or below) upon receipt to maintain stability beyond 3 months. Buffer DR and Enzyme Incubation Buffer can be stored at room temperature. After reconstitution with Buffer DR (see product manual), the DNase I should be stored at -20ºC. All reagents should remain stable for at least 1 year in their unopened containers at the appropriate storage temperature.

The D-Glucose Assay Kit (Megaplex Red) provides a simple robust method for the measurement of D-glucose. This kit utilises a highly sensitive Megaplex Red probe which when coupled to horseradish peroxidase (HRP) and glucose oxidase (GOX) enzymatic reactions, allows for the measurement of D-glucose in a sample. Upon oxidation of the probe by HRP, a coloured product (resorufin) is formed that can be measured in fluorescence mode using excitation between 530-560 nm and emission at ~ 590 nm* or colourimetrically at 570 nm.

*The excitation and emission maxima of Megaplex Red are 570 nm and 585 nm respectively.
