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.

Instructions:
To reconstitute the lyophilized RNA ladder, add 250 µL of 1x loading buffer to each 25 loads vial and vortex gently.
Heat at 80°C for 10 minutes. Incubate on ice for 1 min. Load 10 µL on a 1.5-2% gel. For optimal results, use Norgen 2x loading buffer with each RNA sample. There is no need for staining and destaining denaturing gels since Norgen’s loading buffer contains ethidium bromide.
Storage:
Store at -20°C.
Norgen’s Milk DNA Preservation and Isolation Kit is an all-in-one solution designed for 1) preservation of DNA in milk samples at ambient temperature; and 2) isolation of high quality DNA within a laboratory setting. The kit is provided with a Preservation Solution that allows for either immediate processing of milk samples, or allows for the storage of the milk samples for up to 1 month at room temperature prior to DNA isolation. Genomic DNA extracted from somatic cells and bacteria found in milk can be used in various applications. The isolated DNA can be used for the detection of biomarkers to diagnose a disease, follow the diseases progress or monitor the effects of a particular treatment. Milk DNA can also be used to diagnose particular types of infections. Milk DNA purified using Norgen’s kit is of the highest quality, and is compatible with a number of downstream applications including PCR, Southern Blot analysis, sequencing and microarray analysis.
Milk DNA Preservative
Norgen’s Milk DNA Preservation Solution is an aqueous storage buffer designed for rapid cellular lysis and subsequent preservation of DNA from fresh specimens. 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 preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperature. The components of the preservative allow samples to be stored for 1 month without any detectable DNA degradation.

Storage Conditions and Product Stability
The Proteinase K should be stored at -20°C upon arrival and after reconstitution. All other solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment.
Storage in Preservation Buffer
1) Storage at -20°C is recommended for archival samples and will provide optimal preservation. The preservation buffer will freeze at -20°C. Samples can be stored indefinitely at -70°C.
2) Samples can be stored at room temperature (25°C) for up to 1 month without significant loss of DNA quality.
3) DNA has also been successfully isolated from samples stored at 37°C 1 for one week.
