Champion™ Competent Cells
pUC19 Control Plasmid (5 μl, 10-4 μg/μl)
Champion™ Transformation Protocol Card
Shipping condition
Throughout the shipping process, the temperature is maintained under -70°C.
Storage and expiration
Champion™ Competent Cells must be stored between -70°C to -80°C. Subsequent freeze-thaw cycles will reduce transformation efficiency. If high efficiency is required for the experiment, do not use aliquots that have gone through several freeze-thaw cycles. The efficiency of Champion™ Competent Cells lasts for 1 year with proper storage.

Stool Nucleic Acid Collection and Preservation Devices Dx
Product Info
Document
Product Info
Overview
CE-IVDR marked in accordance with the European Commission Regulation (EU) No. 2017/746.
Ideal for use in in vitro workflows
No need to immediately process samples
Nucleic acid preservation at room temperature over 2 years for DNA and 7 days for RNA
Ship stool samples at room temperature safely
Compatible with most DNA/RNA isolation methods
Norgen’s Stool Nucleic Acid Collection and Preservation Devices Dx are designed for the collection and preservation of nucleic acids from fresh stool specimens. The Stool Nucleic Acid Collection and Preservation Devices Dx – 50 contains 50 individual Stool Nucleic Acid Collection and Preservation Devices Dx. Each Stool Nucleic Acid Collection and Preservation Device Dx consists of Norgen’s Stool Nucleic Acid Collection and Preservation Tube Dx containing Norgen’s Stool Preservative in a liquid format. The user simply collects stool into the tubes (fill up to the line indicated on the tube) and mixes gently until the stool is well submerged under the preservative. The Stool Nucleic Acid Collection and Preservation Tube Dx is subsequently sent to the laboratory for DNA and/or RNA isolation and analysis. The stool DNA in preserved samples is stable for more than 2 years at room temperature, and the stool RNA in preserved samples is stable for 7 days at room temperature. DNA can be isolated from the preserved stool samples using Norgen’s Stool DNA Isolation Kit Dx (Cat. Dx27600) and RNA can be isolated from the preserved stool samples using Norgen’s Stool Total RNA Purification Kit Dx (Cat. Dx49500). These tubes are ideal for collecting and preserving DNA and RNA samples for in vitro diagnostic use for medical purposes.

Salmonella enterica have emerged as significant foodborne pathogens that pose a serious public health problem. The symptoms of salmonellosis may include diarrhea, fever, vomiting, and abdominal cramps with elderly, new-born, and immunocompromised individuals the most susceptible. S. enterica is a facultatively anaerobic Gram-negative bacterium that could survive low temperatures and freezing. The majority of the 1.3 billion annual cases of Salmonella-caused human gastroenteritis result from ingestion of contaminated food products, such as raw or undercooked meat, seafood, and eggs, as well as raw or unpasteurized milk and dairy products. Salmonella infections are also contracted following consumption of fresh fruits or vegetables that have been contaminated by infected fertilizer.
Salmonella enterica TaqMan PCR Kit, 24 reactions
Ready to use format, including Master Mix for the target and PCR control to monitor for PCR inhibition and validate the quality
Specific Primer and Probe mix for the pathogen/virus/viroid of interest
Primer and Probe mix
Positive and negative control to confirm the integrity of the kit reagents
The Salmonella enterica TaqMan 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.
