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.

Norgen’s Total RNA Purification Kits Dx provide rapid methods for the isolation and purification of total RNA from tissue samples, blood, plasma, serum, saliva, bacteria, yeast, fungi and viruses for subsequent in vitro diagnostic use. Extract high quality and purity RNA with excellent RIN values and A260/A280 suitable for downstream applications including qRT-PCR, RT-PCR, microarrays, NGS and more.
Total RNA Purification Kit Dx (Spin Column)
This kit is designed to be used with any downstream application employing enzymatic amplification or other enzymatic modifications of RNA followed by signal detection or amplification. Any diagnostic results generated using the RNA isolated with Norgen’s Total RNA Purification Kit Dx in conjunction with an in vitro diagnostic assay should be interpreted with regard to other clinical or laboratory findings.
Total RNA Purification 96-Well Kits Dx (High Throughput and High Throughput Deep Well)
Thess 96-well kits provide a rapid method for the high-throughput isolation and purification of total RNA in 30 minutes using vacuum manifold, plate centrifuge, or liquid handlers with vacuum capabilities. Total RNA can be isolated from a broad range of sample sources including cultured cells, tissues, blood, serum, plasma, bacteria, yeast, fungi, and viruses.
Intended Use
To minimize irregularities in diagnostic results, suitable controls for downstream applications should be used. Norgen’s Total RNA Purification Kits Dx are intended for use by professional users such as technicians, physicians and biologists experienced and trained in molecular biological techniques. Norgen’s Total RNA Purification Kits Dx do not provide a diagnostic result. It is the sole responsibility of the user to use and validate the kit in conjunction with a downstream in vitro diagnostic assay.
