Overview
Quantified standard to be used as a positive control or PCR quantification standard
Vigorously quantified using multiple methods
Salmonella enterica has emerged as a significant foodborne pathogen that poses 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.
Norgen’s Salmonella enterica 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 Salmonella enterica.
Upon receipt, store Norgen’s Salmonella enterica Quantified Bacterial DNA Standard at -20oC or lower. Avoid multiple freeze-thaw cycles. If needed, prepare smaller working aliquots and store at -20oC or lower.
R-Phycoerthyrin (R-RPE) Streptavidin Conjugate designed for Lateral Flow
Our Streptavidin R-Phycoerythrin conjugates are manufactured from a red algae and the first of its kind protein based fluorescent particles specifically desinged for lateral flow applications. R-RPE is a highly absorptive fluorescent molecule that has excellent detectability. It is the fluorochrome of choice when the brightest signal is needed and is therefore used most often when high sensitivity is essential for detectability and/or accuracy.
Consistent lot-to-lot performance resulting from continuous culture of source organisms and high purity. – Very high water solubility – Homogeneous structure with defined molecular weights – Total control on growth conditions and nutrition, which avoids contamination from extraneous organisms and waste found in the open ocean. Proteins are harvested at the optimal stage of the growth cycle to assure uniform product characteristics. The pigment is extracted and stabilized within minutes of harvest, virtually eliminating risks from the action of proteases.
