SD-25/SD-25C Vacuum Centrifugal Concentrator

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.

Exemplary tetraplex PCR assay

Detection of three specific pathogen targets and an internal control. Total input DNA per reaction was 10^6 (red), 10^5 (yellow), 10^4 (blue), 10^3 (green), 10^2 (purple), 10 (light blue) and 0 copies (grey) and 8000 copies/reaction for the internal control (shown in the CY5 plot).

5x Multiplex – robust PCR perforemance for a wide range of qPCR application

PlexTaq 5x qPCR Multiplex Master Mix contains all components necessary for rapid, sensitive and reproducible quantification of DNA and cDNA. An engineered DNA polymerase and an optimized buffer including ultrapure dNTPs are key components of the ready to use mix. A hot-start formulation of the included DNA polymerase prevents aptamer prevents false amplification and provides a fast start function. 

PlexTaq®´s formulation allows to use it also for direct PCRs from crude samples.
