Propargyl-PEG12-methylamine is a propargyl linker that is commonly used as a Click Chemistry reagent for copper-catalyzed reactions with azides. The methylamine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde), etc. The PEG spacer helps improve the water solubility of the molecule in aqueous media. Reagent grade, for research use only.

APN-C3-PEG4-alkyne is a heterobifunctional linker containing an APN moiety with exquisite chemoselectivity for cysteine and an alkyne group. The superior stability of APN-cysteine conjugates in aqueous media, human plasma, and living cells makes this new thiol-click reaction a promising methodology for applications in bioconjugation. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

This kit provides a single tube to screen for the presence of high-risk HPV types, HPV16, HPV18, HPV31, HPV33, HPV35, HPV39, HPV45, HPV51, HPV52, HPV56, HPV58, HPV59, HPV66 and HPV68. The multiplex test is detected in two fluorescent channels differentiating between HPV16 / HPV18 which both produce a VIC channel signal and all others which produce a signal in the FAM channel. HPV16 and HPV18 account for 70% of positive findings in clinical practice so it is helpful to know if either of these are present. All other high risk genotypes together make up the remaining 30% of clinical positives and are grouped together into the FAM channel. In this configuration, the kit gives a partial genotyping result and some additional information on which high risk strains are present.
Exceptional value for money
Rapid detection of all clinically relevant subtypes
Highly specific detection profile
High priming efficiency
Broad dynamic detection range (>6 logs)
Sensitive to < 100 copies of target
Accurate controls to confirm findings
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.
