DBCO-PEG23-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydrophilic PEG spacer increases the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Product Info
Description
The SMOChem™ Deoxynucleotide (dNTP) Mix is an aqueous solution that contains an equimolar solution of ultrapure dATP, dCTP, dGTP and dTTP, each at a concentration of 10 mM at pH 8.5. The dNTP Mix is designed for many different molecular biology applications that involved in DNA synthesis or labeling, such as PCR, real-time PCR, DNA sequencing, reverse transcription, primer extension, and etc. The dNTP Mix is free of exo-deoxyribonuclease and endo-deoxyribonuclease as well as ribonuclease activity. The dNTP Mix offers the possibility to reduce the number of pipetting steps and the risk of reaction set up errors.
Features
Ideal for PCR amplification and cDNA synthesis
Premixed solution
Nuclease and ribonuclease free
Applications
PCR amplification of DNA fragments
DNA fill-in reaction
DNA sequencing
Reverse transcription
One-step RT-PCR
Storage
-20°C for 36 months

Listeria monocytogenes have emerged as significant foodborne pathogens that pose a serious public health problem. As the causative agent of Listeriosis, L. monocytogenes has the highest rate of fatality rate among all foodborne pathogens. L. monocytogenes is a facultatively intracellular, Gram-positive bacterium that could survive high and low temperatures, low pH. It is a rare causative agent of mastitis in cow. However, due to its ability to resist various food processing technologies as well as to grow at low temperature, L. monocytogenes is know to be associated with both raw and pasteurized milk, as well as dairy products such as cheese. As little as 1000 organisms may cause the disease with pregnant, new-born, and immunocompromised individuals the most susceptible.
The Listeria monocytogenes 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.
