Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.
The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.
Details of the target and priming specificity are included in the individual handbooks above.
Packaged, optimised and ready to use. Expect Better Data.

Propargyl-PEG13-bromide is a heterobifunctional reagent that can participate in copper catalyzed azide-alkyne Click Chemistry to form a stable triazole linkage. The bromide (Br) can be used in nucleophilic substitution reactions. The PEG units increase water-solubility of the molecule in in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Intended Use
For the enumeration of enterococci in water and other liquids by the membrane filtration technique.
Principle and Interpretation
The growth of the entire accompanying Gram-negative microbial flora is inhibited by sodium azide. Enterococci reduce 2,3,5-Triphenyl tetrazolium chloride (TTC) to give a red formazan inside the bacterial cell, their colonies are thus red. Nitrogen, minerals, and amino acids are provided by the tryptose whilst yeast extract supplies vitamins. Glucose acts as the carbon source, dipotassium phosphate buffers the medium, and agar-agar is the solidifying agent.
Formulation
