3,4-Dibromo-Mal-PEG4-amide-DBCO is a PEG linker containing a dibromomaleimide group and a terminal DBCO group. The dibromomaleimide group allows for two points of attachement because both of the bromine atoms can be substituted. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. PEG linkers are hydrophilic moieties, therefore the attachment of a PEG linker to a compound increases it’s water solubility properties in aqueous media. Reagent grade, for research purpose.

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.

The D-Sorbitol/Xylitol test kit for the determination Of D-Sorbitol And Xylitol In Foodstuffs, such as bakery goods, diabetic foods, chocolate, fruit, sweets and more.
Sorbitol is non-cariogenic and finds many dietetic applications, but can cause gastrointestinal problems in adults if large quantities are consumed (10-50 g per day). It has been safely used in processed foods for almost half a century and finds applications in the cosmetics and pharmaceuticals industries.
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave Spectrophotometer (D-MQWAVE).
