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 MegaQuant^TM  Wave Spectrophotometer (D-MQWAVE).

Mal-amido-PEG5-alkyne is a PEG linker containing a maleimide group and an alkyne. The hydrophilic PEG spacer increases solubility in aqueous media. The alkyne group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Reagent grade, for research purpose.
