N-Boc-N-bis(PEG4-Propargyl) is a bifunctional PEG compound containing two terminal alkynes that are combined together at a Boc-protected secondary amine. Terminal alkynes are most commonly used in copper click chemistry with azides to form stable triazoles with the target molecule. The secondary amine may be deprotected under acidic conditions to allow for alkylation at that position, increasing the molecule’s structural complexity. The use of a central amine also allows for hydrogen bonding, further increasing this compound’s water solubility.

Novel method
The β-Glucan Assay Kit (Yeast and Mushroom) is suitable for the indirect measurement of 1,3:1,6-β-glucan in yeast and mushroom preparations containing starch, glycogen, sucrose and trehalose.
We are happy to announce a new and improved procedure!
Trehalase enzyme has now been added to the β-Glucan Assay Kit (Yeast and Mushroom), further increasing the accuracy of β-glucan measurement for certain samples. The addition of trehalase removes instances of overestimation of β-glucan content in samples containing trehalose. Please refer to the assay protocol and the FAQ here for more information.
This product replaces the Enzymatic Yeast β-Glucan Assay Kit (K-EBHLG) as the method of measurement for β-glucan measurement in yeast samples. See here for more information.
