DBCO-PEG24-NHS ester is a click chemistry PEG reagent containing NHS ester that is able to react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Water-soluble, substrate for sortase mediated labeling of proteins. Sortase catalyzes a transpeptidase reaction between a specific internal sequence of a protein and an amine group present on the N-terminus of triglycine recently has become an area of great interest. This method of labeling proteins has been denoted as “Sortagging”. Proteins conjugated to DBCO-Gly-Gly-Gly can be further modified with azide-containing molecules creating site-specific protein conjugates. Examples of creating protein conjugates using sortagging include site-specifically PEGylating proteins,1 site-specific protein-lipid conjugates,2 and constructing peptides and glycosylphosphatidylinositol chimeras.3 Sortase has also been used in peptide synthesis to cyclize peptides to create macrocyclic peptides, glycopeptides4 and protein−protein conjugates.

Novel method
The myo-Inositol Assay Kit is a reliable and accurate enzymatic UV-method for the specific measurement and analysis of myo-inositol in animal feeds, foods and various other materials.
Phytic acid content of samples with very low levels of free myo-inositol can also be determined using K-INOSL. This can be achieved by measuring the amount of myo-inositol released after de-phosphorylation of phytic acid with the enzymes phytase and alkaline phosphatase, as used with the Megazyme Phytic Acid/Total Phosphorus Assay Kit (K-PHYT).
Not suitable for the determination of myo-inositol in baby formula.
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).

Propargyl-PEG1-t-butyl ester has a propargyl group and a t-butyl protected carboxyl group. The propargyl group can participate in copper catalyzed azide-alkyne Click Chemistry to form a stable triazole linkage. The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
