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
Megazyme’s catalase assay kit provides a simple colourimetric method for the measurement of catalase activity. The method is delivered in a fast and reliable format and may be used to detect catalase activity in various samples, including food, biological and bacterial samples. The calculation method included allows for significant variation in the concentration of the H2O2 substrate solution that is employed in the assay which translates into a reduction in the ‘hands on’ time required by the analyst in comparison to other commercial kits.
See our complete list of assay kits for the measurement enzyme activity.

Isothermal nucleic acid Principle Summary
This kit is based on a rapid nucleic acid amplification technology at room temperature and constant temperature: at room temperature and constant temperature (generally 39 ºC~42 ºC), reverse transcriptase uses specific primers and template RNA to synthesize cDNA strands, and binds the auxiliary protein and single strand With the help of the protein, the recombinase and the primer form a complex; perform a homology search and bind the target homology domain, at this time a D-loop region is formed at the homology position and strand exchange begins; accompanied by the recombinase from the complex Upon dissociation, the polymerase also binds to the 3′ end of the primer, initiating chain extension. Relying on the action of nfo enzyme, adding specific molecular probes designed according to the template, and using colloidal gold technology (sandwich method) can detect the final result.
