endo-BCN-PEG2-PFP ester is a click chemistry active ester. The PFP esters have similar applications as the NHS esters, but are more stable in aqueous solution. They can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The BCN group can react with azide-tagged biomolecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The Fructan Assay Kit is suitable for the specific measurement of fructan in plant extracts, animal feed and food products containing starch, sucrose and other sugars. It is used in three validated methods for the determination of fructan: AOAC method 999.03 (foods), AOAC method 2018.07 (Animal Feed) and AOAC method 2016.14 (infant formula and adult nutritionals).
New, improved procedure.
In the most recent development, a recombinant endo-levanase has been incorporated into the fructanase mixture, extending the use of the method to the measurement of levan-type fructans as are present in grasses such as timothy, cocksfoot, ryegrass and red fescue.
The method described in this booklet employs ultra-pure, recombinant enzymes and specifically measures fructans including inulin-type fructans from chicory, dahlia, jerusalem artichoke; highly branched fructans from onion and wheat stems and leaves; and levan-type fructans from pasture grasses such as timothy grass. The enzymes employed are completely devoid of contaminating enzymes active on β-glucan or gluco-oligosaccharides.

Description
The IdPath™ COVID-19 Real-Time RT-PCR Kit is a real-time RT-PCR test intended for the detection of SARS-CoV-2 virus RNA which might be extracted from the respiratory tract specimens. The Kit provides reagents for multiplex real-time RT-PCR to detect SARS-CoV-2 by one-step reaction, specifically targeting the E (Envelope), RdRP (RNA-dependent RNA polymerase) and N (Nucleocapsid protein) gene for SARS-CoV-2 virus.
The Kit contains the RT enzyme mix and qPCR master mix for reverse transcription and real-time PCR of virus RNA. The COVID-19 Control (positive control) and ddWater (negative control) are used as indicators to avoid false negative/positive results across all experimental procedures. The Primers/probes Mix contains multiplex primers and TaqMan probes specific to the N, E/RdRP genes of SARS-CoV-2 and RNase P gene of human, detected by FAM, VIC and ROX channels, respectively.
