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.

N-(Amino-PEG1)-N-bis(PEG2-propargyl) HCl salt is a crosslinker consisting of an amino group with two propargyl groups. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The propargyl groups can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Description

African Swine Fever Virus (ASFV) is a widespread disease which infects members of the pig family(Suidae). Anumberoftick species are believed to be the vector for the disease,as well as being transmitted by raw pork and pig excrement [1]. After firstly being identified in Kenya in 1921, ASFV became endemic in sub-Saharan Africa, with regular outbreaks being reported across Europe, Asia and South America throughout the century [2]. More recently the virus was introduced in Georgia and spread throughout the region, as well as mass outbreaks occurring in China in 2018 [3].
ASFVistheonlymemberoftheAsfaridaefamily.ItisalargeenvelopeddoublestrandedDNA virus of icosahedral morphology with an average diameter of 200nm and isolates contain genomes between 170-190Kbp encoding for up to 167 open reading frames [2]. The morphology of ASFV consist of several concentric domains. An inner core contains the nucleoid coated with a thick protein layered core shell, which is surrounded by an inner lipid envelope , all of which is encompassed by the capsid [2]. ASFV begins its replication cycle in the nucleus of infected cells before moving to the cytoplasm where the majority of the replication takes place [2]. Gene transcription is highly regulated, with distinct classes of mRNA identified to accumulate at early, intermediate and late transcripts of the virus [2]. The disease induces acute haemorrhagic disease within its hosts, causing high fevers and skin haemorrhages, with death often occurring within ten days of clinical symptoms appearing [4].
