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.

Advantages
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.

Overview
This kit provides a fast and simple procedure for the isolation of total proteins from tissue, bacteria, yeast or mammalian cells without the use of SDS, Triton® X-100 and other detergents. Detergents are extensively used to prepare protein samples; however, these detergents have undesirable effects on downstream analysis. These effects include extraneous peaks in mass spectrometry, artifacts with chromatography and electrophoresis, interference with microinjection into cells and interference with protein immunization.
The Detergent-Free Total Protein Isolation Kit maintains high protein recovery and yields proteins that are 100% detergent-free. Purification is based on using Norgen’s proprietary resin together with Lysis Solution, followed by protein filtration using a filter column (provided). The purified proteins can be used in a number of downstream applications including mass spectrometry, SDS-PAGE, isoelectric focusing, NMR spectroscopy and more.
Each Lysis Tube is able to process up to 50 mg of tissue, 1010 bacterial cells, 109 yeast cells or 107 mammalian cells. Preparation time for 12 samples is less than 10 minutes.

Attogene’s Organophosphate detection kit is in designed specifically to detect Organophosphate in liquid samples.
Organophosphate compounds (OP) account for the largest class of rural and urban poisons in the world that are used to kill pests but can also be toxic to humans. OPs cause toxicity by means of blocking the acetylcholinesterase enzyme (AchE). The AChE-directed OPs react with a serine residue that is located at the catalytic site found within the AChE gorge. The OP targeted enzyme is no longer able to hydrolyze ACh, resulting in the buildup of ACh in the nerve synapse. This effect causes excessive excitation of the nerves, producing uncoordinated movements, tremors, paralysis and death. Both synthetic and natural(Guanitoxin) organophosphates are dangerous to humans — exposure can lead to visual, coordination, muscular, and neurological deficiencies, and in some cases even to death. In turn, exposure to OP is a significant public health concern which would significantly benefit from an improved detection platform.
Attogene’s Organophosphate detection kit is in designed specifically to detect Organophosphate in liquid samples. For solid samples a simple sample preparation method is performed. The ability to detect Organophosphate is performed is simple and sensitive. The reaction uses a chromophore that can be detected by eye. In the presence of Organophosphate, the rate of chromophore production is reduced in a concentration dependent fashion. The higher the concentration of Organophosphate the less color is produced.
