Diazo Biotin-PEG3-alkyne is useful for introducing a biotin moiety to azide-containing biomolecules using Cu(I)-catalyzed Click Chemistry. The hydrophilic spacer arm provides better solubility to the labeled molecules in aqueous media. Diazo allows efficient release of captured biotinylated molecules from streptavidin using sodium dithionite (Na2S2O4). Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Organophsphates are a class of pesticides that mechanistically target the acetylcholinesterase enzyme. Regulatory guidelines have been set to ensure our food and water are within the acceptable regulatory authority guidelines. Because most OPs are provided in their precursor form, organothiophosphate (i.e., Malathion, Diazinon, Chlorpyrifos, Azinphos, Dimethoate, Terbufos, Phosmet) Attogene’s organophosphate ELISA kit has been designed to detect organothiophosphates which are the main form of the compounds when applied in the field.
Document
This kit can be used for rapid test of organophosphate in liquid samples such as water, wastewater, and solid samples such as wheat.
Propargyl-PEG3-acid is a reagent with an alkyne group and a carboxylic acid. The terminal carboxylic acid can form amide bond with primary amines (activation is needed). The alkyne can form triazole linkage with azide containing molecules via copper catalyzed reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Magen’s HiPure columns are prepared by high quality glass fiber filter membrane as raw materials through membrane cutting, membrane release, ring release, ring pressing, gland, weighing and other processes. HiPure nucleic acid adsorption columns have the characteristics of long-term stability and high binding capacity. Experiments show that the highest binding capacity and binding efficiency of HiPure nucleic acid adsorption columns are basically unchanged when stored at room temperature for 4 years.
The series of nucleic acid columns produced by Magen Biotech are based on carefully selected imported glass fiber membranes (GF/B, GF/D, GF/F). Columns production processes such as polypropylene injection molding materials, injection molding process, and downstream membrane packing and compression rings are strictly controlled. This is to ensure that the column has extremely high adsorption capacity and long-term stability. Compared with conventional products on the market, Magen’s columns are with varieties, and binding rate will not change when stored at room temperature for 4 years.

Adsorption Mechanism
Based on the negatively charged DNA skeleton, it has a high affinity for positively charged glass fibers. In high salt and ethanol solutions, DNA/RNA binds to glass fiber and interacts with hydrophilic matrix on silica through hydrogen bond. DNA/RNA is tightly bound. All pollutants can be removed by washing solution. At high salt concentration, nucleic acids selectively bind to silicagel membrane, while other pollutants, mainly proteins, are removed by membrane washing.
