DBCO-PEG8-NHS Ester is a click chemistry molecule cosisting of an NHS ester that is reactive specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. PEG8 spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The contamination of pathogenic microorganisms and their toxins in food and water is a serious issue for human health and safety. For instance, enterotoxins (SEs) produced by Staphylococcus aureus (S. aureus) are heat-stable, meaning pathological activity remains even after exposure to sterilization techniques and digestive proteases. Among the SEs, staphylococcal enterotoxin A (SEA) and B (SEB) are confirmed toxins which cause enteritis and food poisoning. Symptoms include nausea, vomiting, diarrhea, which in severe cases, may lead to fatalities in children and the elderly. These SEs, known as superantigens, non-specifically activate Tcells, leading to proliferation which ultimately results in T-cell elimination. This activation directly and indirectly induces a massive release of inflammatory cytokines.
In addition to acute poisoning, researchers reported that these toxins may play roles in the pathogenesis of autoimmune diseases. More specifically, intestinal dysbiosis (enteromicrobial imbalance) was found in patients with rheumatoid arthritis (RA) and which may overwhelm the host immune defense functions by chronic exposure to excess amounts of these pathogens (7, 8). In animal models, SEs synergistically play a role in the pathogenesis of autoimmune-related diseases, such as atopic dermatitis, food allergies, colitis, arthritis, and systemic lupus erythematosus.
Attogene is offering this highly robust test to detect SEB by lateral flow in diverse liquid sample types.

Operation procedure and process:
Operation procedure and process:
Take out the liquid components of the kit in advance, thaw at room temperature, and shake to mix.
Prepare freeze-dried reagents according to the number of samples to be tested, negative and positive controls, and add 37.5 μL E buffer to each freeze-dried reagent.
Select the appropriate nucleic acid extraction method and reagent to extract the sample nucleic acid
Add 10 μL nucleic acid template to the reaction tube (the amount of template can be adjusted to be filled with sterile water; That is, 10 μL nucleic acid template plus sterile water), 10 μL positive control template was added to positive control, and 10 μL sterile water was added to negative control
Add 2.5μL B buffer to each reaction tube and close the tube cap (for multiple reactions, it is recommended to add B buffer to the inside of the tube cap)
Thoroughly mix the reaction tube upside and down for 8-10 times. After mixing, shake (or rapidly centrifuge) the reaction liquid to the bottom of the tube and transfer it to the amplification zone.
