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.
Rapid dipstick test for detecting Staphylococcus Enterotoxin B (SEB) in liquid samples
Detects 10 ppb and greater Staphylococcus Enterotoxin B (SEB) in the sample
These kits provide a rapid method for the isolation and purification of total leukocyte (white blood cell) RNA from mammalian blood samples. These kits are supplied with an RBC (red blood cell) Lysis Buffer for selective removal of red blood cells and fractionation of leukocytes by centrifugation. Isolation of leukocyte RNA results in improved expression profiling and other downstream applications by removing the masking effects of some RNAs which are very abundant in whole blood, such as globin mRNAs. These kits are able to isolate total leukocyte RNA, including both large mRNA and all small RNA species containing microRNA (miRNA) and small silencing RNA (siRNA). The purified RNA is of the highest quality and can be used in a number of downstream applications.
Leukocyte RNA Purification Kit (Spin Column)
This kit provides a rapid method for the isolation and purification of total leukocyte RNA from mammalian blood samples in 40 minutes. Allowable blood input ranges from 10 μL to 2 mL or 3 x 106 Leukocytes
Leukocyte RNA Purification Plus Kit (Plus)
Norgen’s Leukocyte RNA Purification Plus Kit provides a rapid method for the isolation and purification of total leukocyte (white blood cell) RNA from up to 3 mL of mammalian blood samples. Complete 10 purifications in as little as 40 minutes.
Leukocyte RNA Purification 96-Well Kit (High Throughput)
Purification is based on 96-well column chromatography using Norgen’s proprietary resin as the separation matrix. Purification can be performed using either a vacuum manifold or centrifugation. Norgen’s kit allows for the isolation of total leukocyte RNA, including all small RNA species. The purified RNA is of the highest quality and can be used in a number of downstream applications including real time PCR, reverse transcription PCR, northern blotting, RNase protection and primer extension, and expression array assays. Allowable blood input ranges from 10 μL to 1 mL or 1.5 x 106 Leukocytes.
